    Hi All, Something to brighten up a gloomy day! Picked up this absolutely stunning old Tudor 9ct gold recently. According to the previous (original) owner it had barely been out of the box in his ownership since it was presented to him in the 1970s as a long service award (happily for future owners it wasn't engraved). Original strap (transferred off for now in favour of something more my taste), signed buckle, signed crown, and all of the original box and paperwork in absolutely mint condition. You can tell it's hardly been worn when you wind it and adjust the hands, it still feels really 'tight' (but not too much as to indicate an issue!). Can't imagine there's too many out there that has all this in such fine condition. Very pleased with this find!

    When I see a clock like this and the word RESTORED is present in its selling advertisement I always like to look. 9 times out 10 I’m disappointed. They are never properly restored. The people who undertake the work charge very high prices and you end up with something like this. Screws unattended. All should have the burr removed from their heads and highly polished Platform screws. If signs of bluing. All should have the burr removed from their heads and highly polished and re-blued. Back plate pins should be the same size, where cut should be nicely rounded off. All pins should be cut and nicely rounded off. They should be steel not brass. They should be straight not bent. Parts missing should be made and replaced. This clock is missing the stop work. Barrel arbors should be tidied up and the flat sides polished. Hand setting part should be tidied up and the flat sides polished. The centre wheel end should be polished. The same goes for the hand collet https://www.ebay.co.uk/itm/Beautiful-antique-French-striking-carriage-clock-c-1860-5-restored-10-18/113478774506?hash=item1a6bdcaeea:g:Ba8AAOSwQ5pcHnCS

    Be very careful when it comes to buying from ebay. I see that BHI oil comes from China. Most Chinese watch tools are very poor. Myself I would leave it alone. Lubrication is very important for watches, you must use the correct one’s if not you will end up with a movement giving poor performance. Buy a recommended brand from a watch material supplier.

    I think your post misses a few salient points, people who have worked their way to this site may well have done so out of economy and wish to learn to service the watches that they have acquired over the years, and by learning to do so have more money to spend on their hobby. There is no doubt that a quartz watch is more accurate than a mechanical watch but do you really need to time your life to the second ? do you need to time it to the exact minute ? you only need a reasonable amount of accuracy in life and certainly in most cases not to the second, the mechanical watch is in no way totally obsolete, it will always exist as long as people use sites like this and enjoy taking them apart, repairing and learning about them. What I do think will happen is that there will be a resurgence in mechanical watches and it wont be led by the high priced major players in Switzerland.

    Well gents a couple of weeks ago I jumped on a post about microscopes, at the time I had just ordered from AliExpress one of these, a 600x mag with built in screen etc etc. well it arrived and it’s great, it really is, the screen picture is very clear and the height of the screen and microscope are adjustable to the height where it is easy to manipulate hairsprings with tweezers in the vertical position. For jewel inspection etc you can lower it down to take advantage of that 600x mag and get a proper look at jewels and staffs etc etc. all in I’m very happy with this as it saves me having to have a laptop on the bench with leads etc getting in the way and also finding a program that works with the microscope. This one accepts a memory card and will take stills and 1080p HD video aswell all in one unit so it’s ideal. It’s light and as you can see quite compact, it’s powered by its own internal battery that has a 6 hour life before charging is required , a plug ( albeit a Euro 2 pin one ) and a usb lead is included for charging purposes. my only gripe is that you don’t seem to be able to turn off the led light when it’s switched on, but that is the only one so far. Well with the £40 and 3 week wait for it to arrive from China.

    This could be an eccentric 4th wheel, I didn't time it but the cycle seems close to a minute. Perhaps a bent pivot, perhaps damaged pinion leaves on 4th wheel. I don’t know this movement but if it is central seconds with supplemental pinion at center it could be bent and rubbing in center tube, same if ghe 4th wheel itself is central.

    Archie Perkins' book on lathes and Marvin Whitney's book on marine chronometers give quite detailed descriptions of the use of these tools, the Levin book has some good info too. They are what a regular machinist would call a grinding attachment. They can produce excellent results, but the preparation of the laps and setup of the tooling is very time consuming. If you're looking for an easy way to finish balance pivots you're better off getting your basic turning on point and finishing in a jacot tool. If you want to avoid the jacot then wig wag tools (Perkins and Levin go into detail on them) are a much faster solution.

    The Expanding the Seiko Collection

    Added a couple new watches to my Seiko collection last night I thought I would share. The first is somewhat underwhelming at first glance, and what does one say about an underwhelming watch? It has good bones, it’s a good foundational piece, etc. etc. Well in my case none of the above. The watch was a match to one I already own a “Seiko 5 Automatic 6119-8400” August 1969, WATER PROOF with three mouth spread between the two watches probably as close as ones going to find without divine intervention. Why do I want two? I don’t, I want three…lol anyone that caught my interdiction will know I am on a mission, put together three matching collection of vintage Seiko’s to pass on to my three sons when I am not around. So as far as this watch goes, I am 33% away from my goal. Found in the UK. Second watch is just fun and considered a TV watch and one that screams 1968-1970 all over again.This is a Seiko 5 6119-5400, Square Automatic day date 21 jewels, original wristband. It has an interesting band that is claimed to be original wristband and found in Egypt. I generally try to keep my collection grounded around the infamous 6139, 6138 series but one has to occasionally push the boundary. All the best, Will

    Record 107c puzzler of the day

    A likely reason is that the square hole in the ratchet wheel has become rounded and is therefore not engaged properly with the barrel arbor. The stem may well result in the turning of the ratchet wheel as expected but this may not actually be turning the barrel arbor properly. [However because the screw is directly in the arbor then if you use this method then the winding does seem to work]. Also obviously check that the ratchet wheel is properly seated. Initially I would suggest removing the ratchet wheel screw and gently turning the stem and observe what happens to the arbor and ratchet wheel. [The ratchet wheel should not pop off in the absence of the screw if you are gentle but if in doubt you can always hold the wheel in place with (brass) tweezers].

    Invest in Moebius, it will last years depending on how much watches you service...

    Watchmakers lathe vs mini lathe

    you need 2 maybe 3 types of lathes; jewelers lathe ( used with gravers), "mini lathe (what ever that is good for". and a compound lathe (gear driven cutting). Oh heck, get a mill also. vin

    Members on here have reference books, which show the keyless works of thousands of movements. Experience can also play a big part. Bestfit watch parts ref book is one of the better books for this, there are many different types, some for American, Russian Swiss just to name a few. So we only need the photo.

    Movement identification

    Cheap Chinese you said ... cheap Chinese it is. DG 2813 ... DG meaning Dixmont Guang Zhou ... or nothing as there are certainly multiple manufacturers. You can find stems on the net but the problem is you could pay $9 for the stem only and $16 for the complete movement. Depending on where you live some close forum member could send you one (I'll check my drawers and I'll tell you). Another problem is : do you have the crown ? If you don't have the crown ... I'm not certain that watch deserves the effort and money you could put in. If you still have the crown and your mate really likes it you could swap the movement and put a better one inside : - Miyota 8215 ($50 and you can keep the same handset) reasonnable choice - 2836 clone ($90 and you must source a matching handset so spend more $) the best choice in my opinion if your mate wants to keep the watch ... don't forget you will have to modify the dial's feets. - wait for a used ETA2892-2, source a matching handset and put that in the watch case ... then search for a 1120 Omega rotor so that that fake Omega watch can have a faxe Omega movement inside ... I'm just kidding of course But, once again, the question is "does that watch deserves the money and work ?" You should show us the face and some details.

    Watch of Today

    Watch for me today is this lovely vintage Oris that I gave a little going over last night. Slightly on the smaller side for my personal taste but a nice old watch nonetheless.
  17. 2 points
    Added this Vostok "Cadet", or also called "Junior" or "Mini". It has a 32mm case (ex.crown) and nobody is quite sure whether it's a man- or a woman's-watch. Some suggest that these were issued in the '80's to the woman serving in the Russian Navy, but then again, they were also available to the civilian market, product number 461285 and powered by a 2409 movement. Often these dials are full of aging cracks, but this one, even-though used, has a mint dial. These Cadets are, for one reason or another, not much beloved in the collectors world and therefor cheap to get. Regardless, they are still a piece of the CCCP history and aren't produced anymore ..... I like this "dolphin" issue

    Here's the one with the added ring. Customer had a case he wanted to use for sentimental reasons and fit a vintage monopusher chrono in. Not the best pic but only one I have. Movement was old enough to be pin setting you can see the added pin next to crown.

    D. I. Y. Watch Timing Machine.

    So I managed to get everything together and got my first readings using a standard stereo pre amp I bought for a turntable several years ago. Sadly i still didn't manage to get my diy microphone preamplifer kit to work (the one i mentiont in one of my earlier posts). At the moment I think about ordering a already built preamplifier board but I do not have the qualifications to judge with would do the job (or at least would lead to better results then with my current solution. That's why I am again counting on your help. There are some pretty cheap options but I don't know how to judge the all over amplification from the specifications given. My current preamp has the following technical specifications: Input Impedance 100kOhm, 5mV, Output Impedance 100kOhm, 250 mV, S/N-Ratio: >50 db, 12V DC, 100mA The options I'm most into at the moment is something like that cause its cheap and and may be an improvement (however I'm not sure about that) https://www.ebay.de/itm/TDA2030A-Audio-Power-Amplifier-Board-15W-AC-DC-12V-Assembled/292336674126?hash=item44109fa54e:g:nUAAAOSwKrhVZbo1:rk:28:pf:0 or even simpler: https://www.ebay.de/itm/TDA2030A-Audio-Power-Amplifier-Board-15W-AC-DC-12V-Assembled/292336674126?hash=item44109fa54e:g:nUAAAOSwKrhVZbo1:rk:28:pf:0 There are more fancy options like https://www.gearbest.com/other-accessories/pp_009478010615.html?wid=1433363 or https://www.gearbest.com/other-accessories/pp_009478010615.html?wid=1433363 but I have absolutely no clue if they would be suitable for the task at hand. The thing is that (as you surely have noticed by now) do not know the first thing about electronic. But I'm eager to learn, I just don't know where to start. So thank you for your time cleaning my mess. On the bright site as I said, I managed to get my first signals and I'd link to share some pics of that: This is my set up at the moment and some readouts from two of my watches (I hope it's okay to post the watch-o-scope screenshots). Today I broke the piezo trying to replace the cabels between it and the jack with shilded ones and now I have to get some more piezos to get my DIY-timegrapher running again. Let me know what you think and thank you very much!

    I think if you try to shrink fit it it will break, if not upon installation then down the road from being under tension. As above, a gasket or glue are the usual ways to install. Be wary when cutting away the inside of your back as you get toward the tapered sides you will lower the level of the glass, possibly crashing into the movement. On one odd customer request I once added a pressed in stainless ring to the opened back which blended in and added the necessary height.

    Round mineral glasses are available in all sizes for little money. Thickness starts at 0.8mm afaik. They are glued in or pressed using a gasket. Window must have 90 deg edges. A too thin back can be an issue, test before cutting! Frank

    Watch of Today

    Here comes a surprise IWC Shaffhausen Watch Co.. Flatline Quartz.. Have I gone over to the dark side.. No curiosity killed the cat but not me, something with the high end quarts still resembles an mechanical movement, it just misses an escapement and balance otherwise you find a 7 juvel train bridge and a nice movement work. The powerhouse is an IWC C.2250 with the stamp of V8 promising an roar when applied on the wrist. I have seen the V8 sign is associated with Tissot but it pops up on al the modern quarts movements and mechanical movements I have looked at lately, what does it stand for?

    Manodero and anilv, Thanks so much for looking at my intro and commenting on my watch! I apologize for taking so long to respond here! I won’t let that happen again! I’m full blown committed to watchmaking these days and am actually going to switch careers and jump into watchmaking full time at the beginning of 2019. I’m so excited as I am so bored with being a software consultant for a large fortune 500 company, although it has repaid me with a comfortable life which I am truly greatful for. To answer your questions about how I made that dial I’ll list out the steps I took, but how you paint on the “Rolex oyster perpetual Datejust... superlative chronometer officially certified” is something that you will have to choose how to do on your own. You can have a dye made of the dial with the writing and use it as a trace, you can use an engraver and punch the letters a bit more into the dial so that when you paint your first layer you can still see the outline which is what I did. I’m sure there are several more ways. Step 1) if you are working with a Rolex dial and I suggest you do so so you can form this template, take a sheet of paper and trace the dial, at exactly each hour and each marked minute, draw a line from it on the paper so that at the end your paper looks like a sun with a bunch of rays but make sure you make the lines longer where the hour tacs are. Now take a compass tool and put the pin in the center of the dial and stretch the compass to the inner ring of the minutes tics. That is your distance that you need on your dial so make that ring on your template sheet. Do the same for the outer ring. 2) I took an engraving tool and went over the letters on the dial with it so that they were deeper set into the dial. I also went over carefully and this takes a long time.. the inner and outer rings of the minutes area and engraved each minute tic. 3) clear the dial by picking off the tacks and the Rolex crown insignia with a tweezers. Clear the paint by using solvent or by using a professional jeweling hand held polisher or sander if the dial is metal. Take a brass brush and lightly remove the metal. Make sure you do not go too deep. Try to make it as even as possible. 4) place a toothpick in the center of the dial, suspend the toothpick (I did it with a clamp that usually holds wires that need to be soldered), make sure no dust in on the dial, and spray acrylic spray paint onto the dial making sure to hit the dial from directly above and spray from 6-10 inches away. Make about two quick sprays and let it dry. Take a look and make sure no dust particulates are stuck in the paint. Also because you engraved the letter make sure you can still see them as the paint will be dented at the lettered spots. 5) use acrylic paint and micro brushes and paint the letters in. Do not paint in straight lines. Instead make small dots.. this takes practice to get right. Because the dial is a bit dented in those spots the letters will not look raised from the rest of the paint.. you wouldn’t think it mattered since you have to clear coat it at the end but it does make a bit of a difference to me. The small dots will Give you a better idea of how straight your line will be. Connect the dots when you’re confident of your line. You need to do this with a 15-20x loupe or a microscope. If you make a mistake you have to soak your dial in solvent and start again or decide to live with it. Let the letters dry overnight. 6) reaffix your dial with a toothpick in the center and suspend it. This time use a clear coat that a) dries fast b) is heat resistant c) will not yellow in the sun d) will not crack for many years. I use spraymax 2x glossy clear coat. Spray just once and let dry. 7) You can buy Rolex crown stickers and you can also use the original Rolex crown that was in the dial but if you do you need to put two pieces of peg wood into the holes of the spot where the crown is and work with them in the holes each time you spray. You can also purchase diamond sticker tacs for watch dials. I use these because it’s way easier than putting peg wood into each tack hole in the dial. Put the dial in your template and stick each diamond stick exactly where the hour markers are. It’s coming together now right! 8) I usually spray one more spray of clear coat onto the dial when I’m done setting the diamond stickers. This ensures me that the hour marker diamonds hand on tighter. This last spray must be thin however because you can get bubble type weird bunches of clear coat at the edge of the diamonds. Here is a picture of a dial I did with ticks but this took a really long time and I made a mistake when I was writing in the letters but I lived with it. Btw I’ve seen dials just like mine online actually for sale by an Asian company. They are not too expensive but the process of purchasing them is a pain. It’s a western union type of thing.. Personally I’m Leary of the whole western union deal but can see why it’s needed. (The dial is kind of oily sorry) I’ll write out instruction for printing dials tomorrow! Hope this helps. Again there are many ways to copy the letters and get them into the dial! You just have to research!
