    Cleaning Balance Cock With Hair Spring

    Big thanks, I did not know that. I would have dunked the complete balance and all in lighter fluid along time ago. I was Afraid of loosening the jewels. Darn. Sent from my iPhone using Tapatalk Pro

    How To Chamfer A Watch Case

    What I'm trying to do is create a chamfer at a precise angle where none previously existed, then go from there. Since I don't have 9 grand lying around, and since I really haven't found or been given anything of substance thus far, this seemed like a good idea to try out. I'm not exactly the sharpest knife in the drawer, but I do get the steak cut. If there's something you know that you can educate , I'm definitely willing to listen!

    Porcelain dials

    I thought I would clarify this you're not going to see the metal on the backside of a enameled dial. When enamel is baked on the metal it has a problem of having a different thermal expansion than the metal itself. This means that when it cools after being fired the enamel has a tendency to crack. To prevent that enamel is put on the backside of the dial to cancel out the different thermal expansion on the front side. For example this is a Hamilton pocket watch dial front and back. notice typical of American pocket watch dials the subsecond is recessed and is actually a separate enameled dial soldered the main dial.

    Rolex Datejust 1601 replacement hands

    I'm more saying that because of the slight possibility it could be fake but I just got it in hand and it looks good to me. Anyways back to my problem, do you know where I can source the hands for it? It seems like the cost of the hands isn't much but every Watchmaker I've talked to wants to preform a full service on the watch which for me is too expensive and isn't needed as it was serviced last year and runs perfectly.

    How To Chamfer A Watch Case

    I'm not really sure what you're trying to do; if it is refinishing an existing bevel this won't do it, if it's creating a new bevel then a file would work far better.

    How To Chamfer A Watch Case

    True, but at least I won't have to spend 9 grand. LOL I'm aware what it is, but do it enough times and it'll give me something I can work with. I'm not really going for perfection. We'll see what happens! Sent from my iPhone using Tapatalk Pro

    How To Chamfer A Watch Case

    That's a deburring tool for removing burrs and sharp edges from machined parts. It will probably put a chamfer on a sharp edged case feature but it will be ugly, and need filing and further work to be nice looking.

    How To Chamfer A Watch Case

    Well, after spending a couple hours of researching (on top of the previous research!), I think I've found something... SHAVIV 29249 Bonus Pack Deburring Tool Kit for Extra Close Work with Mango IIB Handle (11 Pieces) https://www.amazon.com/dp/B003JY7LXI/ref=cm_sw_r_cp_api_c3DDBbNYNZZME From what I've seen on video of this, this particular tool will do a 45 degree angle. There are others that will fit the handle for different bevels etc., but you get the idea. I'll give this a go and let you know what I discover and the results. Sent from my iPhone using Tapatalk Pro
  12. Well unless the markers were changed for some reason, the sigma indicates they are white gold.

    Need a Pocketwatch with a broken staff

    This guy always seems to have loads https://www.ebay.co.uk/sch/ramps333/m.html?_nkw=&_armrs=1&_ipg=&_from=
  14. I feel your pain, although I have been taking night classes for 2 1/2 years on watch and clock repair I'm pretty sure I wouldn't pass any of the BHI exams, but one day would love to do the BHI course, I hope you manage to pass it next time you sit it. Any chance you could give just a brief overview of what was in the test?

    Thank you Michael, that clarifies it somewhat. I do believe when I took the movement out last time, the dial has a metal backing. Thanks to all for the info.

    BHI 2018 Examinations

    Hi everybody. I was at the D1 theory exam this year (2018) I have this morning found out my result which was a fail (42%) and to say I am devastated is an understatement. I wish the exam wasn't biased towards clocks but that's life I guess. Roddy I believe you're the chap who was stood in the common room before the Theory exam as you were telling the guys about your experience with the case/pendant? A pilot was talking to you if I'm not mistaken. I'd be interested to know your theory result as you said you didn't finish. I finished with literally 2 minutes to spare and that was going flat out! Too many drawings, narratives and calculations for the time allocated I believe. Surely this year the pass rate would be lower than average? Kyle
  17. Over the next few months I (or possibly longer depending on my skill) I need to machine a balance staff and fit it to a pocket watch for my watch course. I've gone through all my pocket watch movements I have and most have good staffs and those that don't have too many other problems to want to attempt to fix. If anyone comes across a reasonable quality pocket watch that other than a broken staff doesn't have too much else wrong with it please let me know as I'm loath to remove a good staff from a balance just so I can try and make a replacement. I've started trawling ebay, but haven't come across any yet that are of nice enough quality I want to invest a lot of time and effort in making a staff for that the sellers doesn't want too much for. I'm sure there probably is one for sale on ebay, its just my searches haven't found it yet, so if you come across one please let me know. I would prefer a pocket watch that has the jewels fitted in chatons, but not one that is overly expensive. I'm pretty sure this doesn't break the forum rules as I'm just asking people to help me find a pocket watch for sale that meets my needs on ebay, not asking for people to sell me anything via the forum, but if it does please delete my post. This weekend I hope to find time to make a trial new mounting board for my BTM watchmakers lathe to see if the Chinese sewing machine motor I bought will work with my lathe. If it does then I will buy some nice wood and build a better quality base as the motor I currently have with my lathe has no speed control and runs a bit slow and I need to replace this before I attempt to turn a balance staff.

    Rolex Datejust 1601 replacement hands

    From the info I have from the seller the dial was relumed by RSC which based on how well done it is I can believe. From what I know the Singapore RSC did this for some time instead of outright replacing the dial which makes me very happy if true. Once I get the dial in hand I'll be able to confirm if the markers are white gold or not but I think for the price I paid I got a great deal on a rare dial.

    Fitting Domed glass crystals

    If the dome is not severe, use a scrap of pine or fir (soft wood) as a buffer and a regular arbor press. You could also apply (a TEENY-TINY) bit of Molykote 111 to help the glass slip into the ring. If it's a real PITA, I'd be looking to the factory Seiko tool/die for the job. I bet you could order the tool (once you figure out what exactly it is) from an authorized Seiko shop. Or, maybe let the shop press in the crystal if they have the tool on hand. I'm not above going to the "experts" when I'm well out of my comfort zone with these things...
  20. Welcome. Yes, the "sigma" dial was used to indicate the change to white gold hands and indicies, over the former stainless steel used prior. This change was due to the corrosion of the hands mainly. This dial would probably have the classic straight hands with the lume tracks in their centers. Many sellers have aftermarket ones, but for white gold you may have to wait for a genuine set to come along, and they would most certainly be (non-glowing) Tritium lume material. What is interesting is that I've never seen a sigma dial using anything other than Tritium, as indicated on the bottom of your dial... Is this a re-lume perhaps? You indicated it as a service dial, but I've never seen a sigma marked service dial. A luminova replacement would have "SWISS" only at 6 o'clock. I have seen "T<25" marked dials with luminova, (early service dials) but never sigma dials before. I suspect it is an original one that was re-lumed in the past. And from what I can see, it was done very well! Please correct me, if I'm off base, with some supporting information that lead you to the conclusion it is an original service dial. I'm quite curious...
  21. I finally got back to this last night. The good news is that the aftermarket barrel I ordered looks like it will work perfectly. Gear pitch and form factor seem correct. The bad news is that it doesn't. The aftermarket barrel arbor has a bottom pinion of 0.9mm, which presumably fits a 1mm stone bore. The "fake" arbor has a pinion diameter of 0.85mm, and the "fake" stone seems to be 0.9mm bore (I cannot measure that accurately enough). So it doesn't fit. (I didn't get to checking the top bore yet). So, because the "fake" spring is filthy and might be broken (I have not pulled it out of the barrel yet, but it has some odd appearing areas) I decided to swap the "fake" arbor into the aftermarket barrel and mainspring. Maybe tonight I'll finish that up. I have the "fake" one out, but haven't popped open the replacement one yet. The other option is to turn the arbor pinion of the replacement barrel, or to replace the bottom stone with one of correct bore. My reservation with replacing the stone is: if the bore is wrong, the OD might be as well... I'll see if I can find an inexpensive one to try out maybe. That, and I've never replaced a stone before, so there is room for error there... (better to practice on a junker like this than a genuine mainplate I guess!) Final option is to remove the replacement spring from the replacement barrel and install into the "fake" barrel, but I don't think that will be necessary. Plus the fit and finish of the replacement one seems so much nicer... If it comes to that, I'll stash the complete replacement barrel and just get a replacement spring. Ultimate option is replace the mainplate with a genuine one. That's obviously expensive and I foresee to potential for MANY problems adapting the "regulation system" of the fake movement into a genuine main plate. Oh, just replace that too... And so it goes...

    An interesting piece I found

    Oh, OK. Then just grab your calipers and see what size the pinion is for the hour hand. Ofrei has tons of generic hands, and I'm sure others do too. Get a few that you think might look nice and try them out!

    Porcelain dials

    I would say with almost certainty that it is an enamel dial, which means it will have a metal backing to which the enamel is baked onto. I would be amazed if it was porcelain, which does not have the metal backing (image a porcelain plate or vase - no metal backing - solid ceramic like substance) .
  25. Mattaphysics

    An interesting piece I found

    No, it's a regular pocket watch. Made by Ingraham, it's for sailing. The dial denotes how's many bells for the time and does the different watches eg. First watch, mid watch, etc... Yeah it didn't look like a seconds hand would be on it, but there's definitely an hour hand I just don't know what size or type. It's a very cool pocket watch though. Sent from my Z956 using Tapatalk
