Hi guys, I just wanted to show my next project, a Seiko 6139-6005 chronograph. I think we can skip the discussion whether this is actually a Pogue or not ? The case is a bit rough, so I want to try to refinish it a bit. My plan is to file it down from rough to fine grain first, then polish it and apply the circular brushing in the end. I will orientate on the video "My Retro Watches" made about the refinishing of this case. At first I thought about replacing the bezel, but in person it looks a lot better than in the pictures. As it didn't came with a bracelet I need to think about that too. I think I will go for an uncle seiko bracelet, since I find the original bracelets a bit expensive for what they are. The dial is in really nice condition, the lume has slightly darkened at the edges and match with the hands. I hope I will find the first two numbers of the serial number on it's backside, so I have the proof that it wasn't replaced. The movement looks quite clean and isn't running to bad, so that's already a good sign. Unfortunately the (hammer?) spring looks to be from a Seiko 6139A, while this is a Seiko 6139B, so I will have to source the correct one. The chronograph is actually working fine though. The last thing I have to deal with is the crown. It has the correct stem with the spring and the gear that turns the inner bezel, but I think it's no the correct one for this case, it should be a bit more flat. As a result you can advance the date, but not the day of the week, because you can't press it in deep enough. It's the first time I will service this movement, so if there is anything special I should know about the job, or if you have some of the parts I need, then please let me know ? I already have the service manual, so no need for you to upload it ?

The overall condition of this watch is remarkable considering it was assembled in 1959. The metal shows no sign of corrosion of wear but the time keeping was off. So I gave it some long overdue attention. Here it is all cleaned, polished, oiled and now under test.

It has been a bit of saga but worth it. Finally cut a screw for the 8 days French alarm clock. One of the four to fasten the pillars to the base, three were missing. I am almost sure that all its sizes are in French lignes (symbol: ‴), to begin with the pitch of 4 threads per ligne (0.564mm). The head is 2‴ x 1 exactly. The pitch is easy to get if your lathe has a bunch of gears. But the profile is another story, antique threads have rounded crests and valleys. I can only hypotize on how that could be reproduced in an home shop - not easily. Anyway, just like my Swiss-exiled counselor has confirmed, with a bit of care in tool grinding and cutting the result is working and acceptable. Original on the right.

A small but mighty achievement. Well done and thanks for sharing.

For those who were curious of what the 7750 flash-files contained and didn´t have time to download the swf files I did a small compilation of the Swissl@b application a while ago. In this PDF you also get some extra information. So no need for a flashplayer..... ETA 7750 HSL EDITION.pdf And after a quick glance at this issue here is an alternative if you really want to look at these files. For windows users I attached the reader in the zipfile. Just unzipp the zip file to a good place on your harddrive, read the attaced short instructions and happy viewing. [email protected]

Thanks Chris! I should have known to just email you with this question.

Welcome to the forum.

Thank you for your introduction and welcome to this friendly forum.

Hello and welcome to the forum enjoy

I actually used my Jacot this weekend to straighten a pivot on the 24 Jewel Bunn special I have been working on. Great tool if used correctly.

Looks like a trained pro, and someone who frequently uses it.

The polishing machine you have is a dental laboratory/jeweller's micromotor. When I polish metal with a handpiece, I prefer to start with silicone wheels. Silicone wheels come in different diameters, shapes and grits. The coarse grits can remove deep scratches and can even round off edges if not used properly. They can give a nice brushed finish. Medium grits give a nice satin finish. For final polishing, I use a hard felt wheel with polishing compound. But mostly I prefer to switch to a bench polisher with a larger diameter felt wheel or muslin wheel.

If you put a 1.4mm or 1.45mm width mainspring in a 1.5mm barrel, it won't make much of a difference. Technically this reduces the cross-sectional area of the spring, so you would compensate with a slightly thicker mainspring to maintain the same strength. There's calculators available online if you want to plug in the numbers. There's other factors to consider, but from your description and photos we don't have any info on the watch. It looks like a very basic unjeweled movement with a pin-lever escapement? potentially lots of friction there. On the other hand, it looks like an old steel mainspring, so the alloy replacement of the same measurements and thickness might have a different spring coefficient. Lots of variables there. I'd try getting a mainspring that fits and seeing if you can get it to run.

Haha, yes. In school inevitably some student discovers that if you switch "top" with "cock" it makes perfect logical sense, and gets a laugh. Just don't be muttering it to yourself when you're working on the watch or the missus will give you very strange looks.

You just run out of ways to hide your excessive Ebay purchases. "Hey honey...what are those three packages in the mail?" "Something else for the watch bench???"

Years ago when I was married my wife asked me did I want to be buried or cremated. I told her I wanted to be stuffed and sat on my favourite bar stool in the corner of my favourite pub at the bar. That was in the days when I could drink a hell of a lot. These days I'd sooner have a cup of tea.

Mistake No 1 the wife will find you wherever you hide on the plus side you dont need a torch.?

Hi there all, more experimentation going on here I thought I would mix the Dilma with some superluminova c3, now I can't hide anywhere. Check me out.

That is called the "Switch lever" and its part number is 4450 005.

With maybe some tongue.

I don't have that trouble I'm retired and divorced. ?

Masala chai originates from India. You can try getting it from South Asian grocers. You can sometimes get a ground spice blend which you can add to and Indian teas. Or if you are willing to experiment, it's usually a blend of cardamom, cinnamon and cloves. Sometimes ginger and black pepper corns are added too.

Speaking of tea, this must be the Patek of tea's Da-Hong Pao Tea At $1.2 million per kilogram, Da-Hong Pao Tea is the most expensive in the world. This variety has been declared a national treasure by the Chinese government and dates back to the Ming Dynasty. The process used during harvesting remains a closely guarded secret.Have YOU had some? Whoa!

Since I'm also working on one of the bedroom I decide to wear the Marlin while sanding the floors. What better way to test the takes a licking slogan! It did not miss a beat! Since my home as built in 1955 I'd bet many of the workers were wearing Timex watches ?. maybe even the guy that last sanded the floor back than.

Did a lot of work this weekend on a Citizen Eco Drive. Needed a new battery and a new bezel. It looked very worn out. Here are some shots. The double bezel needed replacement and I did a lot of work to recover the crystal. I also got all the scratches off the case with a drumel tool. The end result was amazing. Basically a new watch. When I pushed on the second bezel ring, it would not turn. I put it in my case opener to grab the bezel and then grabbed the movement and forced to rotate. The wire inside the bezel fell into the slot and the bezel now works great. I also made a video on YouTube of some of the action. Sent from my iPhone using Tapatalk Pro

I noticed that the parts list I have for the 410 of course does not have the balance wheel. Refers you to the base calibers 3019 PHF. Then the balance wheel is number 721 but? One of the problems with the Swiss numbering system is 721 is a balance wheel. But that part number does not tell us which balance wheel. For instance I'm looking at AS 1940 Its balance wheel is 721. So basically any older tech sheet for just about any watch is going to Have the balance wheel 721. Which is why you needed additional numbers like the company name and the model number. Later the watch companies got smart and they have unique numbers. To give you an example of the 721 problem I went the best fit online and just looking for Zenith parts a scroll down to the balance wheels which of course are 721 a snipped out a section just see you can see all the balance wheels are 721.we do get the best fit part number for your balance wheel plus perhaps a factory number. The numbers that were interested in our ZEN 3019 PHC 721/1933 721/ZEN 3019. The first is the base caliber the second is the best fit number. The third is the factory number. Then I'm attaching another image the interchangeability list which is interesting because basically there's almost none. But I'm guessing that's because all the variations in the watch basically still use this as the base caliber. As opposed to listing all or parts separately. Not sure if that makes any sense but at least to get a best fit number. Which is helpful for the US material houses where they might actually have one. Although knowing the number now is one material house it looks like you can scratch off the list and the balance wheel was pricey if they did have it. Another option I haven't even looked for that is what about replacing the balance staff that would be considerably cheaper then the balance wheel itself? http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Zenith_410

Hi Ihave attached the following documents on the Zenith, There seems to be nothing specific on the 411 as the base caliber is the 400/410. hope they are of some use to you in you endeavour cheers Zenith 400, 405, 410, 420, 400Z, 405Z, 410Z, 420Z.pdf Zenith 410 (1).pdf Zenith 410 El Primero.pdf 1984529516_Zenith400(2).pdf
