I received a Vostok Komandirskie in the mail last week. It's a non working watch with many minor issues. But for today, I'll just talk about the broken mainspring.

I have a spot welding machine, so repairing a broken endpiece like this is relatively easy for me. I just clean up the pieces and clamp them between the spring loaded jaws of my spot welder and hit the switch.

But if a spot welder is not available, what other methods would be used to repair a broken tail?

Forget the old broken spindle piece, heat end of the spring to a glow to bend a 90 degrees reheat to continue bending to 180 degrees, quench in old automotive oil. You have a one piece spring with a bend that functions and lasts longer than the original spindle.

Works like a charm

      Can someone please explain watchmaker service mark interpretation?

      By HorologyHead · Posted

      H Watch Repairers—is there is a ‘standard format’ for the service marks or codes lightly engraved inside cases of pocket watches or wristwatches?   Sometimes I can see there might be a reference to year/ month but other times am confused. I’ve included an image of the rear of a 1951 Hamilton 992B Railroad pocket watch as an example. Thank you for all information you can give, Mike

      Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary! Best wishes, Mike

      Seiko 6601 Tech Sheet?

      By JohnR725 · Posted

      yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here

      An intro…

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.
