Hello Everyone! hope everyone having a nice new years!

It's been pretty busy since summer. Mostly standard overhauls and custom crystal cuttings. Nothing too exciting.

Here one that I'm working on now. Seiko 6020A came in with a battery that leaked and was sitting in there for ever. Also a loose ruby. I haven't really encounter a jewel coming out before. Couldn't really find much online regarding resetting stones. I do have a full  staking set, and also jewellers stone setting tools. Was thinking maybe do it like a channel set stone where you would just compress each side of the metal to try and tighten the stone. Still trying to think of other ways. I think i read on the forums somewhere that they used some glue? that didn't seem like the best option.

If anyone have some insight and able to share your experience with me that would be greatly appreciate.

I've looked into a replacement movement from a few supplier but non have it in stock anymore. and non offer and option for a modern replacement.

Still waiting to hear from Seiko so hoping they will have a replacement movement for it.

 

Mkay.

If you can beg, buy or borrow a jewelling press then the right answer to this is to fit a jewel with same hole size but the next size up external diameter.  Jewlling presses come with specially sized reamers to ensure you open up the hole in the plate perpendicular with the correct interference fit.

Mark explains here how to do all this...

      I've bought brands like Citizen, Seiko, Titoni, Tissot, Roamer. Strange thing is many of them were using ST96 movements. I'm not sure if the ST96 is original to that model or whether it was a replacement movement.  All the watches with nice looking dials were obviously refurbished, after-market dials. And all of them had over-polished watchcases. Some of them had non-original hairsprings, rejewelled pallet forks, watch crystals that don't fit and glued in with a generous amount of glue. One of them was totally not working because the pallet jewel was loose to the point that it almost fell off. But the sellers were very nice. The seller of the non-working watch gave me a complete refund. Some of them gave partial refunds. I would say don't by luxury watches on the internet, regardless of the country the seller is from. Don't believe the "serviced by master watchmaker" statement. Have realistic expectations. ( Do expect the occasional complete junk.) Do expect to do a complete overhaul and major repairs. Otherwise, watches from Mumbai are great. For clocks.... I'm not so sure.

      Regulating an F6922 without a timegrapher

      By WpgRob · Posted

      In 2020,I picked up an Orient Mako II online. It ran at +15 seconds per day and after 3 years of resets more than weekly, it was time to crack the seal and take a shot at regulating it. Not having a timegrapher, I used a spreadsheet to track the time, referenced the Canadian NRC website, wore the watch between adjustments, and used the back end of some tweezers to lightly tap the regulator daily until it ran to within one second per day.   Two months later, it’s still running to within 1 second per day when measured over a week or longer, while daily variations are up to 9 seconds per day. For my purposes, its overall stability is surprisingly good. Is this method of adjustment “better” than adjusting to 5 positions using a timegrapher, since during the adjustment period the watch is already in the environment in which it’ll be used?

      @HectorLooi Yes, I would say that Mumbai has the highest liquidity in terms used watches. How was your experience with these used watches and what watch brands did you buy used? I have always found the vintage luxury watch segment in India a bit shady. Quite a few are genuine watches with genuine matching parts but just not from the same one.

      Interesting interpretation of "traditional". I would say that Loctite is definitely the up-to-date and appropriate stuff to use, however, it is a relatively modern solution. Before the advent of such esoteric solutions I believe that the "traditional" thread locker of choice may well have been a sugar solution. Once applied the water would evaporate and the sugar would crystalise, locking the threads tight.
