Hello from Shanghai

Recommended Posts

Hello everyone, 

My name is Jason. I live in China, and I have been working on Chinese standard (tongji) movements for about six months. 

I am hoping to improve my skills and start working on more advanced movements in the future. 

I am currently at the end of Course 2 of the Watch Repair Lessons and looking forward to working on the Hangzhou 9000 movement, which is based on the Unitas 6498.

The Hangzhou was my movement of choice because I have read that the Sea-Gull 3600 has some design flaws, and I want to make a watch out of my movement when I have finished the courses. 

Thanks for taking the time to read my introduction.

See you in the forum. 




ps: I have attached a photo of my current work area. Honestly, it was a mess before watching the video in Course 1 about keeping your area clean.

Hi you will be  a good source of chinese movements , good to have you with us.

Thanks again. I hope so.

 The Hangzhou 9310 (Unitas 6498 clone) that I am using for Watch Repair Course 2 was the most expensive movement I have purchased; it cost me 149rmb,  which is  $21usd. I don't know how that compares to other clones of the 6498, but I think I got a good deal.

    • 4 digits Suffixes are the case number, together with the mov.t they make the basic watch reference. You can finnd size specifications oine or measure it. Before giving up on it check pulse at the coil, if there is try a line release or demag. 
    • I am looking at a Seiko Spirit which has the refererence 5M22A on the movement. This watch has seen water ingress at some stage and the movement is badly corroded and beyond saving (although case and dial etc. are fine). I've looked to see if i can find a 5M22A on somewhere like ebay but no luck. There do seem to be other '5M22' references though e.g. with suffixes like 7B30, 6C30 etc. I usually only work on (Swiss) mechanical movements so am unfamiliar with Seiko nomenclature ... I don't know what these suffixes mean and whether they'd be suitable. So basically can someone point me in the right direction and tell me what Seiko movement references I can look at to see if I can find a replacement for the 5M22A please?
    • I'm really bad as far as vocabulary goes in this area but here goes: Judging from the incabloc slot it sure looks like a triple/trior or whatever you call it spring should go in there. I remember working on one quite recently and it had the same system. You'd fit in one "foot", rotate slightly and insert the 2nd and then the 3d. There's quite a couple of variations so maybe they don't use a "traditional" triple spring.
    • This is them fitted to a Seiko. Should have guessed as the movement is a copy of a Seiko.    
    • You may need two trio springs.
