DW's Mystery Movement


Akira

Recommended Posts

Hi guys,

some of you might remember that I'm the owner of a V1 MM 6263 from DW

711c10f2.jpg

The stem broke quite some time ago and the one DW sent before he starting [censored] with members money, doesn't fit.

Neither does a regular 7750 stem.

RA said the movement is rather ST19 than V23 based.

So anyone got an idea what I can do to get a new stem?

Anyone got this movement as well and could snap a pic of the stem?

Best regards

Akira

I have the same Mystery Movement in my DW 6263. I needed a stem as well about 9 months ago when Gonzales was working on the franken mods. DW sent me a new stem, which didn't initially fit it, but Gonzales cut it and worked it to make it fit. He didn't know either where to get another stem besides DW, so was able to make it work.

Hope you find one soon. Good luck. :)

Chances are there is a stem that is very similar and can be easily modified to fit. Modifying an existing stem is a lot easier than making one from scratch.

It is better to start with a stem that is exactly the same where the flats are and has the same thread size but the hub, detent groove, and pilot are fairly easy to modify. Most repair guys with a 'ww' lathe can do it.

'ww' = watchmaker type lathe

Anyone who discovers a close match can post what it is.

Its not a 7750 based as a 7750 based is a tri-compax.

These Chinese movements are copy of bi-compax Seagull,

non working chrono hours counter at 6, just a glued hand, not very realistic,

Wiesn, does have a point but,

the only upgrade I'd do, would be a V72 and I don't have the spare cash lying around at the moment.

So if your watchmaker can do a stem at a reasonable price, I'd go with it.

That movement has been working for years without problems,

I just got unlucky with breaking the stem, when I had a gen crown/tube installed.

The movement is not a copy of anything..., it most certainly is not a V23 (or 72, the 72 is simply a 23 with a 12 hr counter added) I have tried all the stems possible and none fit.

I finally found a Bestfit stem that was close and needed some tweeking in the lathe to make it fit...

Thanks for posting Zig.

That's pretty much what Rolexaddict told me. That movement has nothing to do with a V72 nor V23.

It's some bi-compax-who-knows-what.

Very strange :lol:

However, Donerix has been very helpful so far and I might resolve that issue.

Thanks everyone for chiming in and please continue if you have more input.
