putting in an asian 7750. Is it easy to change from one layout to another?

[Tom]

I've just bought an asian 7750 from Ajoesmith which has the seconds at 9. I was going to use it for a PO Chrono which I have in pieces, but the 7750 in my PAM212 has died (my fault) and I need to have it repaired/serviced

What is the process of transferring the 7750 with seconds at 9 into the PAM212 - there's obviously no date wheel or dial at 6. Is is just a case of snipping off the stem at 6 and removing the date wheel?

Perhaps it would be easier to save this mechanism for another day and get the PAM212 specific one repaired?

Is there anyone apart from The Zigmeister who can do this? I know he is taking some much needed time off for the next 3 months or so.

So many questions....

Tom the problem is that the 7750 that have different configurations i.e. instead of 6,9,12 all have longer subdial stems (not sure of the correct terminology) to accommodate the module for the transfer of gears from 12 oclock position to the 3 oclock position.

What this means is, if you try and put the module mentioned above onto a standard 6,9,12 7750 the subdial stems at 9 oclock and 6 oclock will be too short, and when the dial is placed on top of the movement the sub dial stems, dont 'stick out' far enough to attach the sub dial hands.

so unfortunately its a no go. you can over come it by replacing the sub dial stems fro the 3,6,9 movement to the 6,9,12 movement but its a big job and both movements need stripping.

The only other option is to source a 212 movement or 3,6,9 movement.

Hope this helps

What's a 212 do?

PAM212 has 2 subdials. At 9 o clock position, it's running second subdial. At 3 o clock position, it's 30 minutes counter. It has no 12 hours counter like normal 3-6-9 or 6-9-12 layout. The real deal should have a Flyback function.

I would recommend searching an Asian 7750 with 3-6-9 layout and disabling subdial at 6 o clock position (12 hours counter) or finding movement for PAM212/a few PAM Ferrari chrono. Or if you want to go high end, get the flyback movement (a few unbranded watches on eBay with flyback function for about 1500-2000USD).

I saw a 3,6,9 on ebay... Might still be there, It would alot more logical to buy that and use the other movement for something else.

Tnx Taka, learned a lot last weekend but this I didn't know

Ive just checked my records and you didnt buy a 6,9,12 from me, you bought a 3,6,9 date.

you should be able to use this for the PAM 212 and just remove the 12 hour counter

[Tom]

Ajoesmith - you are probably correct. That mechanism has been at my watchsmiths for months so I couldn't remember.

I think i'll go and get it and check that out.

It's a real quandry that I suppose most of us have at some point. Do you

a) buy another rep of the same version

try and have the mechanism fixed at a greater cost than a new rep

c) sell the case and all the bits, get a completely new rep and try and forget about the old one.

Decisions decisions....
