ETA 7750 movement for Pam GMT, is it possible?

As far as I know, the Pam 88 and 89 uses a A7750 movement modded to have a GMT function. Hence the sunken DW problem. Was wondering if using a Swiss ETA7750 would solve this problem or can it even be used? Any thoughts or advice on this? Thanks.

On the rep A7750 the GMT module is placed on top of the calender module. Consequently the dial is sitting higher and further away from the DW, giving the look of a sunken DW. So adding a rep GMT module on a Swiss7750 won't change anything.

I was afraid of that! Given this scenario, would you guys contemplate making a franken 89 with gen case, CG, crystal, dial and hands?

Hmmm, I can imagine this ain't gonna be cheap and you will still end up with the sunken DW and a too small magnification.

No, its not going to be cheap. :) I would have thought that the magnification would be alright with a gen crystal? Another route would be not to get the case. Just the changing of dial, hands and crystal.

With a Lello datewheel, I don't find the datewheel is an issue with my 089?

Now on a Chrono with a 7750 instead of a 7753 it is much more noticeable and a bigger (sunken datewheel) issue

Yes, your 89 looks quite good. So maybe a Lello DW should do the trick.

Absolutely agree, Lello's DWl makes all the difference, so sunken DW

is not an issue. And dluddy, the only thing to add to your overall beautiful

watch is the titanium T48 crown. 7750 stems with 1.2mm tap can be bought here

will this stem wotk directly on a T48 crown. Does it need any adapter?
