Date Wheel Replacement for SMP Chrono

[sam1174]

I recently bought an Omega SMP Chrono with the new Asian Valjoux 7750 movement from Andrew. The date font isn't quite right, and the date isn't centered in the window. Otto Frei has an Omega Caliber 750 date wheel for sale, and I was wondering if anyone knew if this would work on my SMP?

I've taken the watch apart a couple of times now, so I'm pretty confident I could swap the wheel (and I found a local watchmaker who will bail me out if I get in trouble), I just don't want to waste the money on it if it won't fit.

Here's a link to the date wheel I'm thinking about purchasing.

Any advice is appreciated.

ETA7750 Wheel

The font looks good, but does it line up in the center of the date window?

I've been messing around with a new DW overlay making setup--trying to see if I can produce a passable overlay "on demand" in short runs. If you;d be willing to participate in the experiment, go ahead and buy the ofrei wheel if it doesn't work and you can provide a high quality scan, I bet can make you an overlay that will fit your existing DW and look pretty damn good.

SMP chrono have Omega 1164 caliber which is itself based on Valjoux 7750 - so you need 7750 date wheel or Omega 1164 date wheel, anything else will not do AFAIK. I don't know if it's correct font for SMP, but you can order ETA 7750 stock date wheel - "Valjoux 7750 - 2557/1 - Date Ring" from almost any online retailer, e.g. http://watchpart.co.uk/date-ring-oclock-wi...7750-p-943.html
