honestly, if you are going to buy all the parts and pay someone to do it for you, I'd just buy a used gen.
The PO franken is already borderline too expensive in the rep vs gen scale. Adding build expenses would put it over the top for me.
Here's a breakdown of the parts from Ofrei
Name SKU Each Total
Omega Dial For Caliber 2500 OME-2500-DIAL#3 ................................ $242.00
Genuine Omega Cal 2500 Hour & Minute Hands Silver Arrow With Luminous HAN-4150 ................................$38.00
Genuine Omega Cal 2500 Second Hand Silver Arrow Luminous With Red Tip HAN-4151 ................................$17.60
Omega Stainless Steel Crown 42184 8100/3905W ................................$38.00
Omega Case Tube 090ST1232 OME-090ST1232 ................................$6.60
Omega Sapphire Crystal 062SB3063 OME-SB3063 ................................$169.00
Omega Bezel 082SU1703 OME-082SU1703 ................................$228.00
Sub Total $739.20
Shipping would be from $15 to $33 on the parts alone.
UPO $260
So you are talking about more than $1,000.00 for the parts (considering you don't care about the HE valve. That would add $75 to the bill).
Now add builder costs, time, shipping to and from builder and this project would cost close
$1300.
Considering you can find used gens for $1800-$2000, I don't really think paying to get a franken built would be a good deal.
I've built mine myself and I did not add the bezel (bought a new gen before getting there).
