Breakdown of costs:
Rep: $275
Genuine AR-coated crystal: $200
Genuine bracelet: $200
Relume: $100 (?)
ETA 7750 movement and installation: $250
Genuine hands: $50
total: $1075 (all figures are estimates)
The caseback will still be the same etc.
You also have no warranty, same re-sale value, water resistance, quality control, and genuine Omega movement. A few dollars more and you can get a used genuine in stainless steel
I'm not trying to put off the modders though!
My point is appreciate the unmodded version for what it is, improving that is not really economically viable
