Omega Seamaster Aqua Terra Co-Axial Chronometer 150M 38.5MM
Black dial
Ref. 231.10.39.21.01.001 (same as Skyfall except black dial instead of blue)
Excellent condition, only 6 months old
Under warranty until September 2023.
Purchased as NOS on September 28, 2018 from authenticwatches.com.
I believe this is one of the very last produced examples of Omega Seamaster AT 8500 in 38.5mm.
The warranty card is in my name but can be transferred to the new owner for a $50 nominal fee.
I upgraded the butterfly clasp and had the center links polished. I explained the process and reasoning behind this upgrade in this thread:

In terms of accuracy, the last time I checked (about 2 months ago) it gained only 1 second in 72 hours, which is pretty amazing, but let’s just consider that this watch runs within COSC spec.
A face to face transaction in San Diego would be ideal.
Asking price: $2,990
