Omega Seamaster Aqua Terra co-axial chronometer ref. 231.10.42.21.06.001. 2025 service by Omega certified watchmaker. Grey teak-pattern dial on original bracelet. A classic, classy, robust, and practical piece that represents a tribute to Omega's rich maritime heritage.
Calibre 8500 automatic co-axial chronometer. 60 hour power reserve. 150m / 500ft water resistance. Transparent caseback; sapphire crystals. Keeping time within spec.
41.5mm, 20mm lug
Though the watch has not been a safe-queen, it is still in good condition. I had a sympathetic polish performed during service, so on wrist the watch is very presentable. However, up close and under loupe it does show some scratches and minor imperfections. The dial and hands are excellent. The grey “Skyfall” type dial has a sunburst effect and really pops in direct light.
Sold on original bracelet sized for my ~7 inch wrist. 2 extra links included. No box or papers, though original owner’s purchase receipt is included. Watch will ship in a black generic padded case.
Asking $4299 + insured shipping via FlagShip. F2F in the London area also possible.
Positive feedback here on CWC and references available if required. Please do not hesitate to ask further questions or request additional photos. Cheers!
