Omega Seamaster Two Tone Master Coaxial Chronometer 231.20.42.21.08.001 Boxed
This watch was purchased off the forum this past fall. Omega serviced this watch in September 2023. All the papers and original case materials are included. There is one link removed from the original band. The link is included, but the securing pin for the link is not present. The watch was purchased as “LNIB” and is not far off that description, having only been worn a few times. The watch has a gold bezel and gold links in the bracelet. It retails for around $17,000.
Offered here at $8500 plus shipping.

Description
This classic yet robust timepiece represents a tribute to OMEGA’s rich maritime heritage. The dramatic and easily recognisable dial design of the OMEGA Seamaster Aqua Terra 150M collection recalls the wooden decks of luxury sailboats.
This model features a sun-brushed and lacquered champagne dial decorated with the Teak Concept pattern and a date window at 3 o'clock. A scratch-resistant sapphire crystal protects this unique dial.
The 18K red gold bezel is mounted on a 41.5 mm stainless steel casebody and presented on a stainless steel and 18K yellow gold bracelet. This certified chronometer is powered by the OMEGA Master Co-Axial calibre 8500, which is resistant to magnetic fields greater than 15,000 gauss and can be seen through the transparent caseback.
