Omega Seamaster Aqua Terra 150M Master Co-Axial Chronometer Blue Teak Dial Stainless Steel 41.5mm MINT CONDITION COMPLETE SET 231.10.42.21.03.003

Price On Request

Wooden yacht decks gave this dial its vertical grooves, and one turn under the light explains why sailors loved the look first. Blue this deep reads almost black across a boardroom table and lights up like open water the moment you step outside. Steel sports watches that dress up without trying are rare, and collectors tend to stop here.

Presents itself in mint condition with little to no signs of wear. Sun-brushed and lacquered in rich blue, the dial carries Omega’s Teak Concept pattern in subtle vertical grooves that catch the light one row at a time. Carved from stainless steel with signature lyre lugs, the case pairs mirror-polished bevels against soft-brushed flanks that flash at every angle. Behind a pane of sapphire, the caseback reveals a rotor with wave striping and red lettering, a second face as impressive as the first.

Functions include hours, minutes, seconds, and date. Power comes from the Master Co-Axial Calibre 8500, a self-winding movement with a Co-Axial escapement, free-sprung balance, and 2 barrels holding a 60-hour reserve. Certified as a chronometer, it resists magnetic fields over 15,000 gauss. Unscrew the crown on the right, wind about 30 turns in the first position, then pull to the third position to stop the seconds and set the time. Push back to the middle position and advance the hour hand until the date reaches the day before today, then keep going until the date and hour line up correctly, before screwing the crown down securely to seal it to 150 meters.

Comes as a full set, boxed with warranty documentation.

Ask a room full of Omega collectors which Aqua Terra they would actually wear, and the argument usually lands on the one from before the redesign. Half a millimeter wider, out of production, and rarely surfacing in this state, this is the generation that argument is about. Reach out before it moves.
