Seamaster Aqua Terra 150M Co-Axial 43 GMT Chronograph Stainless Steel / Red Gold / Grey / Bracelet

In Context

At 43 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 150 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 60 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

231.20.43.52.06.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a red gold, stainless steel case. Beyond the time it carries a chronograph and a gmt.

Self-winding chronograph movement with GMT/second time zone function, column wheel mechanism and Co-Axial Escapement for greater precision, stability and durability of the movement. Silicon balance spring on free sprung-balance, twin barrels mounted in series, automatic winding in both directions to reduce winding time. Central hour, minute and chronograph seconds hands, small seconds and GMT hands, and 12-hour and 60-minute recorders. Rhodium plated finish with Geneva waves in arabesque. "Si14" is engraved on the arm of the balance wheel.
