Seamaster Aqua Terra 150M Hand Wound 49.2 XXL Small Seconds Orange

In Context

At 49.2 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 53 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

231.53.49.10.06.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey matte dial with a orange gold case.

Hand-wound movement based on Unitas 6498; bridges redesigned. It is identical to 2201 apart from its slightly different finish.
