In Context
At 42.5 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 14.5 mm it is a tall case, and it will catch on a cuff. 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. 120 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. 44 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.
IW3233-07 is one of 11 executions of the IW3233 base reference. Underneath they are the same watch; what separates this one is a black dial and a rose gold case. Introduced in 1955.

Inside: Caliber 80110
Explore this caliber →The Ingenieur movement, built for shock and magnetism rather than thinness. Its distinguishing feature is an integrated jointed-arm shock absorber carrying the whole movement inside the case, on top of the usual balance-staff shock protection, and it is specified to withstand magnetic fields to 80,000 A/m. Pellaton automatic winding, quick-set date and a stop-seconds mechanism complete it.
