Ingenieur Automatic 35 Stainless Steel / Black

In Context

At 35.1 mm it is classically proportioned: the size a dress watch was understood to be for most of the twentieth century, and small enough to sit under a cuff. At 10.7 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, 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. 42 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.

IW3249-06 is one of 3 executions of the IW3249 base reference. Underneath they are the same watch; what separates this one is a black guilloche dial and a stainless steel case. Introduced in 2025.

Self-winding movement with central seconds and date; power reserve 42 hours. TOtal of 151 components including 23 jewels.
