Ingenieur Automatic AMG Black Series Ceramic

In Context

At 46 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. 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.

IW3225-03 is one of 2 executions of the IW3225 base reference. Underneath they are the same watch; what separates this one is a black dial and a titanium, ceramic case.

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.
