Aquatimer Automatic 2000 Titanium / Black / Blue Lume / Rubber / Los Roques

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 20 mm it is very tall, and sits high off the wrist. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 2000 m is a professional diving rating, far past any demand a wrist is likely to make of it.

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.

IW3580-04 is one of 2 executions of the IW3580 base reference. Underneath they are the same watch; what separates this one is a black dial and a titanium case. It was a limited edition. Introduced in 2017.

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.
