Aquatimer Automatic 2000 Titanium / Cronotempvs

In Context

At 45 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 20.5 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. 200 m puts it in dive-watch territory, well past anything daily wear will ask 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.

IW358003 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a titanium 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.
