Radiomir Regatta 1/8th Second Titanium

In Context

At 47 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. 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. 100 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.

PAM00343 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a titanium case. It was a limited edition.

Foudroyante split-seconds movement based on a a LaJoux-Perret modification of the 7750.
