Radiomir 1/8 Second

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. 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.

PAM00246 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. It was a limited edition.

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