Geophysic 1958 Platinum

In Context

At 38.5 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 11.3 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, 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. 40 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.

800652J stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a stainless steel case. It was a limited edition. Introduced in 1958.

Mechanical automatic winding movement, 201 parts, 28,800 vibrations per hour, 43-hour power-reserve.
