Yema Sous-Marine 55.18.52

The tall, clearly graduated rotating bezel gives this Yema Sous-Marine watch from 1971, reference 55.18.52, its purposeful outline. A 37 mm stainless steel case, clean chamfers and luminous dial markers preserve its practical diving design. Automatic caliber FE-4612 powers the watch, which retains original components and the carefully preserved case geometry of this used example.

Rotating bezel, luminous markers and acrylic crystal

The bezel’s clear graduations provide a readily visible timing scale around the dial. Its height contributes to the case profile, while the clean chamfers give the steel outline definition. Beneath the acrylic crystal, luminous hour markers and a decisive minute track keep the display focused on legibility.

Those features express the Sous-Marine’s historical diving-watch design. The bezel and dial provide separate timing and time-reading surfaces, each with clear graduations.

Compact case and automatic FE-4612

The case measures 37 mm across and 40 mm from lug to lug. Its relatively short span contains the watch’s reach across the wrist, while the 18 mm lug width supplies the fitting dimension for a compatible rubber or leather strap. The steel case and tall bezel give this diving watch its practical visual character.

The FE-4612 powers this automatic watch. Wrist motion winds the movement during wear, making self-winding operation a useful everyday characteristic of this model. The watch is fully serviced and fully operational.

Preserved components and warranty

This used example retains its original watch components, preserved case geometry and period details. It comes with a 12-month warranty, without box or papers. The rotating bezel, acrylic crystal and compact steel case remain the specific features that define its early-1970s presentation.
