Yema Sous-Marine, 631014
A gently domed acrylic crystal sits above the high-contrast dial of this Yema Sous-Marine watch from 1969, reference 631014. Bold luminous plots and a clear minute track preserve the purposeful design of this diving watch, while the chrome-plated case measures 38 mm across with a short 39 mm lug span. The manually wound FE 140-1 movement completes this carefully preserved example.
High-contrast dial under arched acrylic
The bold lume plots and clean minute track organise the dial for clear reading. A gently arched acrylic crystal gives the display its softer, curved profile and moderates reflections. The combination retains the practical emphasis of the Sous-Marine design.
Compact case and hand-wound FE 140-1
The chrome-plated case keeps its original geometry and period character. Its 38 mm diameter is paired with a notably short 39 mm lug-to-lug span, while the 18 mm lug width supplies the fitting measurement for a compatible strap. The exterior finish is chrome plating.
The FE 140-1 powers this manually wound watch. Crown winding is part of its operation, alongside the straightforward time display. This watch is fully serviced and fully operational.
Preservation and historical diving design
Made in 1969, this Sous-Marine retains the clarity and functional simplicity of its late-sixties diving design. Its diving classification refers to the model’s historical design.
