Yema Sous-Marine 55.18.52

1971 Yema Diving Watch in Stainless Steel with 37 mm Case & Rotating Bezel

Purpose-built yet wearable, the Sous-Marine presents compact proportions at 37 mm with a 40 mm lug-to-lug span for balanced wrist presence. The stainless-steel case carries clean chamfers and a practical, tall bezel whose clear graduations favor at-a-glance timing. Under the acrylic crystal, the dial architecture prioritizes legibility with luminous markers and a decisive minute track. An 18 mm lug gauge (period-correct for early-’70s divers) invites rubber or leather straps, preserving the piece’s authentic tool-watch character while remaining versatile for daily wear.
