A Universal Genève manufactured around the 1940s, featuring the extremely rare Cal.250 bumper automatic movement. This early screw-back waterproof model is in excellent condition with a black gilt dial. It is likely equipped with the earliest bumper automatic Cal.250 with Incabloc shock protection in Universal’s lineup. The case uses the rare 3/4 rotation screw-back waterproof design, preceding the full-rotation style, with 'Waterproof,' 'Antimagnetic,' and 'Shockabsorber' engraved on the case back, showcasing Universal’s commitment to both waterproof functionality and meticulous craftsmanship in their early automatic models. The black gilt dial, with an iridescent oil-slick sheen, and the unpolished stainless steel case further emphasize its rarity and exceptional preservation, making it truly a collector’s item.
