Manufactured around 1940, this Universal Genève timepiece features the highly rare Caliber 250 and boasts a bumper automatic movement. It's an early model screw-back waterproof watch with a black dial, in excellent condition. This Universal timepiece is likely equipped with one of the earliest forms of shock protection, the Incabloc, and utilizes the bumper-style automatic winding Caliber 250. The case is also distinctive, adopting a rare 3/4 screw-back waterproof design rather than a fully rotating one. The case back is engraved with 'Waterproof,' 'Antimagnetic,' and 'Shockabsorber,' showcasing Universal's strong dedication and craftsmanship towards creating early automatic models with waterproof functionality. With its iridescent rainbow-hued oil film on the black gilt dial and a non-polished stainless steel case, the exceptional rarity and superb preservation of this watch make it a true collector's item.
