This Omega watch, manufactured around the 1940s, is equipped with the Cal. 23.4SC movement and features the rare "Neptune hands." The Neptune hands are inspired by the trident of Neptune, the ancient Roman god of the sea, making this an exceptionally rare piece.
The blue steel Neptune hands beautifully complement the champagne dial, which features a stunning design with a white railroad track and Roman numeral indices arranged in a roulette-like layout. The case back, engraved with "MODELE + DEPOSE / WATERPROOF," shares the same waterproof construction as the 33.3 chronographs of the same era.
This early screw-back waterproof case is also noteworthy for its rare thin profile. It is a remarkable example of Omega's distinctive design, color harmony, and quality from this period. The watch is in excellent overall condition, with a subtle iridescent sheen across the entire dial, enhancing its appeal as a highly collectible piece.
