The Omega CK 2505, affectionately known as the "Jumbo," is a standout in Omega's lineup from the mid-1940s to early 1950s, notable for its oversized 38mm case—an uncommon feature for its era. This particular example showcases a clean, Art Deco-leaning dial layout with an outer minute track, mixed Arabic numerals, and a recessed small-seconds register at 6. The dial has been professionally restored by a dial specialist using period-correct techniques, offering a pristine presentation that enhances its daily wearability. The reference 2505-21 is marked inside the caseback with "acier inoxydable" and Omega Watch Co markings, consistent with the steel, non-water-resistant dress case typical for the reference family. The Caliber 265 movement, a descendant of the 30T2 "workhorse" line, is valued for its robustness, featuring 15 jewels, 18,000 vph, and a power reserve of approximately 40–45 hours. Collectors often seek CK 2505 variants for their dial originality and condition, with a correctly executed restoration making this watch an excellent daily wearer.
