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.\u003c\/div\u003e\n\u003cdiv class=\"specifications\"\u003e\n\u003cul\u003e\n\u003cli\u003eBrand and Model: OMEGA Jumbo 38mm\u003c\/li\u003e\n\u003cli\u003eReference: 2505-21\u003c\/li\u003e\n\u003cli\u003eCase Material: Steel\u003c\/li\u003e\n\u003cli\u003eCase Size: 38mm (without crown)\u003c\/li\u003e\n\u003cli\u003eLug-to-Lug: 45mm\u003c\/li\u003e\n\u003cli\u003eThickness: 10mm\u003c\/li\u003e\n\u003cli\u003eDial: Professionally restored by a dial specialist using period-correct techniques\u003c\/li\u003e\n\u003cli\u003eCrystal: Acrylic (period-correct)\u003c\/li\u003e\n\u003cli\u003eCrown: Signed\u003c\/li\u003e\n\u003cli\u003eStrap or Bracelet: Calf leather\u003c\/li\u003e\n\u003cli\u003eMovement: Manual-wind mechanical, small seconds\u003c\/li\u003e\n\u003cli\u003eCaliber: 265 (30T2)\u003c\/li\u003e\n\u003cli\u003eJewels: 15\u003c\/li\u003e\n\u003cli\u003eMovement Serial: 1275••••\u003c\/li\u003e\n\u003cli\u003eEstimated Production: Circa 1951\u003c\/li\u003e\n\u003cli\u003eWater Resistance: Splash Water Resistant (handwashing ok, not showering)\u003c\/li\u003e\n\u003cli\u003eService Date: 02-03-2026\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch3\u003e📦 What’s Included\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBox\/Case:\u003c\/strong\u003e Secure black travel watch case.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e Invoice and our service certificate worth €369 — included free of charge\u003c\/p\u003e\n\u003ch3\u003e🚚 Shipping, Returns\u003c\/h3\u003e\n\u003cp\u003eInsured worldwide shipping. 14-day inspection (unused, seals intact).
