CK2915, but this 2021 update (Ref. 310.30.42.50.01.001) pays homage to the Ref. 145.022-69 used during the Apollo missions.

CK2915, but this 2021 update (Ref. 310.30.42.50.01.001) pays homage to the Ref. 145.022-69 used during the Apollo missions. The reintroduction of the 'step dial' and 'DON' bezel 50 years after their original production signifies Omega's shift toward vintage-accurate aesthetics in their modern core collection. The Calibre 3861 movement inside is the first major mechanical upgrade to the Moonwatch in over 20 years, introducing METAS certification and high magnetism resistance (15,000 gauss) as recorded by Omega in 2021. Read full story ## COLLECTOR NOTES 1 The 2021 bracelet update features a taper from 20mm at the lugs to 15mm at the clasp, making it significantly narrower than the 18mm taper of the previous Calibre 1861 models. ## SCARCITY Common 20-40% Common Legendary Older mass-produced items still widely available. Easy to find on eBay, antique malls, and estate sales in large quantities. Rarity 2/10. Curiosa currently catalogues 20 watches items at rarity 2 or higher. ### Typical Characteristics - Mass produced historically - High survival rate - Readily available everywhere ### AUTHENTICITY CONFIDENCE Very High (88% confidence) #### Confidence Factors - Distinctive 'stepped' dial transition is crisp and consistent with factory tolerances - High-fidelity printing of the 'Professional' text and sub-dial graduations matches Calibre 3861 benchmarks - Bracelet taper and clasp proportions are correct for this specific modern reference [How does authenticity detection work?](/fake-art-detection) ## WATCHMAKER'S ASSESSMENT Vintage Watchmaker & Horology Specialist Horologist Identification is high due to the presence of multiple reference-specific traits (step dial, all-brushed bracelet, printed logo) that align perfectly with the modern 3861 hesalite model specifications. ### KEY EVIDENCE - 1 Correct teardrop counterweight on the chronograph seconds hand for the 3861 reference - 2 Step dial present with clearly defined indentation at the minute track - 3 Printed (not applied) Omega logo indicates the hesalite (Ref .001) variant - 4 All-brushed bracelet links correctly correspond to the hesalite model specifications - 5 Dot-Over-Ninety (DON) bezel alignment is factory-correct ### WHAT WOULD IMPROVE CERTAINTY - → Check the clasp for the micro-adjustment button introduced in 2022-2023 batches - → Verify the laser-etched Omega symbol in the center of the hesalite crystal under 10x magnification - → Request view of the Calibre 3861 movement to confirm the serial number matches the lug engraving COLLECTOR GLOSSARY (3 terms) ## CONDITION & GRADE Excellent (90-95%) ### Grading breakdown Dial and hands are pristine with contemporary white luminova; indices show no discoloration. Small hairline surface scratches localized on the hesalite crystal are removable with PolyWatch, a standard trait of this reference. ### Condition The tachymeter bezel shows no impact marks or loss of black anodization. Bracelet links show no visible stretch, and the case edges remain sharp with original factory brushing intact on the lug tops. ## WATCH MARKET VALUE $4,500 - $5,800 Updated: May 11, 2026 How we estimate value ### Who buys this A mix of first-time luxury watch buyers seeking the definitive chronograph and experienced enthusiasts who prefer the hesalite variant for its historical accuracy. ### What increases value - • Presence of original warranty cards and pictograms - • Balance of factory warranty (5 years from original purchase) - • Unpolished case condition with sharp 'box' edges on the lugs ### What lowers value - • Deep scratches or cracks in the hesalite crystal requiring full replacement - • Missing bracelet links which can cost $50-$100 per link to replace ### What makes top-tier examples - • Newer batches featuring the updated 'tool-less' micro-adjustment clasp - • Full set documented by a reputable Authorized Dealer ### Grade & condition Bezel alignment, click-spring tension of pushers, and depth of the sapphire caseback etching (on other models). ### Rarity & demand Common High demand Sells quickly [Browse similar watches objects](/archive/watches) For informational purposes only, not a formal appraisal. ## FROM THE CABINET OF [BA ](/cabinet/bas365) [ ### Bas365 ](/cabinet/bas365) Wonderseeker • 4 items [View Full Cabinet](/cabinet/bas365) ### COMMENTS No comments yet.
