Omega Chronomètre 30T2 RG SC – 18K Yellow Gold, Factory Oxidized Case (Circa 1945)
The Omega Chronomètre 30T2 RG SC in solid 18K yellow gold is one of the finest examples of mid-century precision and timeless restraint. Produced around 1945 and preserved in remarkable condition, this chronometer-grade wristwatch captures the essence of Omega’s golden age—where understated beauty met horological mastery.
The Case – Golden Patina of Time
The 33 mm 18K yellow gold case reveals a stunning, naturally oxidized surface developed over decades of careful storage in a vault. This gentle oxidation is not a flaw but a signature of authenticity and minimal wear—a tangible link to its untouched history. The solid case remains crisp and well-proportioned, with elegant lugs that balance refinement and presence.
The Omega-signed crown remains intact, completing the case’s original integrity.
The Movement – The Legendary 30T2 RG SC
At its heart lies Omega’s manual-wound Calibre 30T2 SC RG—one of the most celebrated chronometer movements of the 1940s. Revered for its accuracy, finishing, and reliability, the 30T2 RG SC represents the pinnacle of Omega’s pre–Co-Axial chronometer tradition.
This rare “SC” (Seconde Centrale) version features a central seconds hand, an uncommon configuration among chronometer 30T2s.
The movement bears serial number 10,403,890, dating its production to circa 1945, perfectly aligning with the case serial 10,691,074.
The Dial – Untouched Silver Beauty
The dial is an absolute marvel—factory original, unrestored, and wonderfully preserved. Executed in solid 925 silver (“Argent”), it is signed by the famed dial maker ZJ, whose work for Omega remains highly sought after by collectors.
Applied Roman numerals and a raised enamel minute track bring depth and elegance, while a subtle, even patina imbues the surface with vintage charm.
The blued central seconds hand adds a vibrant, mesmerizing contrast, animating the silver dial with every tick.
Many examples of this reference have undergone refinishing over the years; this untouched original dial—stamped with the back engraving “23 396”—commands a premium in both rarity and desirability.
The Strap & Details
Paired with a hand-made Belgian leather strap, the watch balances artisanal craftsmanship with period-correct authenticity. The gold-plated Omega buckle completes the ensemble, offering a finishing touch of vintage sophistication.
Protection is provided by a classic plexiglass crystal, true to the era.
