Century-Old Vintage OMEGA (c. 1924) – Rare Caliber 23.7 S T2 | Fully Serviced! Main Description: Offered for sale is an exceptional, century-old men's Omega timepiece. This is a rare find for horological history enthusiasts, collectors, and anyone seeking a unique, fully functional antique watch for their wrist. Inside the watch beats a rare, original, and highly sought-after manual-wind Omega movement—caliber 23.7 S T2 (the caliber designation is clearly stamped on the plate beneath the balance wheel, as shown in the attached macro photo). The movement's serial number is 6,709,188; according to official Omega records, this places the production of this century-old "heart" around 1923–1925. The "T2" (Transformation 2) designation indicates the second, technically refined generation of this esteemed movement. The watch has undergone a complete, professional service by a watchmaker (cleaning, oiling, and precision adjustment). The movement runs very well and consistently, and the balance operates correctly. You are purchasing a timepiece that is 100% technically sound and ready to wear, requiring no further financial outlay (the cost of such a service for a vintage movement is typically several hundred zlotys). Details and Condition: • Movement: Original, 15-jewel Omega Caliber 23.7 S T2 from the 1920s. Bridges and screws preserved in excellent condition; clean and free of damage. • Dial: 100% original and unrestored, featuring a beautiful, authentic patina that highlights the piece's age. It displays a mix of Arabic numerals and arrow markers—characteristic of the military/retro era—along with a sub-seconds dial at the 6 o'clock position. The classic OMEGA inscription appears below the 12 o'clock marker. • Hands: Original, iconic "Syringe" or "Alpha" style hands, crafted from heat-blued steel (shimmering beautifully in the light). • Case: Classic, round period-correct design (mid-size/boysize, typical of the era). Made of brass/base metal alloy, originally featuring a thick gold plating. It shows natural, honest signs of wear—such as rubbing of the gold plating on the edges and lugs—which lends the watch an incredible vintage character. • Case back: Smooth on the outside; the interior features a factory-applied perlage finish. • Crystal: New, replaced during servicing (classic Hesalite/Plexiglass perfectly suited to the style of the era). • Strap: New black leather "Bund" style strap with a protective pad. It beautifully complements the watch's style, while the pad effectively protects the case from direct contact with the skin. Summary: This watch represents a fascinating combination of a rare, century-old Omega movement and a dial featuring retro/military styling. Thanks to its recent servicing, excellent timekeeping, and the unique nature of the 23.7 S T2 caliber, this watch represents a great investment—prices for such pieces on the vintage market are steadily rising.
