AI-assisted summary
Description from the seller
Brand: Omega.
Model: Omega Speedmaster Day-Date "Triple Calendar"
Reference number: 3521.30
Movement: Automatic
Case material: Solid stainless steel characterized by the unmistakable alternating finishes of brushed sides and mirror-polished surfaces on the lyre-style twisted lugs. The circular case is topped by a fixed, sloping, mirror-finished steel bezel bearing the externally engraved and printed black tachymeter scale. The crown at 3 o'clock is a custom, knurled push-pull crown with the official Ω logo, flanked by the two traditional cylindrical smooth chronograph pushers. On the left side, discreetly positioned at 10 o'clock, is a semi-embedded quick-set button for advancing the day of the week. The case back is sealed by a solid stainless steel screw-down back bearing the brand logo finely engraved in relief at the center.
Dial color: White-silvery. The three-counter layout showcases the "Triple Calendar" complication, with the central silvered baton hand with a crescent tip indicating the day of the month. Inside the sub-dial at 12 for the chronograph minutes, two symmetrical rectangular windows open to indicate the day of the week and the current month. The sub-dial at 9 o'clock co-axially houses the small seconds and the 24-hour indication. The sub-dial at 6 o'clock functions as the chronograph hours counter. The dial is punctuated by slender geometric baton hour markers in polished steel and completed by faceted, polished baton hands. At 3 o'clock the applied Ω logo sits beside the printed mark "OMEGA/Speedmaster/AUTOMATIC".
Case diameter: 38 mm
Crystal: Domed sapphire crystal with high scratch and abrasion resistance, anti-reflective treatment.
Strap material: Original Omega bracelet in solid stainless steel featuring a refined sporty and flexible five-row parallelogram-link design with brushed finish and polished intermediate links.
Strap color: Silver steel.
Strap length: Approximately 19 cm
Clasp: Deployant folding clasp, monobloc with a satin outer plate.
Clasp material: Stainless steel with the official brand name deeply engraved and the Ω logo above.
Comes with standard box and no warranty.
Shipping: Tracked and insured with DHL
Any customs duties are the buyer's responsibility.
