Omega Speedmaster Tri Calendar 3523.80

Omega Speedmaster Triple Calendar – Ref. 3523.30 | Automatic Chronograph | Circa 1990s

Available now at OmniWatch & Co, this vintage Omega Speedmaster Triple Calendar 3523.30, stands out as one of the most distinctive and functional pieces from Omega’s 1990s era. Combining the robust design of the Speedmaster line with the added complexity of a triple calendar chronograph, this watch offers a rare blend of technical sophistication and timeless aesthetics.

The watch features a stainless steel case measuring 39 mm in diameter — a perfect size for daily wear while retaining the presence expected from a Speedmaster. The dial is a silver sunburst with three sub-dials: a 24-hour indicator at 9 o’clock, a 12-hour totalizer at 6, and a 30-minute counter at 12 o’clock. A discreet date window sits within the 30-minute counter, while day and month apertures are located just beneath the Omega logo at 12. The outer ring of the dial features a tachymeter scale and a red calendar date indicator, adding both functionality and visual interest.

Powering this watch is the Omega Caliber 1151, an automatic chronograph movement based on the renowned ETA 7751, offering excellent reliability and ease of service. The movement is visible through the transparent case back, showcasing Omega’s attention to detail and fine finishing.

Fitted with a stainless steel Omega bracelet, this Speedmaster wears comfortably on the wrist, and the integrated design flows seamlessly into the case for a unified look. The watch is accompanied by its original box and papers, making it even more appealing to collectors and connoisseurs of the brand.
