【Description】 Among the world-renowned Omega Speedmaster series, this is a distinguished model equipped with complex functions—the Speedmaster Triple Date Ref.3523.80. Its deep blue dial combines a triple calendar function displaying the day, month, and date with a chronograph, making it a high-spec model. The intelligent yet sporty design makes it attractive not only as a collectible but also as a highly practical watch. This piece was overhauled in May 2025 by a certified first-class watchmaker and is currently running with excellent accuracy, showing an average daily rate of +1 second. While there are some minor scratches and wear from use, the overall condition is very good, and the watch can be worn immediately. The crystal, case, and bracelet remain beautiful with no major damage. The genuine Omega box shows slight deterioration, but the set is complete with inner box, outer box, instruction manual, and two extra bracelet links, making it highly desirable for collectors. With the presence unique to the Speedmaster and excellent practicality, this watch is suitable for both daily wear and special occasions. It is also highly attractive from an investment perspective. I have taken many photos from various angles so that you can fully evaluate the watch. Please take a close look at the pictures to ensure your satisfaction. 【Specifications】 ・Brand: Omega ・Model: Speedmaster Triple Date ・Reference number: 3523.80 ・Movement: Automatic (chronograph, day-date-month triple calendar) ・Case material: Stainless steel ・Bracelet: Genuine stainless steel bracelet (with 2 extra links included) 【Size】 ・Case diameter: approx. 39 mm (excluding crown) ・Wrist circumference: approx. 17 cm (can be extended to approx. 19 cm with the extra 2 links) 【Condition】 This watch was overhauled in May 2025 by a certified first-class watchmaker and is currently keeping time very well with a daily gain of about +1 second.
