Description
The Speedmaster Calibre 321 Chronograph 39.7 mm is a tribute to the iconic heritage of the Speedmaster collection, blending vintage design with exceptional craftsmanship. This model boasts a polished stainless steel case, measuring a refined 39.7 mm in diameter, inspired by the original Speedmaster from 1957. The black step dial, featuring classic chronograph counters and a white tachymeter scale on the black ceramic bezel, provides both elegance and functionality. At its heart lies the meticulously recreated Calibre 321, a manual-winding movement cherished by collectors for its role in moon legacy. Finished with a domed sapphire crystal and transparent caseback to view the intricately finished movement, this timepiece is a seamless blend of historical charm and modern precision. Unworn and in like-new condition, this watch comes with its original box, documents, and a warranty dated 2024.
