B1351 F4 produces the Di Tuo Bi Bay bronze M79250BM wristwatch.

【Case】The watch measures 43 millimeters. As a pioneer in bronze materials, it emphasizes meticulous detail. The [aluminum bronze] material used is perfectly suited—its oxidation process is slow, and it does not produce green rust; moreover, it has higher hardness and greater weight—ensuring that the watch retains its authentic appearance after oxidation, preserving its unique style. 【Bracelet Clasp】The hand-stitched Italian cowhide material is treated with a matte finish, enhancing the vintage look, and pairs perfectly with the aluminum bronze clasp. 【Movement】It uses an upgraded movement, eliminating the awkward situation of empty date positions. When classicism reignites, the Dirti Bronze Biwan M79250BM continues to write a new legend, shaped by time. The robust features of the Biwan series serve as a declaration of style when worn on the wrist, while also paying tribute to vintage aesthetics. The aluminum bronze material is fully replicated from the original; over time, it develops a unique copper color, and every trace becomes a mark of your time. Let the watch become your partner on the path to success.
