B1348 F4 produces the DiTu Bi Bay bronze M79250BM wristwatch.

【Case】The watch size is 43 millimeters. As a pioneer in bronze materials, meticulous attention is paid to every detail. The 【aluminum bronze】 material used is perfectly suitable—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, thus 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】A upgraded movement is used, eliminating the awkward situation of empty date positions. When classicism reignites, the D'Arco Bronze Biwan M79250BM continues to write a new legend, with its time-tested quality. The robust nature of the Biwan series serves as a declaration of style when worn on the wrist, and also a tribute to vintage aesthetics. The aluminum bronze material is fully replicated from the original version; over time, it develops a unique copper color. Every trace becomes a memory of your time, making the watch a companion on your journey to success.
