The stainless steel case diameter of this Tudor Biwan 1958 model 7939A1A0NU-0003 is 39mm, thickness 11.7mm, and ear distance 47.8mm, perfectly inheriting the series consistent compact proportion, comfortable to wear, and has a retro charm. The case combines polishing and matte brushing techniques, paired with a stainless steel unidirectional rotating bezel, embedded with anodized aluminum rings, adorned with red triangular markings and curved numbers along the outer ring contour, making it highly recognizable. The redesigned screw locking crown is flush with the middle shell, featuring the embossed Tudor rose logo and a waterproof depth of 200 meters. Paired with an arched sapphire crystal mirror, it combines practicality and texture.
The dial adopts a matte black arched design, paired with three-dimensional hour markers and classic hands from the Biwan series. Like other upgraded models, the dial text is simplified into two lines, and the pointer base is slightly narrowed in design. The classic lollipop second hand is preserved, echoing the design language of Tudor s early diving watches. The layout without date display ensures a simple and symmetrical dial, with clear and intuitive reading.
The movement is equipped with the domestically produced MT5400-U automatic winding mechanical movement from TUDOR, featuring 27 gemstones and a bi-directional winding design. It has been certified by the METAS Master Observatory and COSC Swiss Observatory, and has a power reserve of up to 65 hours. This movement can withstand magnetic field interference up to 15000 Gauss, and according to METAS standards, the daily error is controlled within 0/ B5 seconds. It is equipped with a variable inertia balance wheel, non-magnetic silicon hairspring, and stop second function to ensure precise timekeeping and convenient operation.
This model is equipped with a rubber strap and an Emperor T-fit clasp. In the upgraded Blue Bay 1958 series, this configuration breaks free from the details of the retro bracelet and presents a simpler and more modern wearing experience. At the same time, it retains the same quick adjustment system as the bracelet model, balancing comfort and practicality. It is a masterpiece of diving watches that perfectly integrates retro and modern elements.
