The famous Heritage Black Bay series ushered in the first Tudor-made chronograph watch, equipped with an automatic movement, column wheel and vertical chronograph clutch wheel device.

   Since the introduction of Prince Oysterdate, the first chronograph in 1970, Tudor has been making watches that are closely linked to the racing world. The same goes for the diving world. Since 1954, Tudor has continuously improved the quality of its professional diving watches. The newly launched Hybrid Black Bay Chrono boldly combines the tradition of diving watches represented by the Biwan series with the essence of racing chronographs. Qi Cheng Biwan Chronograph retains the famous snowflake feature of the Biwan series, the ‘Snowflake’ hands. Since 1969, the ‘Snowflake’ pointer has been a trademark of the brand. Against the domed matte black dial, ideal results are achieved when reading. The counter chronograph is hollow and has a sharp contrast. The calendar window is set at 6 o’clock. The 41 mm diameter steel case retains the distinctive features of the Biwan collection, and the design of its buttons is inspired by the first generation of Tudor chronographs. The rounded brushed steel fixed bezel is engraved with the tachymeter scale, which makes the appearance of this new sports chronograph perfect.
Tudor manufacture chronograph movement MT5813

   The Tudor-made chronograph movement MT5813, which powers the chronograph Bichen Chronograph, is deserved of a high-performance movement with a proud 70-hour power reserve, silicon hairspring, and certification from the Swiss Precision Timepiece Testing Center. It is crafted in purely traditional watchmaking, with a column wheel and a vertical timing clutch wheel. Adhering to the quality concept of Tudor, this movement is sturdy, reliable and extraordinary. To ensure the quality of the watch, all Tudor products pass a series of rigorous tests.
Denim style jacquard textured strap

   The textured strap is one of the signature features of the Qi Cheng series, and Tudor is also one of the earliest brands to use the textured strap. This strap is made by a 150-year-old family-owned company in the St-Etienne region. It is woven from a 19th-century jacquard loom for high quality and comfortable wearing. The Qicheng Biwan timing model launched this time is matched with a dark blue denim wind strap, designed by Tudor, and then commissioned by the above-mentioned family business. Each Qicheng Biwan Chronograph comes with a denim wind strap, and two other strap designs are available. A steel strap inspired by the discounted riveted straps that come with the watches produced by Tudor in the 1950s and 1960s. The links on both sides of the strap are connected by rivet heads, and the structure is stepped. These design features are famous worldwide. Both aesthetic details appear on a strap at the same time, while the solid links create a modern structure. The other is a dark brown belt with a discount.
Source of inspiration for the Biwan Collection

   The Tudor Kai Cheng Biwan Chronograph is based on the historical tradition of the Tudor watch. It combines the past characteristics and perfectly integrates ancient and modern times. The overall shape, dome-shaped dial and mirror of the new model inherit the design essence of the first Tudor diving watch. The eye-catching winding crown is derived from the ‘Big Crown’ model (model 7924) introduced by Tudor in 1958, the first Tudor watch to be water-resistant to 200 meters (660 feet). In addition, the ‘snowflake’ hands on the dial are unique and angular, borrowing from the classic style of providing watches for the French Navy in the 1970s.
Kai Cheng Series
   Speaking of the main characteristics of the Tudor Kai Cheng series, I have to mention its unique creative process: reinterpret the brand classics, eclectic and freely play. The first result was the TUDOR Heritage Chrono, launched in 2010, a reinterpretation of the first TUDOR chronograph that appeared in 1970. Since then, some of the most important masterpieces in Tudor history have been reborn with a new attitude in the Kai Cheng series. This series of watches is not simply a classic replica, but a fusion of traditional aesthetic characteristics and contemporary watchmaking technology. Biwan, as the outstanding series of Tudor Kai Cheng watches, embodies Tudor’s more than 60 years of diving watch making experience, which can be described as the perfect example of the classic design of the brand.
