Tudor watch quality

Tudor watches insist on excellence and strive to improve product quality. One of the results is that the new Biwan ceramic watch has successfully obtained the precision timepiece certification of the Master Observatory. This is the first time a Tudor watch has received this certification, and it requires several modifications to the original Tudor watch movement. This also means that Tudor watches are not afraid of any test, and can further ensure the excellent quality of Tudor watches by obtaining the certification of this independent authority.

Fully certified by an independent body to ensure compliance with high standards
The Swiss Federal Institute of Metrology (METAS) Master Chronometer Certification covers a wide range of content and comprehensively examines a number of important performances of watches, including travel time accuracy, anti-magnetic ability, waterproof performance and power reserve. The certification requirements are particularly strict, and accurate travel time is the primary consideration. The certification requires that the average daily travel time error of a watch should not exceed 5 seconds (0+5), which is further reduced by 5 seconds compared with the daily average error standard (-4 +6) of the Swiss official observatory certification (COSC) for a single movement. seconds, which is 1 second less than Tudor’s general internal standard (-2 +4) for brand original movements. The certification also requires the watch to maintain accurate travel time in a high magnetic field environment of 15,000 Gauss. In addition, the waterproof performance and power reserve of each master chronometer certified watch must comply with the International Organization for Standardization (ISO) 22810:2010 standard. Before obtaining this certification, the watch needs to meet two prerequisites: the watch is made in Switzerland and meets Swiss manufacturing standards; the movement must be certified by the Swiss Official Observatory (COSC).

high-tech style
The Tudor Biwan ceramic watch cleverly combines the brand's classic aesthetics with modern high-tech details, showing a unique style. The one-piece matte black ceramic case is sandblasted and contrasts sharply with the mirror-polished chamfered edges for a striking silhouette. The embedded rotating word circle is also made of black ceramic material, decorated with sun light effect. The same-tone matte scale engraved on it complements the texture of the outer ring, subtly responding to changes in light, bringing a rich visual experience. The dial is also black, and is ingeniously matched with off-white luminous coating three-dimensional hour markers, making the contrast even more eye-catching and charming. The strap is also black, of course, and the leather and rubber composite strap is decorated with a "snowflake" pattern on the inside and equipped with discounts; the black textured strap that comes with the watch is decorated with cream stripes, adding the finishing touch to the mysterious black appearance pen.

Tudor watch original movement MT5602-1U
The Biwan ceramic watch is equipped with the original Tudor watch movement MT5602-1U, which has the display function of hours, minutes and seconds. The movement adopts the classic finish of the original Tudor movement, but the whole body is deep black, which echoes the overall design of the watch and highlights its excellent performance. The one-piece black hollow tungsten automatic oscillating weight is frosted with sandblasted details, and the splint and main splint are interlaced with polished and sandblasted finishes, embellished with laser decoration.

The movement is equipped with a non-magnetic silicon hairspring, and the inertia fine-tuning balance wheel is fixed on both sides with a strong horizontal splint to ensure stability and accuracy, and the travel time error is only within 5 seconds (0+5).

Another notable feature of the original Tudor movement MT5602-1U is its 70-hour power reserve certified by the Swiss Federal Institute of Metrology (METAS), which allows the wearer to have "no worries on weekends". In other words, if you take off your watch on Friday night, you only need to put it on your wrist to use it normally on Monday morning, without needing to rewind and adjust. Give it "working time" and return "rest time" to yourself.

The essence of Biwan type
Like other models in the Black Bay series, the Black Bay ceramic watch follows one of the iconic features of Tudor diving watches-the sharp-edged "snowflake" pointer, which appeared in the brand's 1969 product catalog. The Biwan series cleverly combines the brand's traditional aesthetics with contemporary watchmaking craftsmanship. This series of watches is not simply a replica of classic watches, but embodies the essence of Tudor's diving watch production for nearly 70 years, and it still occupies a place in the watch industry today. The new watch is more integrated into the neo-retro design style, and has an outstanding performance higher than the industry standard in terms of craftsmanship, precision and reliability, durability and detail finishing.
