"41mm black, stainless steel

Unique "Sashe Circle" design: The double-color rotating bezel is a major highlight. The anodized aluminum bezel is filled with golden numerals on the surface, and the brown background half-circle represents the daytime 12 hours, while the black background half-circle represents the nighttime time. This black and brown color combination design is very similar to the color scheme of Sashe soda, and is called "Sashe Circle", full of fun and recognizability.
Precise original movement: Equipped with the original movement MT5652 developed by Tudor specifically for the Blue湾 Greenwich Gold Steel Watch， it is equipped with non-magnetic silicon hairspring and is certified by the Swiss Official Observatory (COSC)， with an accuracy exceeding the certification standard. The daily error is between -2 and +4 seconds， and the power reserve is approximately 70 hours.
Characteristic "Snowflake" hands： The "Snowflake" hands have been a major design feature of Tudor diving watches since their inception in 1969. This watch also adopts this design， with both the hour markers and hands coated with A-grade Swiss Super-LumiNova® night light coating， making it easy to read the time at night.
Inlay gold material and retro style： Made of stainless steel and gold， i.e.， "inlay gold" material， it combines the toughness of stainless steel with the luxury of gold. The strap is inspired by the folding rivet watch straps manufactured in the 1950s to 1960s， with the chain links on both sides connected by rivet heads， presenting a unique stepped structure， with a strong retro feel.
Three-time zone display function： It has the ability to read three-time zones. The thinner pointer indicates the departure time， and the shorter "Snowflake" pointer indicates the local time， and it has an independent time adjustment function. The time of the third time zone is indicated jointly by the 24-hour scale double-rotating outer ring and the "24-hour" pointer， which is clear and easy to read， convenient for travelers to use.
