B025 – MARS PROJECT ONE Titanium Case Dual Time Zone (Earth and MARS) Automatic Wristwatch. In year 2021, with various countries’ space department space projects reaching and exploring MARS, BEHRENS decided to tribute these human’s space projects by developing our own space project.

B025 – MARS Project ONE is an automatic wristwatch constructed base on a highly re-polished and re-decorated Swiss Cal.SW200 automatic wind movement as a power source, from which on top we have developed a unique mechanism (mechanical module) that allow the watch to accurately display an Earth & MARS dual time system completely developed in-house.

The uniqueness of this model is that time in ‘Hours’ & ‘Minutes’ are displayed by 4 rollers system (for Earth & MARS Hours & Minutes) driven by the intergraded mechanical module. Also featuring with the week of Earth & MARS (left and right), Date (center), the 2 globes to display the time zone for Earth & MARS covered by domed crystal cased by a rectangular titanium case sized 42mm in width and measure 50mm lugs to lugs.


MARS – Project ONE automatic wristwatch is featuring with a mechanical Earth / MARS Dual Time Zone intergraded module system completely developed in-house. Both time-zones are in 24-hours base and displayed by a 4-rollers system. From which MARS time per day is 24:37 equivalent to Earth time, from which we have mechanically adjusted the speed of the MARS time display to run in a 24-hour basis, meaning while the MARS time synconized with Earth time by the 4-rollers, the time to complete MARS 24:37 is being displayed by 24:00.

The 2 globes are representing Earth & MARS time zone which rotate daily. There will also be day of the week displays for both MARS & Earth and as well a date display in the center. On both sides of the titanium case, there are 2 display windows to see the globes with time reference printed on crystal.
