What makes the Bohen Mille Mer an Exceptional Watch?

1st Watch equipped with an internal date magnifier :

A date magnifier is a magnification system intended to enlarge the date numerals.


For the Bohen Mille Mer, I wanted something impossible: combining a curved glass and a magnifying dates lens. Normally, it is not possible because a date lens needs to be glued on a flat glass.

Therefore, I developed an innovating device unprecedented in the watchmaking world: a lens connected by two bridges to a titanium ring, placed between the sapphire dome and the hands. This innovation required numerous long-term resistance calculations and extreme adjustment precision. To Bohen, engineering is not just a question of movement. Everything is done to achieve excellence.

Currently the only diver 1.000m with crown at 12 o'clock:


From my aknowledgement, only two other watches offer this option in the world. But these models are not 1000 meters waterproof.

A vertical crown offers great wearing comfort and a beautiful elegance of design.





Counter-slope dial.


Dials with counter-sloping edges (edges downwards inclined) are generally found on luxury watch models. They give a magnificent effect of depth but they are too bulky to fit into a diving watch. We have studied this issue and we have found a solution. So, our counter-slope dial brings the unique touch that gives a strong identity to our watches.

Multiple Treatments .


For the watchcase, we apply three different surface treatments, not counting the backcase engraved by deep machining. The movement has premium settings and a high-end finish.


There is a lot of work in a Bohen Watch.
