H. Moser & Cie. X MB&F - Endeavour Cylindrical Tourbillon

BHD 29,000.000

H. Moser & Cie. has integrated MB&F’s three-dimensional movements into a watch featuring a one-minute flying tourbillon, visible through a ventricular opening at 12 o’clock. With expertise from Precision Engineering AG, it uses a cylindrical balance spring, like in MB&F’s LM Thunderdome, enhancing isochronism and reducing pivot friction.

This spring, reminiscent of historical marine chronometers, is difficult to produce and takes ten times longer than traditional springs. The watch also features tilted, sapphire subdials inclined at 40°, revealing the time only to the wearer. Available in five versions, the Endeavour Cylindrical Tourbillon H. Moser x MB&F showcases fumé dials in various colors.
