Endeavour Cylindrical Tourbillon H. Moser x MB&F

The Endeavour Cylindrical Tourbillon H. Moser x MB&F is a further collaboration between the two Swiss luxury watch brands. Hours and minutes are presented on an inclined sapphire dial and the regulating organ is positioned within a rotating cage, negating the adverse effect of gravity. Housed in a 42mm stainless steel case, each variant is supplied with a bewitching fumé dial.

 

H. Moser & Cie and MB&F have recently collaborated, creating two new models, each encompassing elements from the two Swiss luxury marques. The Endeavour Cylindrical Tourbillon H. Moser x MB&F shares some of its genotype with the MB&F LM FlyingT. However, when appraising the conclusion of this working alliance, the Endeavour Cylindrical Tourbillon H. Moser x MB&F also shares some of its physical features with other Moser timepieces.

This model is equipped with the HMC 810 three-dimensional automatic Manufacture calibre. The hours and minutes are presented on an inclined sapphire dial, while a one-minute flying tourbillon is positioned above. Consistent with several other models from H. Moser & Cie, this timepiece features a choice of fumé dials.

Endeavour Cylindrical Tourbillon H. Moser × MB&F

H. Moser & Cie. has borrowed from MB&F the concept of three-dimensional movements, a strong element of the Geneva Maison’s identity, protected by a sapphire dome and featuring a one-minute flying tourbillon that rises above the main dial through a ventricular opening appearing at 12 o’clock. Benefiting from the expertise of its sister company Precision Engineering AG, H. Moser & Cie. has equipped its tourbillon with a cylindrical balance spring, the same as that developed by Precision Engineering AG for MB&F’s LM Thunderdome.

Invented in the 18th century, the cylindrical balance spring is reminiscent of a worm or corkscrew, rising perpendicularly around the upper rod of the balance staff. Commonly used in historical marine chronometers at the time, it offers the advantage of developing concentrically, and therefore geometrically, since it works perfectly along the axis of its pivots. This gives it a significant advantage over the flat balance spring, whose opposite ends tend to exert forces on the pivots, despite the Philips or Breguet terminal curves which were specifically developed to partially correct the non-concentric opening of the balance spring. Fitted with a Breguet overcoil at both attachment points, the cylindrical balance spring reduces pivot friction and greatly improves isochronism. Due to its specific shape, the cylindrical balance spring is far more difficult to produce and takes ten times longer to make than a traditional balance spring.

Another reference to MB&F’s identity lies in the tilted dials, which H. Moser & Cie. has adopted for its hour and minute subdial. This is inclined at 40° so that the owner of the watch is the only one to whom it reveals the secret of time, and mounted on a conical gear train ensuring optimal torque transmission from one plane to the other. As Edouard Meylan explains: “We have Moserized the MB&F universe by developing a sapphire subdial, which melts into the background so as to highlight the beauty of our fumé dials. And to preserve the purity and elegance of this true work of horological art, we have inscribed our logo like a watermark on the sapphire subdial, thereby underlining the personal character and intimate relationship binding it to its owner”. Available in five different versions, the Endeavour Cylindrical Tourbillon H. Moser × MB&F model comes in a steel case topped by Funky Blue, Cosmic Green, Burgundy, Off-White or Ice Blue dials, all of the fumé variety.
