H. Moser & Cie. Endeavour Tourbillon Concept Cosmic Green

The tourbillon, a complex mechanism with both technical and aesthetic appeal, has been revisited by H. Moser & Cie., highlighting its very essence: a fumé dial, dressed in the finest Cosmic Green, two leaf-shaped hands for the hours and minutes, and, at 6 o’clock, a one minute flying tourbillon produced in module form.

This design, the power of which is reinforced by the absence of both logo and indices on the dial, accentuates the visual impact of the tourbillon. It is an ode to simplicity where only the essential remains: 100% traditional Swiss watchmaking, resolutely contemporary and utterly seductive.

The dial on the Endeavour Tourbillon Concept Cosmic Green is completely streamlined, with a minimalist beauty enhancing this fascinating colour. At 6 o’clock, the flying tourbillon is simply eye-catching. Appearing to float weightlessly, it deservedly takes centre stage. By giving the timepiece back its primary function, H. Moser & Cie. proposes a return to the essential, to authenticity, proving that true luxury is unmistakeable, even without a logo. The Endeavour Tourbillon Concept is a timepiece with a powerful aesthetic.

Visible behind the skeletonised bridge of the one-minute tourbillon beats the HMC 804 automatic calibre, designed, developed and produced entirely by H. Moser & Cie. Powering this movement with a three-day power reserve, the oscillating weight transfers the energy to the barrel via a bi-directional pawl winding system which reduces the time required to fully wind the watch. The oscillating weight is skeletonised, revealing the mechanism beneath.

A marvel of ingenuity, this movement is equipped with a double flat hairspring designed and produced in-house. Thanks to this pair of matched hairsprings, the movement of the point of gravity on each spring when it expands is corrected, significantly improving accuracy and isochronism in continual pursuit of perfection. In addition, the paired hairsprings also reduce the effect of friction normally experienced with a single hairspring, improving isochronism. Finally, the tourbillon’s unique design makes it an interchangeable module, assembled and regulated independently of the movement via a simple plug and play system which allows for easy servicing.

This limited edition of just 50 white gold pieces will be on sale from February 2019.
