H. Moser & Cie. Endeavour Tourbillon Concept Limited Edition

With this new timepiece, the Schaffhausen-based Manufacture revisits the traditional tourbillon complication with a minimalistic but luxurious dial featuring the brand’s signature fumé, two blued hands, and at 6 o’clock and a one minute flying tourbillon produced in module form.

Presented at SIHH 2018, the Endeavour Tourbillon Concept with a steel case features a design of very rare power, reinforced by the absence of both logo and indices on the dial. What is striking about the appearance of the Endeavour Tourbillon Concept is its dial; by featuring neither logo nor indices, the details can be admired to best effect. The colour, that famous fumé which has become the H. Moser signature, extends in subtle nuances in gradually deepening shades, with the different shades emphasised by the “sunburst” pattern. The eye-catching flying tourbillon positioned at 6 o’clock appears to float weightlessly. The hours and minutes hands are faceted and blued, as is the tradition.

The Endeavour Tourbillon Concept is encased in steel. Behind the skeleton bridge of the minute tourbillon is the latest addition to movements designed, developed and produced by H. Moser & Cie.; the HMC 804 self-winding calibre. 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 to reveal 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 easy servicing.
