For the third year in a row, in addition to the 18 sponsoring watchmaking maisons, the upcoming SIHH watch salon in Geneva will assemble a host of independent, artisan brands in its Carré des Horlogers; at 17 participants, this year’s Carré des Horologers promises to be the largest to date. Also for the third year running, one of these indie watchmakers, Schaffhausen-based H. Moser & Cie., will introduce one of its extremely limited, über-minimalist Concept pieces at the show. Here’s what you need to know about this year’s release, the Endeavour Tourbillon Concept.

The watch ? limited to just 20 pieces worldwide, like its predecessor, 2017’s Endeavour Centrer Seconds Concept Cosmic Green ? continues the tradition of the Concept pieces, inaugurated in 2016 with the Endeavour Perpetual Calendar Concept, by eliminating nearly every element from the dial except the hands, including the brand logo and any kind of hour markers. The dial is in Moser’s now-recognizable Funky Blue fumé style, with radiating color shades and a sunburst finish that imparts a “smoky” look. The presence of leaf-shaped hour and minute hands ? made from 18k white gold, like the three-part, 41-mm-diameter case ? are another hallmark of Moser watches. The main talking point, of course, is at 6 o’clock: a large flying tourbillon, equipped with a skeletonized bridge, that appears to float above the dial’s iridescent surface.
