Iridescent reflections, shimmering colours, dancing light: H. Moser & Cie. brings the Tiger’s Eye stone to life in an almost psychedelic setting, revealing its full beauty and mystery in an exclusive model available in two references. The Endeavour Tourbillon Concept Tiger’s Eye spotlights this fine natural stone in a modern yet understated and elegant interpretation. With neither logo nor indices, and an aperture at 6 o’clock to magnify the one-minute flying tourbillon, the dial of the Endeavour Tourbillon Concept Tiger’s Eye provides the stone with a blank canvas to express its aesthetic power.

Tiger’s Eye is a variety of microcrystalline quartz. This semi-precious stone is formed of amosite, the fibres of which are partially replaced with silica following a natural transformation process known as “pseudomorphosis”. It is these fibres, laid down in fine layers, that cause the iridescent effects which seem to bring this stone to life. Tiger’s Eye – with its mysterious name and mesmerising colours – comes in many different varieties, ranging in colour from grey-blue to golden brown to reddish brown. The blue variety of the stone, whose colour comes from veins of fibrous crocidolite and silica, is known as Falcon’s Eye. When the natural stone takes on a red hue, it is called Ox’s Eye.

This model is powered by the calibre HMC 804 movement. A marvel of ingenuity, this self-winding Manufacture 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 and the effect of friction reduced, significantly improving accuracy and isochronism in continual pursuit of perfection.

Fascinating, almost hypnotic, the Endeavour Tourbillon Concept Tiger’s Eye catches the gaze, drawing it into the reflections which mirror the eyes of the big cat whose name it bears.
