H. Moser & Cie. Endeavour Concept Minute Repeater Tourbillon Aqua Blue

With the Endeavour Concept Minute Repeater Tourbillon Aqua Blue, H. Moser & Cie. presents one of the most traditional and romantic watch complications and combines it with a magnificent flying tourbillon.

Drawing attention to the minute repeater mechanism, it has taken the bold decision to position the two shaped gongs and the hammers on the dial side, in a brand-new design. This involved overcoming many technical challenges. In particular, the chimes had to be curved so as not to interfere with the flying tourbillon and keep the design understated.

The H. Moser & Cie. Endeavour Concept Minute Repeater Tourbillon Aqua Blue watch features a 40 mm diameter case in red gold or titanium. This specially designed case architecture optimizes the sound and achieves the perfect balance between volume, resonance and harmony. The case middle has been widened to the maximum in order to accommodate the movement while allowing enough space to create a soundbox.

This amplifies the chiming of hours, quarter-hours and minutes by two gongs, onto which fall two hammers that are raised based on information provided by different feeler-spindles.

The Endeavour Concept Minute Repeater Tourbillon Aqua Blue has been designed to retain classic, perfectly balanced dimensions and proportions.

At six o’clock, the one-minute flying tourbillon is visible behind a skeletonised bridge. Boldly contemporary, the tourbillon appears to float weightlessly above the “Grand Feu” enamel dial.

Starting with a pattern engrained onto a gold base, as if hammered, four different colour pigments are washed, finely crushed, then applied to create an ombré effect. It took approximately one hour of careful work for the master enameller to painstakingly apply the pigments, adding them one by one so that the colours oxidise and meld together when heated in the furnace, without any pixellation. A translucent “Grand Feu” enamel dial must be fired twelve times in total to create the signature H. Moser & Cie. fumé effect.

Each dial is unique and has a particularly striking texture and an intense Aqua Blue hue. The watch dial comes with no logo or indices. The magnificent HMC 904 hand-wound calibre can be admired through the sapphire crystal case back.
