H. Moser & Cie Endeavour Concept Minute Repeater Tourbillon (Electric Blue, titanium)
H. Moser first showed this watch in 2019 in white gold with a black dial, and in 2021 brought it back in titanium with Electric Blue, a new colour for the brand, in a sunburst without Moser's usual fumé gradient. In keeping with the Concept line there is no logo and no index, so the dial holds only the flying tourbillon at 6 o'clock and the minute repeater's hammers and gongs, which Moser moved to the dial side with the help of the specialist Timeless SA. The gongs had to be curved and kept on one level to clear the tourbillon. Oracle of Time notes the case middle is widened into a soundbox, where titanium's resonance helps the chime carry. The hand-wound HMC 903 runs for 90 hours, the case is 43 mm by 14 mm, and it was limited to 20 pieces at CHF 330,000. Moser no longer lists it.
