H. Moser & Cie caliber HMC 901 NHM

Placeholder for watches using caliber HMC 901 without the hour and minute hand. Hand-wound HMC 901 calibre Dimensions: 28.8 x 33.55 mm/height: 6.25 mm Frequency: 21,600 Vib/h 28 jewels Power reserve: minimum 87 hours Flat hairspring Double Moser stripes on the plate and bridges Movement and components hand-finished and decorated One-minute flying tourbillon at 6 o'clock with skeletonised bridge Minute repeater For the design of its thirteenth manufacture movement since 2005, H. Moser & Cie. called upon the expertise of MHC Manufactures Hautes Complications SA, the experts in minute repeaters. Together, they have performed a remarkable feat, managing to combine perfect harmony with a strong sound. The HMC 901 is a true jewel of a movement, combining a minute repeater and a tourbillon — itself a rare feat in watchmaking — inside a shaped calibre. Housed within the rectangular case of the Swiss Alp Watch Concept Glossy Black, it is equipped with two rectangular shaped gongs, which are particularly difficult to tune.
