The Cal. HMC342.502 movement developed in-house and used exclusively by Moser is a hand-wound movement with true bevel wheels, which ensure the gentle, low-wear operation of the winding system. The Moser tooth system with its optimized efficiency in the entire wheel train guarantees optimal torque in the escapement module and an associated long service life. The date can be adjusted via the patented Double Pull Crown mechanism, which permits reliable setting of the position with the crown. Also typical of Moser is the arrangement of the fourth wheel and the third wheel beneath a common bridge. The value of this exclusive movement is underlined visually by screwed gold mounts and the Moser ground stripes.
