The new collection of Moser watches is manufactured by a company with a horological tradition going back for more than 175 years. Characteristics that have become established over such a long period can be recognized in both historic and modern Moser watches. The medallion that is internationally registered as the company’s trade mark, which is regarded in collectors’ circles as the most reliable indication of the authenticity of a Moser watch, can also be found in today’s watches. The fourth wheel and the third wheel of all movements produced by Moser are arranged beneath a bridge with the distinctive convex form around the jewel bearings. Both features are also present, together with the movement number, in modern Moser calibres. A rare speciality in watchmaking is the bright-polished, white, rather than blued, screws used by Moser to secure the gold mount on the bridge. To ensure that today’s wristwatches remain as slim as possible, however, the screws for the gold mount are now screwed down flush with the bridge. The execution of the escape wheels and pallet forks in solid gold also has historical predecessors with Moser. Whereas gold in the past had to be hammered meticulously by hand, the running surfaces today are hardened in a process patented by Moser in order to minimize wear and friction.
