Abstract
The protecting device comprises a transparent sapphire plate. The trade-mark of the watch and a digital indication are applied on the reverse side of that plate. These indications are applied by vaporization under vacuum. The digital indication is introduced in an index by the watch manufacturer and forms part of a code permitting the individualization of the watches produced and to identify them at all time. Said plate is indissolubly glued onto the sapphire glass of the watch so that said indications are sandwiched between these two pieces. The individualization of the product, that this protecting device permits, constitutes for the purchaser of the watch the guarantee that the indication designating the origin of the watch is genuine.
