Functional laser marking for part identification and traceability as well as engravings for design purposes are indispensable in the watch industry. While one engraved mechanically or etched in the past, more and more laser machines are now being used for marking tasks. Part numbers, serial numbers and/or charge labeling, as well as data matrix codes, but also decorative markings such as logos and graphics, are applied to watch parts, e.g. clockwork components, oscillation weights, bezels, crowns, housings, watch case backs or dials by means of laser marking. The advantage of the laser here is clearly the high precision so that even the smallest and filigree laser markings can be carried out efficiently, quickly and with high precision on wristwatches.
