Perlage is a very advanced decorative technique used on the movement plates of a watch. Very fine, round designs, done by engraving or machining, are impressed into this metal. These look like fine parallel lines or rosette design done to enhance the beauty of the movement through these patterns, which tell a story of craftsmanship and attention to detail.
Pearling adds an aesthetic but also evokes precision and elegance as a characteristic of the movement, making it a favorite ornament in the realm of high watchmaking. This technique seems to exaggerate the effect of light on shade so that the movement assumes a dynamic and refined look that is usually admired even by watch enthusiasts and collectors.
