Snailing is a decorative finishing technique used in watchmaking, characterized by a pattern of circular spirals arranged in one or more bands. This technique is a form of abrasive finish and a type of graining. To achieve the snailing effect, watchmakers use a small rotating tube with an abrasive edge, which is applied off-center to the component. The part being decorated also rotates in the opposite direction, creating the distinctive spiral pattern. This intricate process adds a textured and visually appealing element to watch components, often seen on parts like ratchet wheels and barrels. The snailing finish not only enhances the aesthetic appeal of a watch but also reflects the craftsmanship and attention to detail inherent in high-quality watchmaking.
