Anglage, also known as chamfering or beveling, is a meticulous finishing technique used in watchmaking to enhance the aesthetic appeal and craftsmanship of a timepiece. This process involves the careful filing and polishing of the edges of watch components, such as bridges, plates, and other movement parts, to create a smooth, angled surface. The primary purpose of anglage is to eliminate sharp edges, which not only improves the visual elegance of the watch but also reduces the risk of damage to other components during assembly and operation.

The art of anglage requires a high level of skill and precision, often performed by hand using specialized tools. The craftsman meticulously files the edges at a precise angle, typically 45 degrees, and then polishes them to achieve a mirror-like finish. This labor-intensive process is a hallmark of high-end watchmaking, reflecting the dedication to detail and quality.

Anglage is not only a testament to the watchmaker's expertise but also a sign of luxury and exclusivity. It is often visible through transparent case backs, allowing watch enthusiasts to appreciate the intricate work. The presence of anglage in a watch movement is a clear indicator of superior craftsmanship and is highly valued by collectors and connoisseurs.
