anglage

Anglage is a decorative finishing technique used in watchmaking and fine metalworking. It involves beveling or chamfering the edges of a component, typically on the bridges, plates, and sometimes even the edges of gears or levers. This process removes sharp, 90-degree angles and replaces them with smooth, polished slopes. The primary purpose of anglage is aesthetic, as it catches and reflects light, making the movement appear more intricate and visually appealing. Beyond its visual appeal, anglage also serves a practical function by reducing stress concentrations on the edges of the components, potentially increasing their durability.

The application of anglage is labor-intensive and requires a high level of skill. It is traditionally done by hand using specialized files and polishing tools. There are different styles of anglage, including straight anglage and serpentine anglage, which refer to the curvature of the beveled edge. The complexity and quality of the anglage are often considered indicators of the craftsmanship and quality of a timepiece. While historically a hallmark of high-end watchmaking, modern advancements have also led to CNC-machined anglage, though hand-anglage is still highly prized for its artistry. This meticulous finishing touch is a testament to the dedication to detail found in the creation of fine mechanical objects.
