Oil sink

Oil sink

Oil sink, also known as an oil basin or oil tank, is a concave or hollow area located within a mechanical watch movement. It plays a crucial role in preserving and distributing lubricating oil to the essential components of the movement, including gears, bearings, and the escapement mechanism, which require proper lubrication to reduce friction and wear, ensuring smooth operation of the watch movement.

The reservoirs are strategically placed in areas that are prone to friction. Skilled watchmakers meticulously apply the appropriate lubricating oil to the oil reservoirs during assembly, ensuring reliable and smooth operation of the watch over time.
