Term Definition
Annual Calendar 

An issue with watches showing dates is that one has to make date adjustments every other month because of the varied 30/31 day length of the months. An annual calendar is smart enough to factor for this automatically, requiring only one adjustment for February. See also: Perpetual Calendar.

Anglage

A movement finishing technique whereby the edges of the component is filed and smoothened at a 45-degree angle. Often found in high-end movements.
