Miyota 5R32

The Miyota 5R32 is a quartz movement manufactured in Japan by Miyota, the watchmaking division of Citizen. It measures 2mm in height with no jewels and delivers an accuracy of ±20 seconds per month. The caliber is a three-hand movement with sweep seconds and offers a two-year battery life. Miyota officially recommends the 5R32 for women's size watches, though Philip Stein notably used two 5R32 calibers in a men's watch model.
