Citizen 3510

The Citizen caliber 3510 is a Japanese quartz movement with 12 jewels, operating at 32,768 Hz with an accuracy of approximately 15 seconds per month. It uses an SR927W battery providing around 24 months of power and features a chronograph controlled by three pushers, plus an alarm function activated via a switch at the 3:00 position. A distinctive characteristic is the coil spring connecting the alarm's piezoelectric device to the caseback—a small component that can be lost during battery changes. The caliber was used in Breitling watches, making it notable among Japanese movements found in Swiss luxury timepieces.
