Seiko V192

Seiko caliber V192 is a solar-powered quartz chronograph movement manufactured in Japan. It maintains accuracy within ±15 seconds per month and uses an MT920 rechargeable capacitor (part number 302324D), providing up to six months of power reserve when fully charged. The movement features a power reserve indicator displayed at the 7 o'clock position, which uses the 60-minute chronograph hand to show remaining charge. The caliber remains in production.
