The Seiko 8222A is a dependable and efficient quartz analog movement that emphasizes accuracy, simplicity, and ease of use. Produced during the 1980s and 1990s, the 8222A is part of Seiko’s extensive range of quartz calibers designed to power everyday wristwatches. Its straightforward design focuses on delivering precise timekeeping alongside a practical date display, making it a popular choice for both casual and formal watches.
Caliber Number: 8222A
Movement Type: Quartz (Analog)
Display:
Hours, minutes, and seconds hands
Date window positioned typically at 3 o’clock
Accuracy: Approximately ±20 seconds per month
Battery Type: SR927W (1.55V silver oxide)
Battery Life: Approximately 2 to 3 years
Jewels: None (electronic quartz movement)
Crown Positions:
Position 0: Normal operation
Position 1: Date adjustment
Position 2: Time adjustment
Powered by a quartz crystal oscillator, the 8222A offers precise and stable timekeeping, typically deviating no more than ±20 seconds per month. This level of accuracy meets the needs of daily wear with minimal adjustments.
The movement includes a date complication shown in a window on the dial, usually at 3 o’clock. The date is quick-settable via the crown, allowing easy manual correction without altering the current time.
Using an SR927W silver oxide battery, the 8222A operates efficiently to provide a battery life of two to three years, minimizing the need for frequent battery replacements.
Pull the crown out to the second click (Position 2).
Rotate the crown clockwise or counterclockwise to adjust the hour and minute hands to the desired time.
Push the crown back to Position 0 to restart normal timekeeping.
Pull the crown out to the first click (Position 1).
Rotate the crown clockwise to change the date incrementally.
Avoid adjusting the date manually between 9 PM and 2 AM, to prevent damage to the date-change mechanism.
Push the crown back to Position 0 after adjustment.
Replace the battery with an SR927W silver oxide cell when power declines or the watch stops.
Typical battery life spans from 2 to 3 years, depending on usage and conditions.
Professional battery replacement is advised to preserve water resistance and case integrity.
No specific reset procedure is generally required after battery change, but time and date settings must be verified.
The quartz electronic movement requires no lubrication or mechanical servicing.
Avoid exposure to strong magnetic fields, shocks, and extreme temperatures to protect accuracy and internal components.
Clean the watch regularly, especially after exposure to moisture, sweat, or dust.
For water-resistant models, have water resistance tested periodically.
The 8222A movement powered numerous Seiko watches, particularly:
Entry-level to mid-range quartz models during the 1980s and 1990s.
Watches designed for practical daily use with clear analog time and date display.
Classic, understated designs emphasizing durability and reliability.
