⚠ BEFORE YOU BUY — PLEASE CHECK
• Caliber 7T92 does not have an alarm function. This model provides timekeeping, date and chronograph functions.
• Stopwatch 1/20-second hand behaviour. After the stopwatch is started, the 1/20-second hand runs for about 10 minutes and then automatically stops at the "0" position; it moves again when measurement is stopped or split time is taken.
• Water resistance is 100 m (10 ATM). Suitable for swimming and general water contact; not rated for scuba diving.
• Instruction booklet provided. The packaging contains a SEIKO instruction booklet.
• The same model number may be produced in different factories depending on production date, so minor differences in design or box may occur. The country of manufacture is therefore not stated.
• Battery is consumable. Battery life is rated at approximately 3 years and will be shorter if the stopwatch is used more than 2 hours per day.
