Setup, Compatibility & Care
To set the time and date, unscrew the crown until it pops out to the first position for date adjustment and the second position for time setting; always screw the crown back down fully to maintain water resistance. To ensure long-term care, rinse the watch with fresh water after exposure to salt water to prevent mineral buildup. Avoid using harsh chemicals or abrasive brushes on the dial or casing. Regularly inspect the crown seal to ensure it remains tight, and consider a professional service every 3 to 5 years to keep the Powermatic 80 movement calibrated correctly.
