To set the time, unscrew the crown and pull it out to the second click. Rotate the crown to adjust the hour and minute hands. Push the crown back in and ensure it's screwed tightly to maintain water resistance.
Regularly clean the watch with a soft cloth and rinse it with fresh water after exposure to saltwater. It's recommended to have a professional service every 3-5 years to ensure water resistance and movement accuracy.
Inaccurate timekeeping could be due to low battery or magnetization. Replace the battery if low, and demagnetize the watch with a professional tool. If issues persist, consult a certified watch technician.
The Seiko H855 Diver's Watch is water-resistant up to 200 meters, making it suitable for recreational scuba diving but not for saturation diving.
To replace the battery, ensure the watch is in a dry environment. Remove the case back with a proper tool, replace the old battery with a new one, and reseal the case back to maintain water resistance. Consider professional service to avoid damage.
Although the watch is water-resistant, it's not recommended to wear it while showering due to potential exposure to heat and soap, which can deteriorate the seals and compromise water resistance.
If the crown is difficult to unscrew, try gently applying a small amount of lubricant to the threads. If it remains stuck, do not force it; instead, seek assistance from a professional watch technician to avoid damage.
The bezel is used to track elapsed time. Align the zero marker with the minute hand at the start of a dive or event. As time passes, the minute hand indicates the elapsed time on the bezel.
Store the watch in a cool, dry place away from magnetic fields. If not in use for a long period, consider removing the battery to prevent leakage. Keep it in a watch box or pouch to protect it from dust and scratches.
Check for a serial number on the case back and match it with official Seiko records. Examine the watch for quality craftsmanship, and purchase from authorized dealers to ensure authenticity.
