FAQs

How often should I have my Seamaster serviced?

It is generally recommended to have the watch serviced every 5-7 years to ensure optimal performance and water resistance.

Is the watch water-resistant if the crown is not screwed down?

No, the watch is only water-resistant when the crown is fully screwed down.

What type of battery does the watch use?

The OMEGA Seamaster Diver 300M is a self-winding automatic watch and does not use a battery.

Can I replace the bracelet with a different strap?

Yes, you can replace the bracelet with a variety of straps. However, it is recommended that you use a strap designed for the watch for the best fit and water resistance.

What is the helium escape valve for?

The helium escape valve is designed to release helium that may enter the watch during saturation diving, preventing the crystal from popping off during decompression.

Pull the crown to the second position (farthest out) and rotate to set the time.

How do I set the date?

Pull the crown to the first position (one click out) and rotate to set the date.
