Important facts

The Omega Seamaster Diver 300M 210.30.42.20.03.001 has a screw-down crown which ensures a much better water resistance by providing a tighter seal between the crown and the case. This keeps moisture or dust from entering the watch case, which could otherwise cause damage to the movement. This also helps to prevent accidental adjustment of the time or date. The screw-down feature makes it more difficult for the crown to be accidentally turned, reducing the risk of incorrect timekeeping. Also, it is a reassuring feel to tighten the crown by screwing it down.

This watch has a sapphire crystal which provides a durable and clear viewing surface for the dial. This type of crystal is highly resistant to scratches and does not discolor over time.
