Important facts

The Seiko Prospex S23631J1 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. Sapphire is also resistant to most chemicals and less likely to shatter compared to other materials, making it a safer choice for the watch wearer. Thefore sapphire is a good choice for high-end wristwatches. It is of course an expensive option, compared to other materials, like plexiglass.

This timepiece is a dive watch, meaning it was designed and built specifically for underwater use. All dive watches need to have water resistance of at least 20 bar / 200 meters, legibility in low-light conditions, a timing feature (e.g.: rotating bezel), running indicator and corrosion resistance.
