Seiko Prospex Sea Watch, S23631J1

Seiko Prospex S23631J1 Diver's Watch, 1000 m

The Seiko Prospex S23631J1 wristwatch is designed for demanding use both on land and underwater. The watch's titanium case is lightweight yet extremely durable, and the one-piece shell construction adds structural strength under high pressure. Water resistance to 1,000 meters means that the model is reliably suitable for water sports and saturation diving. The unidirectional rotating bezel, screw-lock crown, and clear black dial support safe time tracking both during the day and while diving.

Seiko's 7C46 caliber quartz movement is renowned for its reliability and accuracy. The long battery life of approximately five years makes this wristwatch worry-free to use. The sapphire crystal of the S23631J1 is also highly scratch-resistant, and the LumiBrite-coated hands, indexes, and bezel ensure good readability in low light conditions, including underwater. The black silicone strap fits securely on the wrist and works well even over a wetsuit.

Japanese Seiko watches are known for their technical excellence and durability. With over 100 years of history, Seiko has brought significant innovations to the watch industry, such as the first quartz watch and kinetic technology. Seiko watches combine timeless elegance with first-class product development.
