Seiko has crafted the perfect dive companions which functionality, heritage and style
The vast oceans cover over 70 per cent of our planet, yet we have only scratched the surface of their depths. Scuba diving opens a door into this hypnotising underwater world, playing a crucial role in scientific discovery, marine preservation and comprehension of aquatic ecosystems that exist on our planet. Passionate divers become modern-day explorers, encountering vibrant marine life and uncovering the ocean’s many secrets.
On such pursuits, a reliable wristwatch is indispensable. When you dive into a new world exploring the ocean, you leave all the noise above and you enter a place where it’s easy to lose track of time. Dive watches are made to withstand extreme pressures from deep waters and allow divers to keep accurate timing when submerged. Top-notch examples come from Seiko’s renowned Prospex series, which has long combined sturdiness with innovation and style. Water resistance, luminous markers and rotating bezels make these watches dependable companions during arduous underwater voyages.

Luminous markers and hands ensure visibility in the dimmest underwater conditions, and with 200 metres of water resistance, this piece is designed for serious diving. The SPB439J1 seamlessly blends vintage charm with modern technology, making it a distinguished choice for divers and watch enthusiasts alike.
