Introducing a new watch design to the Prospex Land collection, the ‘Tortoise’ is inspired by the popular diving watch shape nicknamed by Seiko fans as the ‘Turtle’ because of its shell-like profile.
This practical 2021 timepiece is powered by the 4R automatic calibre movement and includes a rotating compass bezel, crown at 4 o’clock for comfort with highly visible lumibrite on the dial and hands, easy to see in any light.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’
Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
