This watch shape is known as a ‘Tortoise,’ inspired by the popular diving watch shape nicknamed by Seiko fans as the ‘Turtle’ because of its shell-like profile.
Powered by the 4R35 Automatic movement, with 200m water resistance, highly visible indices and screw-down crown at 4 o’clock, this resilient timepiece is designed for stylish practicality.
Seiko Prospex watches are designed for sports lovers and adventure seekers in the water, in the sky or on land – and are robust for everyday wear, whatever the environment.
Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
