Seiko SRPA21K1 Prospex Padi Automatic Special Edition Watch
Greater security is achieved by positioning the screw-lock crown at the 4 o'clock position.
The dial design has just one objective; maximum legibility, even deep in the ocean where sunlight does not penetrate. The hour markers are large, so as to allow the maximum surface area and depth for Seiko's Lumibrite coating.
The crown and power reserve buttons have screw-down protection to prevent any accidental operation.
