Seiko 5 Sports Watch SRPJ45

The Seiko 5 Sports SRPJ45 pays tribute to the iconic Seiko Time Sonar watches of the 1970s, combining vintage inspiration with modern Seiko 5 Sports engineering. This unique timepiece features a translucent sea-green (turquoise) dial that reveals the movement of the day-date disc, creating a distinctive skeleton-style effect reminiscent of the original Time Sonar design.

Housed in the signature SKX-inspired case, the watch features a bi-color unidirectional rotating bezel, bold luminous hands and markers, and a striking red-orange seconds hand that enhances its retro character.
