Exclusive Shop Models Expressing Individuality Are Also a Great Choice!

Produced by Yoshikage Kajiwara, former Creative Director at Beams and representative of the creative consulting firm LOWERCASE, these are solar-powered dive watches that are a compact, town-use adaptation of the 1975 Seiko dive watch featuring an external protector.

Like the models released at the end of last year, the case size is a boy-sized 42.7mm diameter. This iteration features colorways that can be enjoyed in a more genderless manner than ever before.

Despite their compact size, they are packed with high dive watch specifications, including 200-meter water resistance for saturation diving, solar charging functionality that eliminates battery replacement concerns, and silicone straps that resist degradation from saltwater and sweat.

In addition to the regular models, the lineup includes the "LOWERCASE 2019 Limited Edition," a limited production model of 1200 pieces with a black base accented by striking rose gold and red details, evoking the character of vintage items. Furthermore, collaborations with select shops such as United Arrows, EDIFICE, and Journal Standard offer items that will stand out in spring and summer wardrobes.
