This Speedtimer stands out with its bold white and black styling, but its story runs deeper. Released as part of Seiko’s 110th Anniversary of watchmaking, it pays tribute to the brand’s long history of precision and innovation. It fits right into a busy lifestyle with clear subdials, responsive hammer-style pushers, and a curved sapphire crystal that stays legible on the go. The stainless steel bracelet balances a secure fit with comfortable flexibility. Solar-powered and limited in production, it’s a piece that delivers both practical function and collector appeal.
