September 2026 Release
Variations
The creation captures the character of a celebrated Speedtimer design from 1972. It brings the thrill of touring to the wrist.
By giving each sub-dial a distinct finish, the legibility of the chronograph function is enhanced. Sky blue accents further improve legibility and help to evoke a sense of passing scenery.
The new case is produced using Seiko’s latest watchmaking technologies to create a classic and refined construction.
