The Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited Edition is praised for its retro design, balanced 42mm case, good finishing, and sapphire crystal. It is powered by the calibre 8R48, featuring a column wheel and vertical clutch, and offers 100m water resistance. Some find its 45-hour power reserve short compared to modern alternatives, and the date window placement is a point of discussion. The solar-powered variant is noted for its compact proportions and character, though some desire thinner cases and improved bracelet micro-adjustment. Overall, owners and reviewers appreciate the SPEEDTIMER's vintage-inspired aesthetics and solid build, with critiques focusing on power reserve and minor functional details.

A reviewer notes the Miyota 8s25 automatic movement has a 40-hour power reserve and its unidirectional winding rotor may wobble. Overall, owners appreciate the Vario NAVI Single Hand Compass for its refreshingly different take and casual time-telling dial.
