Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsStudio Underd0g The Gimlet

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.

Studio Underd0g The Gimlet is praised for its playful, layered dial construction featuring a textured sapphire disc over a luminous base, creating depth and animation, and its comfortable 38mm case dimensions. Owners note its attractive dial color and combination, though some find the design too similar to other models and question the aesthetic of the visible dial screws. The watch utilizes a reliable, tactile Sellita SW210-1 manual-wind movement. On balance, owners and reviewers rate Studio Underd0g The Gimlet highly for its unique dial construction and comfortable wearability.
