Seiko Prospex SPEEDTIMER Seiko Brand 100th Anniversary SPEEDTIMER Limited EditionvsTissot PRX

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.

The Tissot PRX is widely praised for its exceptional finishing, comfortable wearability, and strong value proposition, with owners and reviewers highlighting its luxurious feel for the price. The integrated bracelet, often noted for its shine, finishing, and brushed surfaces with polished edges, is a significant draw, as is the watch's neo-vintage aesthetic and refined dial pattern. The slim case profile, measuring around 10.5mm to 11mm depending on the source, contributes to its comfortable daily wear, and the 100m water resistance is a practical feature. While one owner reported specific issues with a PRX Chronograph's hands and quality control after service, other sources focus on the Powermatic 80's reliable automatic movement and the overall joy of wearing the Tissot PRX. Some find sizing the bracelet challenging due to the lack of a micro-adjustment option.
