What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's design, with specific mentions of its beautiful ice blue sundial and compact 39mm case size, which some note wears smaller than its specifications due to a short lug-to-lug distance. Reviewers highlight its racing-inspired aesthetic and versatility, with one owner finding the 39mm solar model a sturdy and reliable everyday watch with 100m water resistance. However, some owners question the value proposition, citing the $700 price for a solar quartz model and a thickness of 13mm, while others expressed a preference for automatic movements. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER's attractive vintage-inspired design and compact wearability, though some debate its value and thickness for a solar quartz chronograph.

Studio Underd0g Watermelon (Gen3)

Owners widely praise the Studio Underd0g Watermelon (Gen3) for its fun, entrepreneurial, and affordable nature, with a design described as "Bauhaus meets Bugs Bunny." However, some find its colors a love-it-or-hate-it feature and others perceive the overall quality and finishing as a tier below comparable watches. Accuracy figures are not specified, but one owner found the watch too thick for their taste. The chronograph function has been noted as potentially sticky or jumpy. On balance, owners are divided on the Studio Underd0g Watermelon (Gen3), with opinions split between its unique design and perceived value for money.
