What people say

Owners + reviewers, side by side

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

Lum-Tec Eclipse

Owners widely praise the Lum-Tec Eclipse for its comfortable, slim profile and thin wearability, with specific commendations for its beautiful dial, good readability, and bracelet design. The knurling on the crown is also noted as a positive feature. Some owners express concern over the 42mm case size and find the dial's font and indices unappealing, though others appreciate the deep-dish slant. One owner notes a slight gap where the lugs meet the bracelet. The Lum-Tec Eclipse e3 variant features a Miyota 9039 movement, a solid bracelet, a sunburst dial, and exceptionally bright lume. Overall, owners rate the Lum-Tec Eclipse highly for its slim design and attractive dial at its price point.

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.
