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.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
