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 LX line

Owners widely report the dial's blue-green sunburst is phenomenal, and the sapphire glass features blue AR coating. Some owners feel the high price limits discounts and sales, with one AD noting extremely low sales due to the cost. One owner reported DLC peeling off a two-week-old watch, and another noted quality control issues like bezel inserts and fallen second hands. On balance, owners consider the Seiko Prospex LX line a nicely built watch, though pricing led to poor sales and its discontinuation.
