What people say

Owners + reviewers, side by side

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

Citizen Series 8 870

The Citizen Series 8 870 is praised for its sharp 40mm steel case with unique bezel construction and a glossy dial featuring finely brushed and polished applied hour markers. It is powered by the in-house caliber 0950 automatic movement, which operates at 4Hz and offers a 50-hour power reserve with enhanced magnetic resistance. The limited edition features a black Duratect DLC coated case, a carbon fiber dial, and is regulated to -5/+10 seconds per day. On balance, reviewers highlight the Series 8 870's distinctive case finishing and the robust in-house movement as key strengths.

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.
