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 compelling value proposition and modern Japanese design with a sporty edge. Reviewers note its 40mm steel case, glossy dial with applied markers, and the in-house Calibre 0950 automatic movement offering 50 hours of power reserve and enhanced magnetic resistance. The flat sapphire crystal is noted to collect fingerprints, and the solid caseback omits a view of the movement. The limited edition variant features a 40.8mm black DLC-coated case, a carbon fiber dial, and the 0950 movement regulated to -5/+10 seconds per day. Overall, the Citizen Series 8 870 is viewed as a strong offering for its blend of design and features.

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.
