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 8 890

The Citizen Series 8 890 is praised for its robust build, 200 meters of water resistance without a screw-down crown, and excellent case finishing for its price. Reviewers note the smooth action of its internal bezel, though one suggests the knurling could be more pronounced for better grip. It utilizes the caliber 9051 automatic movement with a 42-hour power reserve, which often performs better than Citizen's stated -10/+20 seconds per day. The watch's design is noted as borrowing from popular luxury sports watches, and its lug-to-lug measurement can make it wear large. Overall, reviewers find the Citizen Series 8 890 a compelling and robust sports watch, particularly for its finishing and water resistance capabilities.

From video reviewers

Advanced finishing techniques on the 42.6mm octagonal silver-tone stainless steel case showcase durability and elegance. The watch's textured blue dial may not appeal to everyone's taste. Reviewers disagree on whether the Citizen Series 8 890's movement (Caliber 9051) is a strong point due to differing comparisons (Grand Seiko vs. AP Royal Oak).

Formex Reef 42 mm

The Formex Reef 42 mm is widely praised for its comfortable bracelet featuring a micro-adjust clasp, COSC-certified Sellita movement, and excellent build quality. Owners appreciate the gradient dial's visual appeal and the overall wearability. Some owners note the seconds hand does not perfectly align with markers, and one owner found the lugs' taper hinders third-party strap fit. The bracelet's length and sporty design are noted as limiting versatility by some. On balance, owners and reviewers rate the Formex Reef 42 mm highly for its impressive wearability and value at the price point.
