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).

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
