What people say

Owners + reviewers, side by side

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

Citizen Tsuyosa Automatic

The Citizen Tsuyosa Automatic is widely praised for its exceptional value, with reviewers and owners alike highlighting its Japanese construction quality and impressive fit and finish for the price. Enthusiasts appreciate its versatile design and fun dial colors, while reviewers note its retro feel and emulation of vintage dress watches. The watch is powered by Citizen's caliber 8322 movement, offering a 60-hour power reserve. Criticisms include a cyclops date magnifier that some find undesirable, a bracelet that can be noisy and lacks significant tapering, and a 40mm case that wears large due to its thickness and broad lugs. One owner also found the 4 o'clock crown fiddly for winding. Overall, owners and reviewers rate the Citizen Tsuyosa Automatic highly for its incredible bargain price and well-executed design.

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.
