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.

Seiko Prospex Sea

Owners widely praise the Seiko Prospex Sea for its excellent lume, robust build, and value, with many highlighting the comfortable 4 o'clock crown and reliable movements. Reviewers note impressive case finishing and attractive dials, with specific models lauded for their gradient blue designs and smooth bezel actions. Accuracy figures vary, with one owner reporting +9 seconds/day after demagnetization, while others find the watches to be good first "proper" watches. Some owners find the stock rubber straps uncomfortable or the overall size substantial on smaller wrists. On balance, owners and reviewers rate the Seiko Prospex Sea highly for its combination of strong dive watch functionality and appealing design at its price point.
