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

Seiko Prospex Sea models are widely praised for their excellent build quality, value for money, and comfortable wearability, with many appreciating the vintage-inspired designs and robust construction. Owners note the silicone straps are surprisingly comfortable and well-finished, and the Lumibrite lume is excellent. However, some find the 44.3mm size and thickness too large for smaller wrists, though others report the sizing as perfect. The 6R15 movement in some variants offers accuracy around +4 seconds per day with a 50-hour power reserve, while newer movements offer more. Some models are criticized for a bracelet width not matching the case size or a rudimentary clasp for their price point. Overall, owners and reviewers rate the Seiko Prospex Sea highly for its impressive case work and finishing at its price point.
