What people say

Owners + reviewers, side by side

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

Maen Grand Tonneau Ultra Thin

Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.

Seiko DressKX

The Seiko 5 Sports SKX series is widely praised as a gateway mechanical watch offering exceptional value and iconic status, with owners appreciating its ruggedness, tool-like authenticity, and moddability. Many owners report the 4R36/NH36 movement achieves accuracy of +/-5 to 10 seconds per day, far exceeding its stated specifications, and the stock Jubilee bracelet is noted as surprisingly comfortable. Some owners find the Seiko 5 Sports SKX series bulky and less aesthetically pleasing than newer models, with others noting its specifications lag behind contemporary watches. The Seiko 5 Sports SKX series is considered a decent watch, especially when found under £200, but it's not the serious tool watch the original SKX was, lacking a screw-down crown, bezel pip, and ISO rating. Overall, owners rate the Seiko 5 Sports SKX series highly for its iconic dive watch lineage and excellent value at the price point.

From video reviewers

The clean dial and versatile dressy look are praised. The overall thickness and handset are points of contention.
