What people say

Owners + reviewers, side by side

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

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.

Tudor Pelagos Ultra

The Tudor Pelagos Ultra is praised for its 1000 meters of water resistance, METAS-certified Calibre MT5612-U movement, and fully lumed dial and bezel. Reviewers highlight its titanium case and self-adjusting clasp as key features. The Tudor Pelagos Ultra is slightly larger at 43mm than some other models in the line but wears comfortably. Overall, owners and reviewers rate the Tudor Pelagos Ultra highly for its technical specifications and comfortable wearability as a flagship dive watch.

From video reviewers

The Tudor Pelagos Ultra's all-titanium construction provides a lightweight and durable case. One weakness is the lack of lume brightness. Reviewers disagree on whether the helium release valve is a notable feature or a drawback for a more streamlined design.
