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.

Longines HYDROCONQUEST GMT

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
