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.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
