What people say

Owners + reviewers, side by side

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

Phoibos Leviathan

Owners widely praise the Phoibos Leviathan for its excellent value, superb case finishing, and generous lume. The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.

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.
