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.

Fears Onyx (collective Horology)

Owners widely praise the Fears Onyx (collective Horology) for its exquisite glossy black onyx dial, which displays microscopic striations under magnification. Reviewers note its thin case, under 10.5mm, and a balanced sporty-dressy aesthetic. Water resistance is rated at 150m by one source and 100m by another, and the bracelet features on-the-fly micro-adjustment. Some owners find the 39.5mm diameter slightly large for the style, and one source suggests it doesn't represent top value, though it remains competitive. Overall, owners rate the Fears Onyx highly for its unique stone dial and wearability.
