Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
