Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely report the Maen Grand Tonneau Ultra Thin features a La Joux-Perret D101 manual-wind movement and a double-layer enamel dial. Some owners criticize the bracelet design and find the dial too small and lacking indices. One owner describes the Maen Grand Tonneau Ultra Thin as "hideous with a good movement." On balance, owners are divided on the Maen Grand Tonneau Ultra Thin, with some appreciating its movement and dial while others find its design unappealing.
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.
