What people say

Owners + reviewers, side by side

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

Maen Grand Tonneau Ultra Thin

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.

Tudor Black Bay 58 925

The Tudor Black Bay 58 925 is praised for its unique taupe dial and bezel, and COSC-certified movement. Owners widely report the silver case scratches and dings more easily than steel, and some experience tarnishing despite anti-tarnishing claims, though it can be cleaned with an eraser or silver cloth. While some find the leather strap uncomfortable due to weight imbalance, others consider it suitable. The dial can appear washed out in certain lighting, and one owner notes the long springbar can scratch the case if it pops out. On balance, owners and reviewers appreciate the Tudor Black Bay 58 925 for its unique silver case and taupe dial, despite concerns about scratching and tarnishing.
