Sinn 717vsMaen Grand Tonneau Ultra Thin

The Sinn 717 is widely praised for its legible, cockpit-instrument-inspired dial and the functional SZ01 movement with central chronograph minute and second hands. Owners appreciate its solid winding action, crisp button feel, and accurate date changes. Despite its 45mm diameter, the Sinn 717 wears well due to its short lug-to-lug distance and comfortable strap options, and its TEGIMENT-treated black PVD case offers significant scratch resistance. Reviewers highlight its robust build quality and 200m water resistance, noting the innovative bezel sealing. Some community members criticize the blacked-out case aesthetic, and one owner finds the bezel action stiff, which they also see as a positive for preventing accidental turns. On balance, owners and reviewers rate the Sinn 717 highly for its unique legibility, robust construction, and comfortable wearability at its price point.

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.
