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.

Longines MASTER COLLECTION MOONPHASE

Owners widely praise the Longines Master Collection Moonphase for its beautiful, legible, and mesmerizing dial, with one owner noting it balances class and complexity. The watch offers old-world charm and a romantic moonphase complication, with the Caliber L899 movement providing a 64-hour power reserve. Some owners find the $3k price point high, suggesting better value exists elsewhere, while others acquired it for around $1700 USD. One owner notes the 40mm size is a perfect fit for a 6.75-inch wrist, though its limited water resistance makes it unsuitable for adventurous wear. On balance, the consensus is that the Longines Master Collection Moonphase is highly regarded for its classic design and attractive moonphase complication at its price point.
