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.

Grand Seiko SBGY002

Owners and reviewers widely praise the Grand Seiko SBGY002 for its impeccable design, finishing, and attention to detail, highlighting its slender 38.5mm case and thin profile for comfortable wear. The Spring Drive movement, calibre 9R31, is noted for its accuracy within one second per day and a 72-hour power reserve, with one owner appreciating the movement's finishing and the watch's overall class and simplicity, preferring the power reserve indicator on the case back. The Snowflake dial's appearance changes with light, often appearing less yellow than expected, and a matte blue strap can make the SBGY002 more casual for daily wear, complementing the seconds hand. The Grand Seiko SBGY002 is considered a home run for its combination of iconic dial and dress case, though its yellow gold construction and price point position it differently than steel alternatives.
