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.

Phoibos Reef Master

Owners widely praise the Phoibos Reef Master for its exceptional value, highlighting its sapphire crystal, DLC coating, and extensive BGW9 lume. The watch is noted for its cool lume, with one owner finding it not bulky despite its robust build. The Shamrock Green dial and texture are highly praised, as is the comfortable bracelet with solid end links. However, the bezel action is described as rough, and the basic folding clasp is a disappointment. Accuracy is reported as excellent, with one owner seeing +-2 sec/day. Some find the 42mm size almost too big for their wrists, and the date window is considered too small. Overall, owners rate the Phoibos Reef Master highly for its impressive feature set and value at its price point.
