Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Decima Gatekeeper is praised for its hypnotizing dial, with design elements that draw comparisons to the Ingenieur and Czapek. Owners note the watch features a Miyota 9039 automatic movement, a 38mm case, and 50m water resistance. On balance, owners rate the Decima Gatekeeper highly for its striking dial design.
The Dumoreau DM02 is widely praised for its cohesive and intricate dial design, with specific mentions of its striking salmon and blue colorways, and eye-riveting concentric dial elements. Owners and reviewers alike appreciate its elegant 39mm case size and comfortable, ergonomic design with sloping lugs. The manual-wind Sellita SW210-1 movement is noted for its surprising thinness, good finishing, and a winding action described as a joy, with accuracy reported around +/-7 seconds per day. The watch is considered beautiful for its price point, with some finding it offers a sporty yet modern feel. Some owners find the Dumoreau DM02 can be too dressy for casual wear and too casual for the dressiest occasions, and one user expressed concern about scratching the polished case. The 100m water resistance is noted, though the included Italian leather strap is not considered ideal for swimming. The watch is offered for $975.
