Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Tsuyosa 37mm

The Citizen Tsuyosa is praised for its gorgeous dials and nice finishing, with owners finding its white dial versatile and its overall wrist presence excellent. Some owners note a rattling integrated bracelet and a small, awkwardly positioned crown. The Miyota 8210 movement is described as noisy but keeps good time, though its 40-hour power reserve requires resetting after weekends. The lume is considered pitiful, and the date magnifier disappointing. On balance, the Citizen Tsuyosa is a fun, people-pleasing watch, with its primary draw being its attractive dial and finishing at a competitive price point.

From video reviewers

The Citizen Tsuyosa's compact size and versatility are notable strengths, with the 37mm case being a welcome addition to the series. The watch's price point under SGD 600 is also a positive aspect. A weakness is the integrated bracelet's potential for rattle.

Decima Gatekeeper

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.
