Reviews

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

Hamilton Jazzmaster Thinline Auto

The Hamilton Jazzmaster Thinline Auto is widely praised for its gorgeous, stunning, and captivating dials, particularly the champagne and burgundy variants, and its thin, comfortable, vintage-inspired design that fits well under shirt cuffs. Owners appreciate its clean, simple aesthetic, often noting the beauty of its applied indices and dauphine hands, and the slim profile afforded by its movement. Some users find the absence of a second hand liberating for quick setting and avoiding accuracy checks. However, opinions are mixed on its thinness, with some finding it too thin for their preference. The ETA 2892-A2 movement's rotor noise is noted by several owners as audible due to the thin case, and the winding feel is described by one owner as unrefined. The small crown is also flagged as difficult to manipulate, and the OEM strap is disliked by one owner. One source mentions the polished case may show light swirlies.

From video reviewers

The slim case profile and affordable price point are consistently praised. Reviewers noted the absence of a second hand.

Kurono Tokyo Anniversary 2021 Toki

Owners widely praise the Kurono Tokyo Anniversary 2021 Toki for its stunning, dynamic coral-vermillion dial that shifts hues, and its classic 37mm polished case, making it a versatile summer watch. The radial sunburst dial, inspired by the Japanese crested ibis, displays metallic shades from crimson to vermillion red, with hints of purple under certain lighting. Reviewers and owners alike admire the brand's design identity and thoughtful limited production. One owner notes the Miyota 90S5 movement is performing exceptionally well, running at +2/3 seconds per day, exceeding previous experiences with the model line. Some owners find the watch stunning with classic sizing and a dynamic dial that changes in the light, with one owner considering it the brand's most beautiful non-chronograph watch. The three polished rings inside the minute track are also highlighted as stunning and original.
