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.

However, opinions are divided on the strap quality, with one owner finding it soft and satisfying, while another calls it poor. Some owners express concerns about the brand's overall quality and durability, with one noting a friend's misaligned hands and another finding the design unappealing. On balance, owners are split on the Knot Watches CS-38ASV, with appreciation for its unique dials and wearability tempered by concerns over build quality and strap execution.
