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.

Jack Mason Ellum Manual Wind

The Jack Mason Ellum Manual Wind is widely praised for its elegant, contemporary dress watch design, featuring a unique linen-textured dial and slim 38mm case. Owners and reviewers consistently highlight the dial's beauty and the watch's refined aesthetic, with some noting its mid-century inspiration. The Sellita SW210-1 manual-wind movement is regulated to ±5 seconds per day, and the watch is available for $799 to $949. Some owners find the date window detracts from the dial's design, and one reviewer notes the red, white, and blue seconds hand as a potentially distracting accent. On balance, owners and reviewers rate the Jack Mason Ellum Manual Wind highly for its beautiful dial and slim case at the price.
