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.

Lorier Hyperion SII

Owners widely praise the Lorier Hyperion SII for its vintage aesthetic, with specific mentions of the glossy black dial and tasteful text. The finishing on the case is also highlighted as excellent, and the bracelet is found to be comfortable. One owner notes the Miyota 9075 movement as a standout feature for a GMT watch under $800. However, drawbacks include the Hesalite crystal, which can warp the view at the dial's edge and scratches easily, and the GMT hand is described as small and difficult to spot. One user also reported the winding action as not smooth with significant crown resistance. Overall, owners and reviewers rate the Lorier Hyperion SII highly for its vintage charm and value, particularly for its GMT functionality and case finishing.

From video reviewers

The GMT functionality is a key strength. The Miyota 9075 movement's 42-hour power reserve is a drawback. Reviewers disagreed on the value proposition at the price point.
