Hamilton Jazzmaster Thinline AutovsSternglas Naos Pro Automatik

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.

The Sternglas Naos Pro Automatik is praised for its slim, wearable 38mm case with a mix of brushed and polished finishes and a refined Bauhaus dial design. Reviewers note the upgraded Miyota 9015 movement and improved wearability. Some find the optional five-link bracelet too chunky and lacking refinement, with one reviewer noting its accuracy of -10/+30 seconds per day is not for precision enthusiasts. On balance, reviewers rate the Sternglas Naos Pro Automatik highly for its slim case and refined dial design at its price point.
