Hamilton Jazzmaster Thinline AutovsSeiko King Seiko Chronometer

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.

Seiko King Seiko Chronometer 5626-7170 owners praise its rare grey and "Superior Chronometer" dials for their depth and sunburst finishing, which are best appreciated in person. The 36mm case is noted to wear slightly larger due to its lugs. The 5626 movement is recognized as a higher-grade chronometer-adjusted caliber than the 5606, keeping accurate time. A known issue with the 5626 movement is the quick-set date function's susceptibility to failure due to a plastic part, with no replacement part developments reported. On balance, owners value the Seiko King Seiko Chronometer 5626-7170 for its distinctive dial finishing and chronometer-grade movement, despite the potential date function issue.
