Hamilton Khaki Aviation Pilot Day-Date - Air Zermatt AutovsLorier Hyperion SII

The Hamilton Khaki Aviation Pilot Day-Date - Air Zermatt Auto is widely praised for its value, with reviewers noting the Swatch Group's economies of scale contribute to its affordability. Owners and reviewers highlight the large, easy-to-read dial, with one source specifically mentioning the "ice-cold" blue degradé sub-dials as an unusual chromatic anomaly for its price point, and another noting the painted, luminous indices as a significant advantage. The 42mm case is described as offering a nice mix of brushed and polished finishes, and the slightly domed sapphire crystal enhances readability. The H-21 caliber provides a 60-hour power reserve and an anti-magnetic silicon balance spring, while the ETA 2834-2 movement offers precise day/date changes, though one source notes its 40-hour power reserve requires weekly winding. Some criticism is directed at the use of three different fonts and inconsistent color matching for the day/date indicators.

Owners widely praise the Lorier Hyperion SII for its vintage aesthetic, glossy black dial, and tasteful text. One owner notes the Miyota 9075 movement and calls it the best GMT under $800. Criticisms include a small GMT hand that is difficult to spot, and one user found the winding action not smooth with significant crown resistance. Overall, owners rate the Lorier Hyperion SII highly for its vintage aesthetic and value.
