Hamilton Khaki Aviation Pilot Day-Date - Air Zermatt AutovsVario 1918 Medic Brass

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 Vario 1918 Medic Brass for its crisp enamel dial, easy-to-read numerals, and cathedral hands, noting the brass case develops an attractive patina over time. However, the soft brass scratches easily, and one owner found the lume to be poor. Accuracy varies, with one example running slow by about 10 seconds per day and another owner deeming the Miyota 82s5 movement just okay. On balance, owners rate the Vario 1918 Medic Brass highly for its unique dial and the evolving character of its brass case.
