One owner noted the quartz movement gained 8 seconds over several months.

Hamilton Khaki Aviation Air Race Auto

Owners widely praise the Hamilton Khaki Aviation Air Race Auto for its legibility and practicality, with some appreciating its countdown bezel and GMT pointer. However, opinions on its design are split, with some calling it a "Frankenstein" and disliking the skeleton hands, while others find the hands suitable for a pilot watch. One owner notes the lume is underwhelming and the 44mm size may be too large for some wrists. The original strap is also described as uncomfortable and prone to water stains. On balance, owners value the Hamilton Khaki Aviation Air Race Auto for its legibility and practical features, despite a polarizing design and some comfort concerns.
