What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Gruppo Gamma Field III GMT Date

Owners widely praise the Gruppo Gamma Field III GMT Date for its awesome looks, quality, and good value. The watch features a 40mm brushed 316L stainless steel case, box sapphire crystal, and 200m water resistance, powered by a Seiko NH34A movement. Some reviewers note the NH34A movement's accuracy can range from -20~+40 seconds per day, though one reviewer reported +5 seconds per day with a regulated movement. The dial's dense layout with Arabic numerals can be overwhelming for some, and one owner found the size unsuitable for smaller wrists. On balance, owners rate the Gruppo Gamma Field III GMT Date highly for its impressive finishing and toolish design at its price point.
