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 Field King Day-Date

Hamilton Khaki Field King Day-Date owners widely praise its classic styling, 80-hour power reserve, and excellent value. Opinions on water resistance are split; some express concern over the 50m rating, while others find it sufficient for daily wear and swimming. One owner notes the stock strap can be stiff. Service costs range from $55 for routine maintenance to $220 for full service with movement replacement. On balance, owners rate the Hamilton Khaki Field King Day-Date highly for its classic aesthetics and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-40 automatic movement is a significant strength. The 50-meter water resistance is considered a limitation for a field watch.

Marathon Steel Navigator SSNAV-D Auto

The Marathon Steel Navigator SSNAV-D Auto is praised for its durable construction, featuring a sandblasted steel case with improved lugs, a bi-directional bezel with excellent action, and 100m water resistance. Owners appreciate the constant visibility provided by self-illuminating tritium gas tubes and the precision of its ETA F06.412 quartz movement, which offers accuracy to about 10 seconds per year. The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.
