What people say

Owners + reviewers, side by side

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

Massena LAB Dato-Racer

Owners widely praise the Massena LAB Dato-Racer as an excellent everyday watch, appreciating its blend of 1970s-inspired aesthetics with modern dimensions. This model is a limited edition of 99 pieces. On balance, owners rate the Massena LAB Dato-Racer highly for its successful fusion of vintage design and contemporary wearability.

Hamilton Khaki Field King Auto

Owners and reviewers widely praise the Hamilton Khaki Field King Auto for its 80-hour power reserve, hacking capability, and snappy day-date function, with accuracy figures ranging from +1 to +5 seconds per day. The watch is also noted for its legibility, attractive dial options, and 100m water resistance. Some owners find the stock strap stiff and the case finishing lacks fine detail, while others mention the lume is decent but fades significantly after about 30 minutes. The lack of an anti-reflective coating on the sapphire crystal is a recurring point, and the crown does not feel like it fully pushes in for some. On balance, owners and reviewers rate the Hamilton Khaki Field King Auto highly for its robust feature set and value, particularly its day-date complication and extended power reserve.

From video reviewers

The 80-hour power reserve from the H-40 movement is a significant advantage. The lack of AR coating on the sapphire crystal hinders legibility in direct light, and the 50-meter water resistance is limited for a field watch. Reviewers disagreed on the watch case geometry and ergonomics, with one noting it contributed to buyer's remorse and another suggesting it should offer a comfortable fit.
