Reviews

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

Hamilton Khaki Aviation X-Wind Day Date Auto

Owners widely praise the Hamilton Khaki Aviation X-Wind Day Date Auto for its value and technical, busy aesthetic, with many appreciating its versatility with straps. Reviewers highlight its handsome, easy-to-read dial with raised indicators and a brushed silver finish, and some owners find the 42mm size excellent. However, the watch's crosswind calculation features are deemed useless by some, and its lume is criticized as weak or practically non-existent. Owners are split on the updated design, and some find the left-handed crown and pusher setup uncomfortable, while others note the large size may not suit all wrists. Overall, owners and reviewers rate the Hamilton Khaki Aviation X-Wind Day Date Auto highly for its perceived value and bold, complicated aesthetic.

From video reviewers

The H-21 movement's 60-hour power reserve is a notable strength. The large 44mm case size was mentioned as a potential drawback.

LIV Watches P-51

Owners widely praise the LIV Watches P-51 for its excellent build quality, attention to detail, and striking pilot design, with many noting that images fail to capture its full appeal. Reviewers highlight its legibility, aided by BGW9 lume and an anti-reflective crystal, and its robust construction, including titanium and matte ceramic options. One owner notes the Valjoux 7750 movement is regulated to within +/- 4 seconds per day. However, one owner expresses concern about lume performance, referencing past discussions about LIV watches, and prices range from $550 to $1931 AUD depending on the specific model and variant. Overall, owners and reviewers rate the LIV Watches P-51 highly for its distinctive design and solid construction at its price point.
