What people say

Owners + reviewers, side by side

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

Bremont Supernova

The Bremont Supernova is praised for its new ENG375 movement, big date, and power reserve indicator, with its 40mm steel case featuring mixed finishing and an integrated bracelet. Owners note good but not great lume, well-balanced proportions, and a premium feel for its price, despite a 173-gram weight. Some community members find the design derivative and the £8,000 price tag overly optimistic, with mixed views on the date window and crown guard. The proprietary Trip-Tick case construction offers shock protection, and the movement provides a 65-hour power reserve. Overall, owners and reviewers highlight the integrated bracelet and proprietary movement as key strengths of the Bremont Supernova.

Hamilton Khaki Aviation X-Wind Auto chrono

Owners widely praise the Hamilton Khaki Aviation X-Wind Auto chrono for its good quality for the price and versatility with straps. Reviewers highlight its unique drift angle calculator function as a horological curio and legitimate navigational tool, noting its modified Valjoux 7750 movement provides a 60-hour power reserve. Some owners find the busy dial and left-handed crown/pusher setup unusual, and its lume could be stronger, while others consider it a heavy travel watch with features not useful for everyday use. On balance, owners and reviewers rate the Hamilton Khaki Aviation X-Wind Auto chrono highly for its functionality and build quality at its price point.
