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 Jazzmaster Lord Hamilton Auto Chrono

Owners widely praise the Hamilton Jazzmaster Lord Hamilton Auto Chrono for its clean, classic, and highly legible dial, with one noting its lume charges quickly and brightly. Stellar timekeeping is reported, with one owner seeing +2 or 3 seconds per day. The watch is described as bridging the gap between casual and dressy, and comfortable for its size. However, one owner found the watch felt "kind of cheap" and was "honestly not that happy with it," while another questioned Hamilton's quality control after receiving a watch with a dial blemish and a temporarily broken day/date function. Some owners express skepticism about the $650 price point, with one suggesting they would only pay $250. The stock leather band is described as nice but stiff, and the lugs are shorter than preferred by one owner. The watch features a sapphire crystal with great anti-reflective coating and a modified Valjoux 7750 movement with extra power reserve.
