Reviews

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

Bremont Supernova

The Bremont Supernova is praised for its well-balanced proportions and comfortable wear, with a premium feel that aligns with its price point. Owners appreciate the white dial's depth and the integrated bracelet design. However, some find the design derivative and the £8,000 price tag optimistic, with criticisms of the double-digit date window and crown guard design. One owner notes the chronograph seconds hand's gold tone does not complement other elements. Overall, owners and reviewers rate the Bremont Supernova highly for its comfortable wear and premium feel at its price point, despite some design criticisms.

Certina DS-1 Chrono Auto

Owners widely praise the Certina DS-1 Chrono Auto for its elegant design, value, and 100m water resistance. Reviewers highlight its handsome, sober tool-like demeanor and good build quality from Swatch Group. One owner notes the watch is a dressier option than a dive watch, appreciating its Super-LumiNova and AR sapphire crystal. The 42mm case is described as not feeling too large due to a relatively thin profile. Some owners report the included leather strap can be uncomfortable and the clasp sharp. One reviewer noted the date window on a similar model appeared disproportionate and the crystal attracted glare due to a lack of AR coating, though other sources mention AR sapphire crystal. Accuracy figures vary, with one owner seeing +4s/day and another noting the Valjoux A05.231 movement. Overall, owners and reviewers rate the Certina DS-1 Chrono Auto highly for its handsome design and strong value proposition.
