Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Aquastar Deepstar Chronograph for its excellent finishing, historical appeal as a faithful 1960s tool watch recreation, and its smooth column wheel chronograph action, with some noting it surpasses competitors. Reviewers and owners alike highlight the 39mm case size as a significant improvement in wearability, though its 14.8mm to 17mm thickness is noted as substantial. The watch features a sapphire crystal with triple AR coating for excellent legibility and 200m water resistance. Some owners express a preference for a bracelet option over the included tropic and leather straps, and one reviewer found the 21mm lug width awkward. Overall, owners and reviewers rate the Aquastar Deepstar Chronograph highly for its authentic vintage tool watch character and impressive build quality at its price point.
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.
