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.

Longines LA GRANDE CLASSIQUE DE LONGINES

Owners widely praise the La Grande Classique de Longines for its extreme thinness, elegance, and timeless simplicity, with many finding it comfortable and lightweight due to its slim, flat design. The quartz version is recommended for its accuracy and convenience, while both quartz and automatic models are noted for their slim profiles and elegant aesthetics, with the bracelet being comfortable. Some owners are split on the styling, with Roman numerals appealing to some but not all, and one owner finds the Tonneau collection model a lovely dress watch despite preferring round faces. Owners suggest pre-owned options for better value, with prices ranging from $300-$1000 USD depending on the model and condition. One owner reports frequent battery replacements on the quartz model, with batteries lasting only months. Overall, owners rate the La Grande Classique de Longines highly for its slim, elegant design and value, particularly on the pre-owned market.
