What people say

Owners + reviewers, side by side

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

Marathon OSAR-D (Original SAR with Date) Automatic 41mm

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

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.
