What people say

Owners + reviewers, side by side

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

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.

Grand Seiko SBGJ237

Grand Seiko SBGJ237 owners and reviewers praise its impeccable finishing, Hi-Beat 36,000vph movement, and functional GMT complication. The watch is noted for its good value at €7,000, featuring a stainless steel bracelet with alternating brushed and polished surfaces, and a sapphire bezel with a day/night indicator. Reviewers highlight the lovely lume and the bezel's vintage-inspired, asymmetric color split, which uses LumiBrite for low-light legibility. The 9S86 Hi-Beat movement offers impressive accuracy of -5 to +3 seconds per day and a 55-hour power reserve. The SBGJ237 boasts 200-meter water resistance. However, the 44.2mm case size, measuring 14.4mm thick, may require slightly larger wrists, and its elevated crystal and less prominent bezel contribute to a thickness that might feel less substantial in person. Overall, owners and reviewers highly regard the Grand Seiko SBGJ237 for its combination of finishing, movement technology, and GMT functionality at its price point.
