Sinn 910 SRS

The Sinn 910 SRS is praised for its handsome, balanced dial design, featuring a cream dial with red accents and a three-register display. Reviewers highlight its flyback column-wheel chronograph complication as fitting for Sinn's innovative tool watch ethos, powered by a modified ETA 7750 movement. The watch's build is noted for being anti-magnetic, shock-resistant, and water-resistant. On balance, reviewers rate the Sinn 910 SRS highly for its classic yet distinct design and its pragmatic, well-executed chronograph functionality.

Fortis Marinemaster M-44

The Fortis Marinemaster M-44 is praised for its excellent build quality and wearability, featuring a highly legible dial and a COSC-certified Kenissi-based movement that ran at 0 seconds per day. Owners appreciate its 70-hour power reserve and the inclusion of multiple straps and a deployant buckle, noting its gorgeous appearance and great wrist presence. A minor point raised is the 21mm lug width, with a wish for it to be 22mm. The Fortis Marinemaster M-44 is priced at $4,150. Overall, owners and reviewers rate the Fortis Marinemaster M-44 highly for its robust specifications and comfortable wearability at its price point.
