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.

Longines PRIMALUNA

Owners widely praise the Longines PRIMALUNA for its attractive style and understated 26.5mm size, with the automatic version favored for its smooth sweep. The redesigned 34mm model features a fluid, polished case, available in steel or bi-metal, with dial options including mother-of-pearl. The automatic movement, Caliber L899, demonstrates consistent accuracy averaging a loss of 1.3 seconds per day across six positions and 3-4 seconds per day on the wrist, performing within COSC standards. The automatic movement offers a 72-hour power reserve. On balance, owners and reviewers highly regard the Longines PRIMALUNA for its blend of classic aesthetics and contemporary design updates, particularly appreciating the automatic movement's performance and the watch's overall stylish appeal.
