Editor's Notes

Watchmaking pioneer Fortis describes the 'Marinemaster M-40' as "a true outdoor companion". Sporty yet refined, this reference has a robust recycled stainless steel case and bidirectional Gear Bezel™ in blackened steel. It's powered by a UW-30 Performance movement with an antimagnetic, gilt Glucydur balance wheel for improved precision. The 'Rockstone' grey tone is mirrored through the patterned dial and 'Horizon' rubber strap.
