Fortis Watch Aquatis Shoreliner Champagne Beach 655.18.38 LP.10. As Fortis is known for its rugged diving watches like the Marinemaster or Diver, the evolution continues, from the depths of the seas to the beaches of our planet without neglecting the 20 atm water resistance. The design is made for all beach lovers and those who enjoy clear visibility of the time spent in the sun. Due to the absence of numbers and the clear, simple structure, the Shoreliner models are setting up a new chapter in the Aquatis world.
