Product Details

Blue is clearly a trend today in the watch industry - blue dials, blue hands (and we've even seen blue cases).

But Fortis gets blue right on this watch with extreme contrast and legibility.

We've seen a number of marine watches over the years, and there is one design element of the Fortis Aquatis Marinemaster that we noticed immediately - the bezel. This bezel features a unidirectional ratcheting mechanism and a count up color coded insert for tracking elapsed time.

Unlike most marine watches, the bezel on the Fortis Aquatis Marinemaster features large knurled lunettes which offer an easy to grip surface - even when wearing gloves.

This watch features a matte black dial with large Arabic numerals complete with a vivid blue color scheme to match the color coded bezel.

This color scheme is further reflected in the hands which feature white sword style hour and minute hands and a second hand complete with luminous pip and blue accents for increased legibility.



As an added benefit, this watch also features a day/date display at the 3 position with the day display in either English or German (you change the settings through the crown).  The day of the week and date are set against a white background for added contrast with the matte black dial.

Notice the two white triangles on either side of the day/date display.  These triangles are not decorative – they actually indicate how to set the day and date.  Using the second crown position, turn the crown clockwise to set the date and counter-clockwise to set the day.

The Fortis Aquatis Marinemaster features a satin finished case and screwed case back. The large crown is designed for ease of use and is finished with an engraved Fortis logo.

The final touch can be seen on the case back itself which features a traditional submarine motif which can be found throughout the Marinemaster collection.


Important features of this watch include:

  • Large knurled bezel design
  • Color coded bezel for legibility
  • Double anti-reflective coating
  • Water resistant to 200 meters


This watch is fitted with a black silicone rubber strap and a diver style deployant with micro adjustments.
