Using BGW9 Swiss Super-LumiNova, this watch glows in a striking cool blue hue across the hands, hour plots, and bezel pip.
Its brightness and longevity make it a reliable companion for nighttime dives or dark environments.
Each watch features the Heimdallr shark engraving on the titanium caseback — a nod to strength, precision, and marine exploration.
The offset crown at 4 o’clock improves comfort and reinforces the tool-watch authenticity.
