Case and bracelet is made of fiberglass*. Aggressive-sporty design was developed taking into account the technological features of the material and the requirements for wear resistance from people of marine professions, athletes - yachtsmen leading an active lifestyle.

A large 48 mm fiberglass case with a tachymeter** scale on the bezel holds a fiberglass bracelet with a locking buckle. Durable mineral glass and a screw-locked transfer head hold water pressure of 20 atmospheres.

* Fiberglass is glass-filled material (70% fiberglass) based on polyester resins, has the strength and durability of metal, the biological stability of the polymer (does not rot, does not change color, does not become brittle). At very low temperatures (-40°C), fiberglass does not harden or shrink. This avoids the phenomenon of cracking of the material. However, at high temperatures (100°C) it retains its overall shape and stability, does not expand (no deformation!).

** A tachymeter is a device that measures the speed of a car. Knowing how many seconds it takes a car to travel 1 km, you can determine the approximate average speed per hour during the journey.

If the chronograph is started at some time and stopped after 1 km, the average hourly speed can be measured by the position of the second hand.
