The case of the Invicta Subaqua Noma V is a full 50 mm in diameter and constructed of over 36 individual micro-engineered components that have been assembled with high precision. The case back of this chronograph is transparent so as to allow the complex movement to be viewed. The unidirectional rotating diver bezel features five riders that allow a firm grasp under any conditions, both on land and underwater. A patented screw-crown and pusher system makes it possible to elevate the pusher without compromising the watch’s high water resistance, which has been tested to a depth of 500 metres. Further practical features include the solid stainless-steel watchband, the safety buckle and the luminous hands and markers.
