The domed watch crystal - also known as box glass - allows the watch to be visible from any angle. In contrast to its historical predecessors, in this timepiece it is made of modern sapphire crystal, which provides the refined watch face with state-of-the-art scratch-resistant protection.
A sign of the times
The historic Certina logo with the double C, which also features on the crown, adorns the back of this watch, subtly emphasising its vintage look.
A sign of quality in classic timepieces: The gently curved hands that match the curve of the dial. Seen from above, this fine detail is almost invisible. But it has a vital task - it ensures that the hands perform their task, gliding over the curved dial incredibly evenly and accurately.
A dial with a difference
The domed dial is one of the hallmarks of a classic wristwatch. The curved design was once intended to enclose the large movements used in decades gone by - now, it is a sign of traditional watchmaking. After all, the extremely thin sections must be handled with absolute care. This is the only way to ensure that they provide a flawless canvas on which the displays can rest.
This scale can be used to calculate distances using the speed of sound. For instance, it can be used to determine how far away a storm is. All the wearer needs to do is activate the second hand when they see the lightning and stop it again once they hear thunder. Originally, it was primarily military watches that featured this functional display.
