"Diving takes you into previously undiscovered spheres and into some of the last unchartered waters of the earth. Whether as a hobby or calling, it is a sport that demands resilience, good condition, strong nerves and a love of adventure on the part of the diver. One of the basic requirements of diving is to minimise the risks as much as possible, which is why good equipment is essential. This is where a watch that can resist extremes of water pressure and on which you can count in any situation comes into play: properties that are united in the Ternos series. It has a sturdy, satined, stainless steel case with unidirectional rotatable bezel for monitoring diving times. The back, crown and pushers are screw-out. An extra thick, sapphire crystal front is made to resist an atmospheric pressure of up to 20 ATM. The Super-LumiNova luminous elements on the figures and markings simplify reading the time in the dark. However, it is worth remembering that Super-LumiNova is an inactive substance, so can only emit light once it has absorbed it. The metal strap of both the chronograph and the automatic version has a snap buckle with a safety clip and integrated extension, which enables the diver to wear the watch over his diving suit. These quality characteristics are impressive and so it is hardly surprising that the Ternos Diver has been a very popular model in the DAVOSA collection for years.
