Swiss watch brand DELMA presents Quattro, a limited edition decompression divers’ watch with a water resistance of 500 meters.
Dedicated to professional divers, this robust tool watch has a unique symmetrical stainless-steel case which subtly integrates the helium escape valve and protects the hidden screw down crown from potential impact.
The unidirectional diving bezel in stainless-steel or black DLC is empowered with six bold notches for easy grip while enhancing the Quattro’s distinctive symmetry.
This timepiece comes with DELMA’s specialized Rapid Bracelet Exchange System (RBES) that enables the case to perform in 3 distinct forms. The bracelet and rubber strap can be quickly interchanged without the need for any tools. Likewise, the watch can be effortlessly fixed onto a custom designed decompression plate in a matter of seconds.
To release the watch, one simply pulls up the lever and turns the case clockwise by one hour, moving the lever from 8 to 9 o’clock. To attach it, the lever is positioned at 9 o’clock and the watch is turned counterclockwise while pressing it down gently until it clicks in. The DELMA RBES is based on the bayonet mount mechanism which is easy and safe to operate in all conditions.
The crown possesses a special notch so it can be simply unscrewed with its bespoke tool, a coin or by hand by removing the watch head.
The aluminum decompression plate allows the watch to be directly connected with the essential data based on the research of Swiss dive pioneers Hannes Keller and Albert Bühlmann.
The plate outlines two sets of data– one for diving in the mountains 700masl and higher and one below 700masl.The decompression plate can safely be attached to oxygen tanks or other gear through its spring snap hook.
The minute and lollipop seconds hands are emphasized with orange while the hour hand is defined in white. The hands, matching round hour markers on the dial and quarter-hour markers on the bezel, are all treated with Super Luminova C5.
The original DELMA Quattro watch was launched in the early 80’s with a quartz movement. Limited to 999 pieces, the new edition is powered by an automatic SW200-1 movement.
The Quattro is available with a black, blue or orange dial and with a stainless-steel or black DLC bezel ring. The brushed stainless-steel bracelet is equipped with a deployant clasp with pushers while the rubber strap features a stainless-steel buckle.
The DELMA Quattro watch is accompanied by a blue leather travel case and a special box to store the watch, strap, and the decompression plate.
