Oris Carlos Coste Limited Edition IV

This is a diver’s watch that is within reach to most of us with a PADI approved license. Traditional Swiss watch brand Oris introduces the new Carlos Coste Limited Edition IV, a highly functional diver’s timepiece made with free diving in mind. This extreme sport requires the diver to hold their breath for several minutes.

This is what drives Oris’s long-time brand ambassador and record-breaking free diver Carlos Coste. In 2003 he became the first person to break the 100-metre barrier in the free immersion category, and in 2010 he set a new Guinness World Record by swimming 150 metres through Dos Ojos, a vast underwater cave network in the Yucatán Peninsula, Mexico, on a single breath. Impressively, he can hold his breath for seven and a half minutes, earning him the nickname ‘El Acuaman Criollo’ (which roughly translates as ‘the natural waterman’) in his native Venezuela.

There’s no one better qualified to test watches underwater, which is why Oris has worked closely with Carlos since 2006. Ahead of his latest record-breaking attempt in 2015, the independent Swiss company is introducing the new Carlos Coste Limited Edition IV.

The watch’s diving credentials start with a multi-piece 46mm case made from robust yet lightweight titanium. In the murky depths underwater, legibility is hugely important, which is why Oris has equipped the unidirectional rotating top ring with a white Super-LumiNova® minute scale set into the black ceramic inlay to allow the wearer to read the dive time remaining at a glance.

Its black dial has applied indices and hands filled with bright orange Super-LumiNova®, while the sapphire crystal is domed on both sides with anti-reflective coating to minimise glare. The watch is water-resistant to depths of up to 50 bar (500 metres).

Another smart touch is the dark orange dot on the manual helium valve at 3 o’clock, designed to help divers quickly distinguish the valve from the time and date setting crown at 2 o’clock. Inside the watch ticks an automatic movement, which powers a date at 3 o’clock and a small seconds sub-dial between 7 and 9 o’clock.

The watch comes on a black rubber strap – with the option of a titanium bracelet – which features Oris’s ingenious quick adjustment sliding-sledge folding clasp system.

Oris has engraved the case back of the Carlos Coste Limited Edition IV with Carlos’s unique emblem, and the watch is limited to 2,000 pieces.
