When it comes to water-resistant watches with a robust feel, Swiss watchmakers Edox are no strangers to the segment. The independent Swiss watch brand have been constantly working towards raising the bar since the inception in 1884. From the popular Delfin timepiece of 1961 with a patented crown system to the Hydro-Sub of 1965 with a water resistance of at least 300m, the brand have specialised in creating aquatic timepieces that are the ideal diver’s watches for adventurers and explorers. Over the decades, Edox have built a reputation as ‘the water champion’ of the watch world and the bold, accurate and extremely durable CO-1 series is an integral part of the Edox world.

A Brief Overview of the Edox CO-1 Collection

Launched in 2006, the CO-1 was specifically designed for performance and extreme adventure. Engineered for offshore powerboat racing, the timepiece offered a bold fusion of high water resistance with a helium-escape valve at nine o’clock, extreme sturdiness with a scratch-resistant sapphire crystal glass and ceramic bezel, with attractive aesthetics in different dial colours. The collection symbolised the brand’s commitment to Swiss watchmaking, which includes functional designs, hand-assembling techniques and technical innovation. Each CO-1 is subjected to Edox’s meticulous quality controls in real water before being released. Its reliability as the ultimate companion for timekeeping has been proven by being put to test by team Australia’s offshore pilots for several years and performing perfectly.

The Edox CO-1 Chronograph In Titanium

One of the newer CO-1 watches from Edox is the titanium chronograph. Touted as one of the world’s best Swiss-made chronographs in a certain price segment, the Edox CO-1 Titanium Chronograph is a beautiful piece of horology perfect for exploring the oceans, while even suitable for daily urban wear. 

Made from tough but lightweight titanium, the CO-1 Titanium Chronograph makes an impression with its 1,000m water resistance. The 45mm titanium case is able to withstand water pressure up to 1,000m due to the special, patented double O-ring Edox gasket that is used for the crowns and the pushers. Additionally, the presence of a 4mm-thick scratch-resistant sapphire crystal glass aids in protection and durability.
