It was three years after the inaugural America’s Cup reenactment race (celebrating the 1851 America’s Cup regatta, which today is the oldest international sailing competition) in 1957, that Corum released its first Admiral watch. The brand worked with the race organization, for which it was a sponsor, to establish the first then-square Admiral watches that made their debut in 1960.

Two decades later, in 1980, the Corum Admiral collection was totally reimagined. It now boasted the 12-sided (dodecagonal) case shape and coloured sailing pennants that quickly garnered it a cult-like following and elevated the series to the legendary status it enjoys to this day. In the decades since, the Admiral has enjoyed grand attention as new and more visionary evolutions (always inspired by marine races and sailing) set the stage for this master of the seas timepiece.

Today, as Corum answers the call of contemporary casual navigators and lovers of the sea, it brings new versions to the forefront that are ready to go the distance. Each of the six versions boasts a dial with the three-dimensional Grenadier fendu motif that was totally designed in house in La Chaux-de-Fonds by the Corum team in 2019 and is unique and proprietary to the brand. Thus far, this dial motif has only been used on the 38mm and 45mm Admiral Automatic watches, so this marks a first for the Corum Admiral 42 Automatic.

Essentially, the six new versions boast two dial colours among them: a rich Mediterranean sea blue and a striking midnight black. Each dial colour is offered in three models: stainless steel case and bracelet; stainless steel case with colour-coordinated alligator leather strap; stainless steel case with 18-karat 5N rose gold bezel and crown and colour-coordinated alligator leather strap with triple folding clasp.

The sapphire crystal of each watch is treated with an anti-reflective coating, as is the case back that allows for viewing of the movement. Each watch is powered by the automatic CO 395 calibre that beats at 4 Hz and offers 42 hours of power reserve. Thanks to a screwed in caseback, the Corum Admiral 42 Automatic watches are water-resistant to 100 meters. They are a tour de force perfect for today’s lifestyles.

Founded in 1955, Corum represents creative and daring watchmaking. Corum uses an approach free of dogmas that enables a reconceptualisation of movement construction, its casing, and the artistic crafts that brighten the dial. Behind the many technical achievements (baguette movement) and aesthetic achievements (Coin Watch, Feather, Bubble), Corum continues the tradition of high-quality watchmaking that is ahead of its time.
Corum, established in La Chaux-de-Fonds, is opening itself up to the contemporary, street art, and classical art worlds, and in doing so attracting the attention of various trendsetters. At once disruptive yet respectful of its watchmaking heritage, Corum maintains its status of a niche brand aimed at demanding collectors of unconventional timepieces. Corum is currently based on four collections that embody its vision of 21st-century watchmaking: Admiral, Bubble, Golden Bridge and Heritage.
