The name Sidereus comes from Sidus, the Latin for star. Sidereus is also a reference to the sidereal year, the time taken for the Sun, when observed from the Earth, to return to the same position in the sky in relation to the stars.

Brú na Bóinne, an area defined by a bend of the River Boyne, contains one of the world’s most important prehistoric landscapes. It was here that our Neolithic ancestors created vast stone and earth structures that marked events in the sidereal year. These megalithic monuments are inscribed with rock art and inscriptions that are a testament to a prehistoric peoples’ concept of the world: the flat earth, the firmament of the heavens overhead, the Sun, the Moon and the stars. The symbolic star of our logo is based on symbols found at these ancient sites.

Brú na Bóinne, our inaugural collection of watches, is a celebration of our ancestors’ role in the origins of horology and the marking of time at Newgrange, Knowth and Dowth for over 5,000 years.
