History of Brellum

Brellum is a young independent watch brand founded by Sébastien Muller in 2016. They produce high-quality timepieces in a small town in Switzerland called Porrentruy. Sébastien is the 4th generation of the Muller family to embrace his calling.

He trained as a watchmaking apprentice but after that, spent 25 years dedicating himself to the acquisition of diverse skills in roles such as Product, Quality, or Production manager in a host of world-famous watchmaking companies. Throughout his career, he developed hundreds of watch models and produced millions of watches.

Brellum Swiss watchmaking came to be because Sébastien longed to return to his original watchmaking roots. He wanted to produce high-quality timepieces using quality materials and reliable automatic movements, fully adorned and officially certified by the Contrôle Officiel Suisse des Chronomètres (COSC).


Less than 500 Brellum timepieces are made per year, ensuring the high-quality Sébastien prides himself for. Brellum watches are only available for sale online, meaning that with no distributor or retailers, the brand can offer the very best value to its clients.

Swiss Made and COSC Certification

All Brellum watches proudly display the Swiss Made label. In addition to this, each movement of a BRELLUM watch has also been chronometer-certified to COSC standards. This label is reserved for movements that pass a constraining group of tests that determine each movement’s precision and stability. Only 6% of the Swiss watches have «chronometer officially certified» inscribed on the dial.

Fun Fact

The first letter of the Brellum name is the first letter of the village where Sébastien was born, Bonfol. The rest of the letters are an anagram of his last name Muller. A mythical creature called the Wyvern was the inspiration for the logo. It looks a bit like a dragon with wings and has a head like a snake with a precious stone called a carbuncle set in its forehead. The stone’s symbol is found on each of the Brellum’s crowns.
