Independent Swiss watch brand founded in 2016 by fourth-generation watchmaker Sebastien Muller in Porrentruy, producing low-volume mechanical watches sold directly to clients with decorated movements and a strong emphasis on COSC-certified chronographs.
Open in The Dial AtlasThe Brellum entry in The Dial Atlas currently connects 1 cataloged reference across 1 family. The catalog records 2016 as its founding year and Switzerland as its associated country. The maker is organized here as a navigable set of family and exact-reference records. These counts describe the structured archive available on this site, not the brand's complete historical output.
Start with Duobox 39 (1 reference). Each family page keeps related watches together while preserving the reference codes, production periods, variants, and imagery that distinguish one execution from another. This makes the brand page a practical index for moving from a maker-level overview to the evidence attached to an individual watch.
Use the family links below to compare catalog breadth, follow production generations, and open the interactive Atlas view. Where the source data is available, reference dossiers surface case and dial details, movements, complications, nicknames, and current or discontinued status. The archive is designed to make both celebrated models and less familiar executions discoverable through stable, ordinary links.
