Brellum is what happens when you give a fourth-generation Swiss watchmaker free rein — and he decides to build watches the old-school way:
by hand, in-house, and to chronometer standards, one piece at a time.
This is independent watchmaking that actually delivers — clean designs, COSC accuracy, and some of the best-finished chronographs under $5K.
If you like your watches no-nonsense, no-middleman, and all-mechanical? Brellum’s your guy.
Founded in 2016 by Sébastien Muller, Brellum is based in Porrentruy, Switzerland, and operates as a true one-man independent workshop.
Sébastien comes from four generations of watchmakers and personally assembles, regulates, and tests each piece — often including a photo of
himself at the bench in your COSC certificate folder.
There’s no retail network. No mass production. Every Brellum is sold direct, built to order in small batches, and powered by top-grade Swiss calibers
— heavily regulated and certified.
Brellum is best known for its modern chronographs — both dressy and sporty — and its commitment to COSC certification across the board.
Flagship models include:
Highlights:
Because it’s a brand that actually builds what it promises — small-batch, Swiss-made watches, chronometer certified, and finished like something
twice the price.
You’re getting personal attention, serious value, and designs that respect tradition without feeling stuck in the past. And best of all?
You’re not paying for retail markup or celebrity endorsements — you’re paying for one guy’s hands on the movement.
Brellum runs a lean catalog with rotating limited editions and small production runs:
Expect pricing around $2,300–$3,500, depending on model and edition. Pre-owned? Still rare — and often sell close to retail because of the
small numbers and loyal fan base.
Brellum is one of those brands I genuinely respect.
Sébastien isn’t trying to reinvent the wheel. He’s just building classic Swiss chronographs, regulating them to chronometer spec, and finishing them
like a man possessed. The DuoBox? Easily one of the nicest Valjoux-based watches on the market. The Pilot LE? Great proportions, great legibility, great soul.
If you want real Swiss indie quality, backed by a guy with a loupe and a bench, Brellum delivers.
Delray Watch is always on the lookout for unique Brellum watches — especially DuoBox, Pandial, and limited edition Pilot Chronometer models.
