Having spent most of his professional life working for some of the world’s biggest watch brands, Sebastian Muller has decided to put his years of experience to use by setting up his own brand.
Using Valjoux movements and with COSC certification he has produced a tight collection of chronographs called Duobox. Without listing the numerous tests watches undergo at the Contrôle Officiel Suisse de Chronométrie (COSC), what it means is that that the movement in any Brellumwatch is adjusted to an average daily rate criteria of -4/+6 seconds per 24 hours achieving 99.99% accuracy.
This grey-dial Milanese-strap version is one of the best examples of the every-day qualities of the Duobox; named because the sides of the sapphire crystal used on the front and back of the watch come straight out for a couple of millimetres before doming to create a box effect.
At 41.8mm it has presence on the wrist but doesn’t dominate and the 6, 9, 12 configuration of the sub dials gives an uncluttered feel.
In fact, the level of detail as a whole on this watch speaks of a much-more expensive piece of kit, than Sebastian is charging his customers making it very desirable indeed.
Made in Porrentury, the cradle of Swiss watchmaking in the Jura, this pared-back “instrument” qualities of a chronograph are given a more refined look thanks to the addition of a grey dial and Milanese bracelet.
