Brellum Duobox Pandial Chronometer

Young Swiss watchmaking firm Brellum has this rather unsual name for its new expanding series of watches. This new sports chronograph is distinguished by its strongly contrasted dials.

Like the previous models in Duobox collection, this new model features two domed sapphire crystals as well as the slightly domed dials with diamond-cutted indexes. The first crystal protects the dial and allows an optimal reading thanks to its anti-reflective treatment. The second crystal fitted at caseback allows the owner to admire the automatic movement in detail and at all times.

Its stainless steel case is fitted with an aluminium tachymeter bezel and has a total diameter of 43.00mm. It houses the legendary Valjoux 7750 self-winding chronograph movement. The movement is entirely decorated and officially certified chronometer by the COSC.

Production of the Pandial collection is limited to 299 pieces per year. The watch is available with leather/fabric straps or Milanese bracelet. Every timepiece is delivered with an additional rubber Nato strap.
