Swiss watchmaker Brellum has launched a new ice-blue dial variant of its Duobox Triple Calendar Moonphase chronometer. The limited-edition model features a sunray-finished dial and COSC-certified movement in stainless steel or titanium cases. Only 33 pieces will be produced.
Brellum, a small independent watch brand known for limited runs, has released the Duobox Triple Calendar Moonphase in an ice-blue hue. This follows the salmon-dial version introduced last April, which was praised for its complications and wrist presence. The new model swaps the opaline finish for a sunray dial, enhancing its visual appeal with polished Roman numerals, arrow-shaped markers, and luminous central hands coated in blue-emitting Super-LumiNova. The dial layout includes a moonphase and 12-hour totalizer at the bottom, running seconds and day/night indicator at 9 o'clock, and a 30-minute counter with day and month windows at the top. A small corrector on the case flank aids month adjustments. The watch measures 41.8mm by 51.8mm and 15.9mm thick, available in 316L stainless steel or titanium with a stainless steel bezel. It offers pump pushers, a signed crown, 100-meter water resistance, and a black handmade alligator-pattern leather strap with deployant clasp. Powering the chronograph is Brellum's automatic BR-751 caliber, a COSC-certified modification of the Valjoux 7751, with 28,800 vibrations per hour, 46-hour power reserve, and a skeletonized 4N-gold-coated rotor featuring a moon motif visible through a domed sapphire caseback. Finishing includes perlage, Geneva stripes, and blued screws. Curved lugs ensure comfortable wear despite the size. Limited to 33 numbered pieces, the titanium version retails for CHF 3,890 and the steel for CHF 3,690. Orders are available via Brellum's website.
