Brellum Duobox 39 TC Moonphase Chronometer: A Compact Full-Calendar Chronograph
Brellum’s Duobox 39 TC Moonphase Chronometer brings the brand’s triple calendar and moonphase complication into a compact 39mm steel case, alongside a 12-hour chronograph. Its blue sunray dial displays the day, month, date, day/night indicator, and moonphase, while domed sapphire crystals, 100-metre water resistance, and a steel bracelet with an additional calf leather strap complete the design. The watch is powered by the COSC-certified BR-751 automatic chronometer, based on the Valjoux 7751, with a 46-hour power reserve and decorated movement visible through the exhibition caseback. Limited to 46 pieces and available directly from Brellum, it is priced at CHF 3,600 excluding VAT.
Buying Time Analysis: This release brings Brellum’s triple calendar and moonphase complication into a more compact 39mm chronometer, offering a limited-edition COSC-certified chronograph from an independent brand.
