With great joy, I present you this evening the latest addition in the Brellum family – Brellum Duobox Classic LE.4 Chronometer. Why this enthusiasm? Simple! Since the first Brellum Duobox Chronometer (powered by a calibre based on the Valjoux 7751), I was waiting patiently this triple calendar, moon phase. As you might have already guessed, the newest timepiece is powered by a movement based on the great Valjoux 7751. A review will follow after I will get my hands on it at Baselworld.

The brand’s emblematic collection, Brellum Duobox, is enriched with a new classic Limited Edition that will delight collectors eager for beautiful complications.

In addition to the chronograph function, Brellum Duobox LE.4 offers a triple calendar, with date, day and month indication, a day/night indicator and moon phase display.

Limited to 17 pieces worldwide, the COSC LE.4 movement is entirely decorated and adorned with a numbered rotor, treated in NAC Anthracite and a lunar symbol in Rhodium.
Brellum Duobox LE.4 comes with a hand made, large-scaled black alligator leather strap mounted on a decorated steel deploying buckle.
