Brellum Throws Their Hat into the GMT Ring with the Pilot LE.1 GMT Chronometer

Brellum is an up and coming independent brand that prides itself on its rich familial history in watchmaking. Founder Sebastian Muller can trace his family lineage of watchmakers all the way back to his great grandfather who set up his very own shop in 1910. The rest, as they say, is history. Brellum exists today with the intention of continuing the Mueller legacy by producing highly-crafted timepieces that, not only present with a thoughtful design for the modern day wearer, but to pay homage to their family’s passion for traditional Swiss watchmaking. Their surname is an anagram in the brand’s namesake afterall. Recently, the brand announced a very limited run of a handsome pilot’s chronograph equipped with a GMT function with the Brellum Pilot LE.1 GMT Chronometer. The dial is where the Brellum Pilot LE.1 GMT Chronometer shows a whole lot of flash without straying too far away from the traditional pilot’s watch aesthetic. And by flash, I mean that opalin silver-now dial. From the images, it seems that this dial has its own character all on its own, displaying a luster against radiant lighting, and then a more toned down matted white in neutral lighting. All of the dial markings use black as the main color for unmistakable legibility including the minute track, 24 hour display bordering the outer portion of the dial, and applied numeral hour markers. The subdials take up dial real-estate at six, twelve and nine with a date window sneaking into the six o’clock s...

And 250 years later, it turns out he was right.

Bernhard Lederer Debuts the Central Impulse Chronometer Prototype

A member of the Académie Horlogère des Créateurs Indépendants (AHCI) since its founding in 1985, Bernhard Lederer is a veteran of independent watchmaking. Though known amongst collectors for having founded the brand BLU in 2002, Mr Lederer is more of a watchmaker’s watchmaker, supplying movements and complications via his company MHM (short for “Manufacture de Haute Horlogerie et Micromécanique”). Born in Germany but based in Switzerland for decades, Mr Lederer’s technical prowess is on full view with his latest creation – the Central Impulse Chronometer (CIC). Seemingly a mere three-hand wristwatch on the front, the CIC is a actually a significant accomplishment – and undoubtedly one of the most notable watches of 2020 from a technical perspective. The movement is equipped with a natural escapements as well as dual gear trains. The construction is familiar – Mr Lederer describes it as a tribute to the late George Daniels and his landmark Space Traveller pocket watch – but improved and refined with the addition a remontoir d’egalité constant force mechanism for each going train. Initial thoughts With seemingly everything already having been done in watchmaking, it is not often that we encounter a genuinely interesting – and improved – twist to an already uncommon escapement. Here Mr Lederer rejuvenates the centuries-old idea of the natural escapement, but elevated by the added complexity and performance gains of twin remontoir going tr...
