Introduced in the 1980s during a period of revival for the brand under the stewardship of the Chaumet brothers and master watchmaker Daniel Roth, the Breguet Perpetual Calendar 3050BA is a watch that bridges the gap between classic design and modern functionality. Encased in a svelte 36mm 18k yellow gold case, it features the signature Breguet coin-edge pattern along the mid-casea cold-worked detail that speaks to the meticulous craftsmanship of the era. At just 8mm thick, the watch exudes an understated elegance, making it a perfect fit for formal occasions while still commanding attention with its intricate complications. The dial is a masterclass in balance and legibility, a hallmark of Breguets Classique line. Featuring a silver guilloche patterna hand-engraved technique that adds texture and depththe 3050BA displays its perpetual calendar functions with remarkable clarity. Four sub-dials gracefully present the leap year and month at 12 oclock, the day at 9 oclock, the date at 3 oclock, and a poetic moonphase at 6 oclock. Framing it all is a brushed chapter ring adorned with Roman numerals, complemented by the iconic blued Breguet hands that have become synonymous with the brands aesthetic. Its a layout that manages to pack a wealth of information into a compact space without ever feeling cluttered. This example is in exceptional original condition with a clean, early series guilloche dial and heavily tarnished case from years of never being polished.
