The Carl F. Bucherer Patravi EvoTec Calendar 18kt rose gold is equipped with the CFB A1000 manufacture caliber with a unique peripheral rotor system and black dial with luminescent hour markers and hands. It features a big date at 11 o'clock, confirming that this model belongs to the Patravi EvoTec family despite its round case. The small seconds function is indicated on the case by means of a disk. As this does not visually obstruct the indication of the weeks, it ensures optimum readability for the wearer. The heart of the watch is a mechanism designed and built entirely by Carl F. Bucherer: the CFB A1004, which adds a calendar, day of the week, big date and week indications to the firm’s in-house CFB A1000 movement. 

The CFB A1000 is a self-winding movement unlike any other being made today. The swinging weight that moves every time you do, automatically winding the mainspring, doesn’t sit on top of the rest of the movement as in other self-winding watches—instead, it rotates around the edge. That means there’s nothing to block your view of the fascinating machinery keeping time on your wrist (in most other self-winding watches, the oscillating weight always hides at least half the movement) and it keeps the whole thing pleasantly flat as well. An anti-fashion watch par excellence, the Patravi EvoTec Calendar is instead an elegant paragon of intelligent design, and a connoisseur’s homage to the romance of micro-mechanics. The CFB A1104 was designed from the ground up for long-term high precision, with a special two-armed system for locking in the fine adjustment of its timekeeping and protecting it from drifting out of adjustment over time. The EvoTec Calendar’s form-follows-function philosophy has guided the overall design of the watch as well: the advanced big date display (like the movement itself, an extra-robust in-house design) and skeletonized, arrow tipped hands keep everything elegantly visible, and the case design gives the watch a lean masculinity. Distinctively designed and impeccably engineered, the Patravi EvoTec Calendar is a watch that will only get better with time. Fitted on a black leather strap with 18kt rose gold fold-over deployant buckle.
