Patravi ChronoGrade (10623.08)

The Carl F. Bucherer Patravi Chronograde Flyback Annual Calendar stands out because it packs multiple complex functions into one timepiece — a flyback chronograph, annual calendar, big date, power reserve indicator, and a retrograde hours counter — all in a finely engineered Swiss automatic movement. This mix of practical and mechanical features makes it both useful and fascinating for watch lovers.

The dial of this watch is busy but well-balanced, with a big date window under 12 o’clock, a month display between 4 and 5, small seconds, and chronograph counters laid out clearly for easy reading. The retrograde hours counter adds visual interest as it sweeps across its arc and then instantly returns to start when the chronograph is running. The case is substantial at around 44.6 mm in diameter and feels solid on the wrist, with a sapphire crystal on both front and back giving you a clear view of the dial and movement. The bracelet or strap (often high-quality alligator leather) pairs nicely with the case, and the sapphire crystal has anti-reflective coating so the dial is easy to see in all light conditions. The water resistance is about 50 meters, enough for everyday wear but not for swimming.

Inside this Patravi Chronograde beats the CFB 1902 automatic movement, a complex self-winding caliber that runs for about 42 hours when fully wound. It combines a chronograph with a flyback function (letting you reset and restart the stopwatch with one push), an annual calendar that adjusts for different month lengths and only needs correction once a year, a big date display, and a power reserve indicator. You can also enjoy the retrograde hours complication, where the hours hand jumps back to zero at the end of its scale — a fun mechanical feature not found on many watches. The movement uses a good number of jewels and offers reliable everyday performance.

The Patravi line comes from Carl F. Bucherer’s long Swiss watchmaking history, a brand founded in 1888 in Lucerne that has built a reputation for combining traditional craftsmanship with modern engineering. The Chronograde itself is part of the Patravi collection, known for technical sophistication and bold designs that stand out from simpler dress watches. Its annual calendar and flyback chronograph show the brand’s commitment to useful, advanced complications that appeal to enthusiasts who appreciate mechanical complexity as well as everyday practicality. Over the years, the Patravi ChronoGrade has attracted attention for packing multiple high-end functions into one watch and remains a notable example of Carl F. Bucherer’s work.
