The story behind this Carl F. Bucherer Patravi Calendar
Carl F. Bucherer is an independent company based in Lucerne. It creates timepieces designed for professionals and travellers. The Patravi Calendar model, reference 10629.03, follows in this tradition with a pragmatic approach to timekeeping. What makes this timepiece unique is its display of the calendar week via a central hand. Unlike traditional annual calendars, this watch indicates weeks 1 to 53 on its outer rim. This mechanism complies with the ISO 8601 standard used in international trade and finance. It allows for the visual planning of long-term activities whilst taking into account leap years. This level of detail illustrates the rigour of the Lucerne-based manufacture.
Case, movement and strap of this Patravi Calendar
The 18-carat rose gold case measures 42.6 mm in diameter. It features alternating polished surfaces and brushed sides. Its case middle is accentuated by thick, sweeping lugs and reinforcing rings framing the screw-down crown. Beneath the sapphire crystal, the deep blue dial reveals anthracite-grey highlights depending on the light. The layout of the information remains clear thanks to applied hour markers in solid gold. A large date window is positioned at 11 o’clock, a day-of-the-week display is situated at 9 o’clock, and a power reserve indicator is located at 6 o’clock. The watch is powered by the CFB 1902 calibre. This self-winding mechanical movement beats at a frequency of 28,800 vibrations per hour and offers a power reserve of 42 hours. Its sapphire crystal case back allows a view of the open-worked oscillating weight and the decorations on the bridges. The watch is fitted with a black leather strap with light-coloured stitching, secured by an 18-carat rose gold folding clasp. Water resistance is guaranteed to 50 metres.
