Patravi EvoTec PowerReserve by Carl F. Bucherer

The deliberately understated, modern design concept of the Patravi EvoTec PowerReserve is emphasized through the geometric index marks that echo the gently curved shaping of the case sides. All in all, the dial of the Patravi EvoTec PowerReserve really does fulfill all the Carl F. Bucherer criteria for perfect legibility.

The sensational cushion-shaped case in which the first versions of the Patravi EvoTec PowerReserve are to be presented is the perfect vehicle. It is already an esteemed hallmark for the launch models of Carl F. Bucherer timepieces based on the EvoTec Manufacture Concept. The bezel and crown, both in black rubber, render the case – made from either cool, modern stainless steel or elegant rose gold – even more striking and distinctive.

These watch cases owe their iconographic character not least to the design elements that characterize the Patravi collection, such as the curved strap bars and the distinctive crown protectors. The CFB A1000 – the perfect platform. The movement in the Patravi EvoTec PowerReserve is based on the CFB A1000 Manufacture caliber. A caliber which, thanks to its innovative technology and advanced design, is the perfect expression of the EvoTec Manufacture Concept by Carl F. Bucherer. The characteristic feature of the CFB A1000 is the peripherally mounted and bidirectional winding oscillating weight, which supplies the gear with power.

This mounting is one of the most demanding and challenging creations of all, which is why it could not be satisfactorily created before now. In contrast to the central rotor normally used, which always covers half the watch movement, the peripherally mounted oscillating weight allows an open view of the accurately ticking microcosm and thus combines the aesthetic value of a hand-wound movement with the comfort of an automatic winding. It also means that the caliber requires less height and that the construction of the functional modules on both sides is possible.

Carl F. Bucherer was able to realize this construction as a result of mounting the rotor on DLC-coated rollers (“Diamond Like Carbon”). Carl F. Bucherer fitted these rollers with new, maintenance-free high-tech ball bearing mountings with ceramic ball bearings. These ball-bearing/roller assemblies are mounted on rocking bars. The rollers are very precisely positioned by means of ingenious springs, and the rocking bars can be precisely adjusted by means of eccentric cams.

This dynamic shockabsorption mechanism is patented under the name “Dynamic Shock Absorption” (DSA), and is a highly efficient and reliable system. In the event of a sharp impact, the walls of the bridge reduce the radial displacement of the oscillating weight. The innovative potential of the CFB A1000 is by no means exhausted.

A further invaluable feature is the patented “Central Dual Adjusting System” (CDAS), an intelligent precision adjustment method with a central control element. The balance and escapement require adjustment only once, and thereafter remain secured in position. This provides effective protection against shocks.

Carl F. Bucherer of course also breaks new ground in terms of decorative finish. The bridges and bars at their various levels have matt and brushed surfaces with diamond-cut facets. The aesthetic appearance of other components is reflected in their matt, brushed or polished finish.
