Since launching its first proprietary caliber, with its innovative peripherally mounted winding rotor, in the Manero Peripheral timepiece back in 2008, Carl F. Bucherer has adopted “peripheral” design as its technical stock-in-trade. In 2018, the Lucerne-based watchmaker launched a timepiece with a world’s-first “floating” peripheral tourbillon, and this year it takes the concept to its highest horological execution to date in the new Manero Minute Repeater Symphony.

As you may have gleaned from its name, the watch features a minute repeater with a peripherally anchored regulator, another watchmaking world-first. What may not be as evident until a closer look is that its new movement, Caliber MR3000, also includes the peripheral rotor introduced in the original Caliber A1000 (and upgraded in the successor Caliber A2000) and the peripheral tourbillon of 2018’s Caliber T3000. As with the tourbillon cage of the latter caliber, the mechanism that regulates the beat of the repeater’s chimes is mounted peripherally on three low-friction ceramic ball bearings that ensure stability. This patented mechanism is designed to be visible from the watch’s dial side through a window above 6 o’clock. Furthermore, the repeater’s striking hammers are also on full display, through complementary dial openings at 5 and 7 o’clock.
The repeater also incorporates a protective mechanism that prevents inadvertent ...
