A Reverso ring using
Calibre 101, which I was fortunate to acquire at an auction held by
Christie’s a few years ago.
These rings were made in various metal and stone combinations, in extremely small numbers (some claim fewer than 10), toward the end of the 1990s. One variant appears in the
Jaeger-LeCoultre 1998–1999 catalogue, but it is not mentioned in the corresponding price list.
Max Büsser told me that this was one of the first projects he undertook at
JLC, making use of the remarkable Calibre 101, while relying entirely on external resources to complete the product.
The ring has four faces: the dial visible in the photo, a full diamond pavé, a flat face, and a face with the crown, which is used to set the time and wind the movement.
