Part II: Presentation of De Bethune technical innovations

 

This is a copy of the presentation given by David Zanetta, detailing the various innovations created by De Bethune, most of which is the result of Denis Flageollet's genius.

 

Some of the notable slides include the one detailing the evolution of the De Bethune balance wheel. Most of them have been used in one production model or another, De Bethune constantly upgrades existing models with the latest innovations. For instance, the DB15 Perpetual Calendar, which has been in production since 2003, has seen its balance wheel evolve from something fairly conventional to the spider-like balance wheel shown in the presentation.
