摘要： The invention concerns a timepiece with mainspring of the so-called fly tourbillon type, the tourbillon having a balance bridge (2) forming a cage with a collet (1) and a single protruding ball bearing (5) supporting said so-called fly tourbillon assembly. Said so-called fly tourbillon assembly is visible on the dial side (15) and is designed as an independent tourbillon module. Said tourbillon module is separable from the clockwork (13) by being detached on the rear side of the clockwork (13) and by being removed on that same side.
