Abstract
A retaining ring (17) which rests on the peripheral area of the dial (16), which is in turn bonded to a dial support (14). Several securing means (25) are on the one hand secured in the retaining ring (17) and on the other hand in a base element (13), such as an annular tool holder. This ensures a flat, smooth and lasting support of the dial (16) on the dial support (14). It also permits the simple assembly and dismantling of the unit composed of dial (16), dial support (14) and annular securing means (17) onto or from a base element (13).
