Abstract

A timepiece ( 100 ) including a case ( 10 ) including a middle ( 1 ), the top part whereof is closed by a bezel ( 2 ) and the bottom part whereof is closed by a back ( 3 ), a horological movement ( 4 ) mounted against the middle ( 1 ) by means of a casing ring ( 5 ), wherein the casing ring ( 5 ) comprises at least two clippable parts ( 50, 51 ) which hold the horological movement ( 4 ), the two parts being inseparable once mounted against the middle ( 1 ) when closing the case ( 10 ) of the timepiece ( 100 ).

First claim

The invention claimed is:

1. A timepiece including a case comprising a middle, a top part whereof is closed by a bezel and a bottom part whereof is closed by a back, a horological movement mounted against the middle by means of a casing ring,
wherein the casing ring comprises at least two clippable parts which hold the horological movement, the two parts being inseparable once mounted against the middle when closing the case of the timepiece,
wherein said two clippable parts respectively comprise at least one male part and one female part arranged such that they are clipped inside one another, said male part comprising a body and a head arranged so as to engage, by interlocking, with a recess in the female part, and the female part further comprises an opening disposed on the top of one of the clippable parts and opening out into the recess for receiving the head.

2. The timepiece according to claim 1 , wherein the two clippable parts are two semi-annular parts, a face whereof facing the movement including a groove which engages with a plate of said horological movement in order to guarantee the positioning and the holding thereof.

3. The timepiece according to claim 2 , wherein said clippable parts comprise an upper portion, a middle portion and a lower portion, said upper portion having said groove.

4. The timepiece according to claim 1 , wherein at least one of the clippable parts comprises a positioning lug arranged so as to engage with a notch in the horological movement to guarantee the orientation of the movement relative to the casing ring.

5. The timepiece according to claim 1 , wherein one of the clippable parts has a through-hole to allow for passage of a winding stem.
