The invention relates to an assembly device, a method for obtaining an assembly device, a bracelet and a watch. An assembly device (10) for pivotally attaching at least two parts of a watch comprises a first part (1) and a pin (P) having means (7) to be mechanically connected to a second part (2). The first part (1) has a first friction surface (4) and the pin (P) has a second friction surface (5). The first friction surface (4) and the second friction surface (5) contact each other during pivoting movement. One of the friction surfaces (4, 5) has a surface hardness which is higher than the surface hardness of silica and/or feldspar. The other one of the friction surfaces (4, 5) has a surface hardness which is lower than the surface hardness of silica and/or feldspar. Effects of wear and stretch can be significantly reduced in this way.
An assembly device (10) for pivotally attaching at least two parts of a watch, the assembly device (10) comprising a first part (1) and at least a pin (P) having a means (7) to be mechanically connected to a second part (2), wherein the first part (1) has a first friction surface (4) and the pin (P) has a second friction surface (5), wherein the first friction surface (4) and the second friction surface (5) contact each other during pivoting movement,
