Clasp worn by time and blows breaking
This type of clasp is in two parts: the rectangle part is called the box, and the other, which includes a metal strip folded on itself that will "click" in the same box.
Its name comes from the noise made by the spring of the metal blade when it is lodged in the clasp, thus blocking the opening of the bracelet.

Stages of the repair

First and foremost, we will melt 18-karat yellow gold metal. It will be poured into a flat mold so that it can be shaped to pass through the mill.

Once laminated to the desired thickness, the metal plate will be laid flat and then we will be able to trace the figure to cut with scribing pliers, compass and square.
Our gold plate will make between 0.8 and 0.9 millimeters against 0.3 millimeters that made the old clasp. This will allow him to have a stronger hold over time and not crash.
The rectangle represents the lower part of the ratchet box before it is shaped. This cut should be perfectly parallel and its perpendicular angles for the smooth progress of the next steps.

The places where the sides of the box will be folded are then drawn with a compass and then filed with a triangular file so that the angle fits perfectly during folding.

The rectangle will then be annealed to make it more malleable and folded into right angles. Two internal solders will then solidify the folding and give shape to the beginning of the ratchet box.
Internal solders of the box
Two other plates will be soldered to the box, which will be cut and then filed down in order to have an almost complete box.

A last small plate will be soldered to the front of the box to create a stop. However, the gold leaf that will spring will be realized before, so that no error concerning the dimensions is made.
The ratchet slat will also be made in a laminated yellow gold, but on the other hand much thinner.
Rolled yellow gold before being filed and folded
The layout will be based on the internal volume of the box, then the plate will be filed as for the interior of it but with a much more pronounced angle.
Once folded, a small solder will consolidate the spring then the last plate serving as an abutment can be added.
Clasp box and ratchet
An "ankle" will be brazed on the top of the ratchet, it will be used to pressure the spring to open the clasp.
An opening will be cut in the upper part of the box for access to this ankle.
The technical part of the clasp is then complete.
