Abstract
PCT No. PCT/CH80/00072 Sec. 371 Date Mar. 16, 1981 Sec. 102(e) Date Mar. 3, 1981 PCT Filed Jun. 19, 1980 PCT Pub. No. WO81/00311 PCT Pub. Date Feb. 5, 1981.At the time of the casing of a watch in the back of which a diaphragm (19) is placed, an insulating and inert transparent liquid is caused to penetrate into the interior of the case by placing the whole in an enclosure under negative pressure. The air is exhausted, and the liquid in question comes to occupy the space included between the module (1) and the walls of the case. A small quantity of air contained under the diaphragm (19) expands under the effect of the negative pressure and causes this diaphragm to swell, which gives a compensating volume allowing thereafter the thermal expansion of the liquid within the case and without subjecting the walls of the latter to stresses.
