Title (EN) ELECTRONIC WRIST WATCH AND PROCESS FOR CASING SUCH WATCH
(FR) MONTRE-BRACELET ELECTRONIQUE ET PROCEDE D"EMBOITAGE DE CETTE MONTRE
Abstract: front page image
(EN)During the casing of a watch wherein a membrane (19) is arranged in the bottom thereof, an insulating and inert transparent liquid is introduced inside the casing while placing the lot in a housing under depression. Air is evacuated and the liquid fills the space comprised between the module and the walls of the casing. A small quantity of air contained under the membrane (19) expands under the effect of the depression and blows up the membrane, providing a compensation volume allowing then the thermal expansion of the liquid inside the casing without subjecting the wall of the latter to a mechanical effort.
(FR)Lors de l"emboitage d"une montre dans le fond de laquelle est placee une membrane (19), on fait penetrer un liquide transparent isolant et inerte a l"interieur du boitier en placant le tout dans une enceinte sous depression. L"air s"evacue et le liquide en question vient occuper l"espace compris entre le module (1) et les parois du boitier. Une petite quantite d"air contenue sous la membrane (19) se dilate sous l"effet de la depression et fait gonfler cette membrane, ce qui donne un volume compensatoire permettant ensuite la dilatation thermique du liquide a l"interieur du boitier et sans soumettre les parois de ce dernier a des sollicitations.
