Abstract
A watch comprises a case, an electronic movement module inside the case, a piece of closed-cell foam inside the case, and a dielectric liquid filling the remaining voids of the interior of the case. The closed-cell foam compensates for thermal expansion of the dielectric liquid over a wide range of operating temperatures. Upon heating, the liquid expands and the foam is compressed. Upon cooling, the liquid contracts and the foam is decompressed.
