Abstract

1,263,278. Watches. R.C.A. CORPORATION. April 23, 1969 [April 23, 1968], No. 17487/71. Divided out of 1,263,277. Heading G3T. The Specification describes a watch similar to that of Specification No.1,263,277, but the claims relate to the use of a liquid crystal display and an integrated circuit for driving the display.
