Abstract
1287643 Clocks and watches EBAUCHES SA 23 Feb 1970 [17 March 1969] 8615/70 Heading G3T The matter described is substantially identical to that of Specification 1287642 but the claims relate to the use of a gauge, substituted for a ratchet wheel, in setting the elastic loading of a retaining pawl and hence the relative phasing of the driving and retaining pawls.
