Abstract

1,254,256. Watches. TIMEX CORP. May 12, 1970 [May 28, 1969], No.23026/70. Heading G3T. In a watch regulator 19 comprising a pivoted arm 20 having an aperture 22 through which passes a hairspring 17 whose outer end is fixed at 18 to a bridge 16, contact between the hairspring 17 and the arm 20 is made only over part of the width of the hairspring by means of an arm contact portion 24. The width of the portion 24 is preferably less than one third of the width of the hairspring 17 and the arrangement is stated to permit the watch to maintain its initial rate. The contact portion 24 may be on the radially outer surface of the aperture 22, and may alternatively comprise a shoulder (28), Figs.3 and 3A (not shown) on a pin (26) fastened to the regulator arm.
