INTRODUCTION
Accuquartz"
Series 224
The Series 224 Accuquartz is basically an Accutron® Series
218 with some modifications. The most significant difference
is the addition of a Quartz Crystal Oscillator to an already
proven and established timepiece. Although some parts, regu-
lation and minor adjustments may differ, the Series 224 and
Series 218 are very similar to each other in basic servicing
procedures.
The basic tools and equipment necessary for servicmq the
Accutron Series 218 are also employed in servicing the Accu-
~. quartz 224. In addition, a Quartz Crystal Deviation Counter -
with 32,768 Hz pickup is required . ., When phasing, an I.C.
(integrated circuit) Phasing Attachment (Accuquartz Service
Kit #224/6601) is used in conjunction with the basic 218
movement holder. Also, an abbreviated meter scale is neces-
sary. (Accuquartz Service Kit #224/6602).
