Old Quartz Timegrapher ?

[rogart63]

Have a couple of old quartz watches .One Avia and a Tissot 430 . They are the first generation of the quartz movement . They are losing some time . I am thinking of servicing them . They are 17 jewels and have a balance like  ordinay movements . Their is even an escapewheel and a pallet fork .

My wonder is ? Could i use a Timegrapher to set the timing ? Don't now the lift angle if there is any but the frequency is 32768 hz . Or should i send them to Electric-watches.co.uk  ?

I have tried normal quartz on a Timegrapher but they just don,t register because they are to quiet. I as wondering if you could use a Timegrapher with pocket watches by attaching a length of wire to the stem & the mic pick up.

It actually did work .But i don't now if the readings are right . On this movement you can adjust both beat error and timing . I will take a picture . But i think i will send them to Paul for a check . This watch is ticking like a normal movement and has a sweeping hand .

Movement and Timegrapher reading . Don't now what to make of them ?

The watch in the picture is not a quartz watch it is a ESA 9154 Balance wheel driven by a transistor. The watch runs at 28,800bph amplitude and beat error don't apply. at least as far as the timing machine is concerned. You can find out more about their history at the link below.
