Timex were very successful with their electric watches; they were cheap movements and most of the models (calibres) were produced in large volumes. Surprisingly, the early models like the 67 were of moderate quality being fully jewelled and with polished screws although still with plated base-metal cases.

Their success in the electric watch market place almost certainly contributed to Hamiltons's financial problems in the late 1960's.

The Timex models show the technology evolution that took place during this short period:

• Moving Coil, Contact Controlled : the Model 67 introduced in 1962
• Moving Coil, Transistor Controlled : the Model 84 introduced in 1965
• Moving Coil, Quartz Controlled : the Model 63 introduced in 1973

The last type above (Model 63) is especially interesting; very few manufacturers produced a quartz controlled balance wheel and even fewer produced a moving coil version. Many thanks to Ian Fogden (Foggy) for giving me an example of this model!
