Launched in 1959 the Timex 100 series of watches had many sub-ranges including the Bayonet and Extra Thin (also called Wafer Thin). The apparent focus of this range was producing a set of slim cased watches with thinner bezels and more intricate dials.

The Timex 100 range covered every day watches and tank style models with most featuring a printed 100 on the dial.

These watches are highly sought after by collectors.
