This Week’s Featured Watch #12 – the Uni Auto Dater

Last week’s feature was the SM, using one of the early swinging weight type of movements Citizen introduced to replace the Jet. In fact, it was the second model to use this type of movement – it was preceded two years earlier in 1963, when the ‘Uni Auto’ was launched. Two versions were produced, the Uni Auto with a plain dial, and the Uni Auto Dater with date window. The movement numbers are respectively 1400 and 2400, both with either 17 or 19 jewels. My example is the 17 jewel autodater:

Made in April 1965, the back is plain:

Inside, the 2400 movement is simply signed, with no detailed finishing. Typically for that time, the watch runs at 18,000bph and unlike the later SM models, there is no date quick-set mechanism:

Citizen gave the Uni Auto’s a unique logo:

And this model is rated to 40m:

The original retail price of these ranged from JPY5,500 to JPY7,200, so were relatively inexpensive watches, presumably to have mass market appeal.
