Watchlords

Citizen made two versions of a hand winding alarm watch, both using a Swiss design which was later used by the Russian maker Poljot. The first type was launched in 1958 using the 9800 movement with 17 or 21 jewels, and featured a ‘cricket’ style double case back. In 1964 a second version, this time with a single case back was introduced, using the same movement but now designated 3100 and with 21 jewels only.

With either a plain dial (movement number 3101) or a date window (3102), the early 1970s also saw several sports versions in the line-up and a couple had inner rotating timing bezels as well as the fourth hand for setting the alarm. These models formed part of the ‘Custom V2’ line and also featured black coated cases, reflecting the changes in design facilitated by new materials.
