4 Automatic Sports Watches x2

Citizen’s largest vintage watches were sports models, made in the late 1960s and early 1970s. With cases of just over 40mm, they came in a variety of styles as well as the more 150m familiar divers. Here are four examples which illustrate the various designs:

The top three all have inner rotating rings – from left to right they are for rallying, diving and yachting. The lower model is the unusual Challenge Golf which has a high-beat movement and a scoring counter.

A further grouping of 4 can be made when the yachting watch, at top right, is joined by other models which use the same case:

Second from the left, the Seven Star Yacht Custom  is the odd one out here since it uses the earlier 25 jewel 5290 movement. The other three use the 23 jewel 7290 movement which replaced the earlier design. 

These sports models can be very hard to find these days – they would be a nice focus for a collection in their own right….

      Hi Rui,
      I’m afraid I don’t know the later quartz models so I can’t help very much. It might be better if you post a picture on the SCWF site, where there should be members who will be more familiar with the Promaster line.

    thank you, for your kindness with me

    Hi, I was just wondering how you determine year watch was made from serial/case number.
    I just picked up a Citizen with Sn 20507771 and 71-3716 right below it. Thanks

      Hi, thanks for visiting my blog. There’s information about determining production dates at the bottom of this page: https://sweep-hand.org/vintage-citizen-case-backs/. You do need to know what decade the watch was made in though – can you tell me more about your watch to help with this. If you can tell me what else is stamped on the case back, and what the dial markings are, we might be able to pin it down,
