Thanks mate my father wore one for decades, I got rid of it when he died as it wasn't working and there was a lot else to do. Always regretted doing so, my memory was of an elegant and very slim watch.AU super slim deluxe, the SU2209 puts in in soviet era so I don't think "model name" really applies, it was simply "deluxe" they made very few models and most used the same movement. it will be radioactive. The dial should say "deluxe" under Sekonda but wouldn't be surprised if it was never stamped.
Interesting from a historical "Made in USSR" point of view but the movement isn't the best and the workmanship was "interesting".
edit to add: found one on that well known watch site Etsy.
