Hi, not sure if its the right place to ask? i bought a diashock today but cant find much info about model. I will upload pics shortly but to summarize its a winding model Sea Lion C22, the only other number apart from the serial that i can see is JI3086, nothing on the inside of the case back. The movement is not the same as other photos of this model that i have seen. It says seikosha 17 jewel 860, its date only. It was a non runner as i bought it but its now ticking away fine after some fettleing. The crystal although not badly scratched appears to have been bodged in without the gasket and isnt sitting dead center unfortunately . No strap was provided either.
