Hey all. Trying to ID a vintage Swiss wrist watch I saw yesterday. The dial had lost it's name and was only marked as 17 Rubis Shock Resistant The movement was a pink 17 jewel ETA hand wind, so an earlier movement. The case was full steel and on the case back was a crown logo not dissimilar to the Rolex logo. The crown was also on the movement. I've seen this logo before and cannot recall who the company is and looking online has not helped. Any ideas?
