At the time your watch was made, the bracelets were extra cost options for almost all Omega models:
The dealer would have had a catalog showing the cross-matching of case reference to end-links to bracelet. I think the one of the two models shown above would have been correct for your watch, but not sure which one. BTW, the above picture is from a 1963 UK sales catalog. Your watch may be a little older than that.
An Omega Boutique (maybe Orlando or Jacksonville) could probably fit a modern bracelet, but since watches today are so massive, it might not be the look you want. And it will be very expensive.
eBay is likely the best place to look, but I have no idea what to tell you to look for.
Good luck with your search.
