Need to locate a bracelet for this 1960's Constellation, Any help?

This was purchased as a gift for my son's 30th birthday, am looking for a bracelet for it but don't know what would fit or be correct, suggestions or offers appreciated!

After some searching that I should have done first it looks like the bracelet/link is 1037/522

The watch is a 168.004

Gold plated BORs aren’t very common but you can find them.
Be aware that BORs aren’t great for skinny wrists - so check your son’s wrist size.
I think these round case Connies look good on a leather strap.
I have mine on simple black but black lizard would look good too.

Thanks P, he does have a small wrist buy isnt appreciative of leather, I will find out if he intends to wear it alot or dress occasion type, TBH I fell in love with the watch which is now being serviced but I am more of a chrono type of guy

When finding one of the old BOR bracelets, they made some that were gold plated and some that were gold filled. The gold plated ones almost always have spots of the plating wearing off on them somewhere in my experience, and I would make an extra effort to get one of the hardier gold filled ones. It usually says whether its plated or gold filled on the folding part of the clasp.

I'd agree the getting a mesh bracelet might be a good alternative, but when searching for any kind of gold bracelet I'd look for NOS or vintage ones - modern gold plated metal bracelets almost always are a much more brassy yellow color and look really off when up against a vintage gold watch. Don't get a NATO strap that will rub the caseback smooth and definitely not one of the adjustable lug width bands with the spring loaded ends - they wear gnarly rings into the inside of the lugs that can really spoil the case over time!
