Any recommendations for place to change strap in So Cal?

[PN221]

I wanted to know whether you guys have any good places to change strap on my brand new AP.

I am in Orange County area and I am super nervous that someone will scratch my brand new watch and have heard just too many horror stories about AD's scratching watches being careless.

There is traditional jewelers but I don't know whether they are trustworthy.

Any recommendations would be greatly appreciated.

I am putting on the Grand Prix leather and Alcantara version so I hope it will look good.

Will post pics shortly.
