Your friend should be able to find a ref 3573.50 in the $3K - $4K range . . .

. . . in decent shape. This reference was in production for a dozen years or so. An earlier example should be less costly, probably saving enough to cover servicing thru an independent watchmaker.
Here's a pic I took ten years ago of a hesalite Speedy, probably a 3572.50:
This very watch today would trade in the aforementioned price spread, and at the lower end of the range fitted with a strap and deployant.
Servicing from an independent watchmaker would be ~ $500. A strap to taste, maybe another $300. Your pal should be able to get into a wearable sapphire sandwich for ~ $4K.
Let us know what happens!
Best,
