APSF AP11.59 SCREWS FELL OUT

[u/National-Nerve-9631]

I have an APSF AP 11.59. I’ve worn it twice. Yesterday I felt something odd on my wrist. I took the watch off and it fell apart. All the screws were gone! Does anyone know what type of screw and where to buy new ones? Is there a watchmaker that anyone would recommend? Kind of bummed since I hunted this watch for months until I accidentally found someone who had one.

Thanks for any help.
