Replacement screw for Panerai stap - help please

[tomw2000]

I changed the strap on the wife's (40mm) panerai luminor last night.
She's had a brown croc strap on it from new and at the same time purchased a black croc strap - and wanted a change, so I put the black one on.

All went well and good, apart from the fact I lost the tiny weeny winsy screw that fastens the 'buckle' bit on. It's the newer type leather strap and buckle gubbins. So the ends of the strap which fasten to the watch came away easily with the 'new' tool. It was the screw at the other end I lost.

I don't suppose anyone has a replacement/spare screw or can suggest somewhere I could get one OR am I looking at a new atrap?
It's the smaller strap to fit the 40mm watch if that makes any difference.

I've looked all over the floor for the screw - but it's tiny and have had not joy yet!

I feared as much.

I shall hunt around on the floor a bit more and call the local AD

All sorted FOC, many thanks to the guys at Selfridges Wonder Room.

I just need to pop in with the watch and they'll sort it
