Lug screw for 25807ST

[cc838]

Hi all, I recently acquired my first Audemars Piguet and it's a ROO 25807ST. Love it however it's not been getting much wrist time at the moment as it's missing one of its lug screw.

I have enquired with a watchmaker for a replacement part and they said they will need to order it from AP. Still waiting for them to get back to me on how much it will cost.

Topwatchparts has lug screws for the RO and ROO but I'm not sure if they will fit. Have contacted them and still waiting to hear back as well.

Just wondering if any forum members know where else I can source a good quality replacement lug screw and if anyone know if they are all the same size? The 25807ST has a smaller dial size so I'm not sure if that means they are using different size screws from the standard RO/ROO.

TIA
