Hublot bezel 'H' screw - does anyone know the length for the 6pm one as mine's fallen out

[danholmes007]

Hi,

Does anyone know the length for the H screw in the Bezel of a Hublot big bang for the 6pm screw. I think its either 5mm or 6.5mm but can't tell and need to order from the US so want to get it right first time.

 

thanks
