Does anyone have any information on Ref. 4900, more specificaly 49006.0.56.617? The watch in question is stainless steel w/ rose gold bezel and crown, black dial with Ferrari prancing horse on yellow shield, center seconds, date at 3:00, automatic. It looks genuine but has a dubious provenance, Bangkok via Singapore. Can any G-P specialist tell me what caliber movement it is or anything about it's production
