Update on the possible scammer last night (translated, this all happened in French):
Me (last night): Thanks for your time and help, but recent events have changed my situation and I have decided not to buy the watch for now.
> Him (today (Sunday) morning, 9am): Thank you for the update. I would also like to remind you that [in addition to bank transfers] we also accept payment by credit card.
There's just something about that reminder that made me a bit uncomfortable. Or am I reading too much into it?
Sod it anyway, the authorised Glycine dealer in Paris has almost the same prices and…is listed on Glycine's site as an authorised dealer. Should be much safer. Curious, though, that this guy is also clearly on his phone all day long — have never had anyone in France reply to emails within 2 minutes on a Sunday. They must get one hell of a commission.
