Hi SIFUs, i got a customer wanted to trade in his brand new Omega Seamaster Racing Chronometer ( model no 2269.5200 ) @ 40% off. However, my concern is he has lost his box, what he has is watch only. He promise this is not stolen unit and it can be sent for verification at Swatch Group, should I buy in this watch as it would cost me near to 12k ( brand new is 19650 ).
40% wo, it is definitely a good deal for Omega.. should I or anyone want to buy? tomorrow he will come again... please advise..

Thanks ..
p/s: what do u think if customer claims tat he lost the box...how come most of my customers dun wanna give me box?
