If limitation limit from the bank, try open another few account from different banks..
Or u can deal it in the bank. Buyer can go counter to take any amount of cash... (not meaning millions). Under 100k should be no need early notice. Buyer take out cash n seller deposit back 
Just feel like one kind, if dealing in the bank, with lots of people in and out
Anyhow it save the hassle of multiple transaction if the watch is > 30k..
Thanks for input
