Bought a new 16610 in August 1994 for $2065.
Easy to get back then.
Flipped it.
Bought a new GMT II 16760 in 1988 for $1465 and a white dial Ex II around the same time for about the same price.
Sold the GMT in 1994, never wore it. Traded the Ex II away.
Many of the watch traders I knew back then had a box of new or like new rlx watches for sale.
It was a lot easier to sell/trade watches back then...no internet educated 'idiot experts' to deal with.
Many of them today can recite every technical detail about the watch but can not figure out how to unscrew the crown.
