In late 80s in my first private sector job I needed to make an impression so I bought a Rolex Air King from a catalog company in Wash DC, Marcus & Co. (I later found out they had gotten in trouble for selling used watches as new but mine was new). I paid a bit under $1000 for it. Loved the watch BUT it was made a year or two before they made the scratch proof crystals so I'd have to replace the crystal every 4 or 5 yrs. I sold it about 25 yrs later and got $1300. I would have gotten more except for that crystal. A $300 profit. Rolex is definitely a great investment.
