I bought a red submariner in south africa in 1975 for $250 i wore it every day for almost 40 years original dial and movement,chrystal was replaced and watched serviced once ,went through 3 straps,sold the watch on ebay 5 years ago sold for $13,000 within an hour the buyer reneged on the sale ,much to his dismay at the moment its probably worth $18,000 in fair condition.im glad that buyer cancelled the sale with prejudice,
