Bidding Range: $10,000
Omega Seamaster Ploprof
A high-quality brand only recently discovered by collectors, Omega has room to grow. "Three years ago 80% of the Omega watches from the 1970s would have been in the range of $1,000 to $2,500. Today the Ploprof, which is a very iconic diving watch, sells for $6,000 to $8,000," says Schaerer.
