Still my 50-year old Rolex Air-King Date, won 50 years ago this year, in a Rolex sales contest. Celebrating its Golden Anniversary in my possession, with the addition of a genuine Rolex 14-karat yellow gold bezel to spruce it up a bit.
No reason to change, actually.
New arrival from last Friday - 1962 Seamaster manual wind Cal 268. Appears to be all original and intact and came with the bill of sales and Omega warranty card from '62.
