Vintage Rolex Date Just Ref 1601 with A4 size Certification of Swiss Chronometer test report

This is an awesome report for the Date Just shown.



Date Nov 11, 1965 which is half a century ago, but the report shows that the time deviation was merely 3 seconds, so that could say what current mechanical advancement after 52 years is nothing better than this watch.

Or this watch was special made to meet such a nice performance.

For sales if you are interested to keep this time pieces.
