Re: Vintage Seamaster Chronometers
In Response To: Vintage Seamaster Chronometers ()

: Have the standards for chronometers changed
: over the years?

No.

: Are the vintage Seamaster
: Chronometers (1960's) as accurate as those
: that are being produced today?

When new, the chronometers of the 1960's were required to meet the same +6/-4 sec/day chronometer tolerances as now. But today it is much more common for a fairly new chronometer watch to significantly exceed the specification. Many Omega SMP chronometer owners are enjoying accuracies of +/-1.5 seconds per day!

: Does the accuracy of mechanical watches
: deteriorate over time?

You are correct in thinking that the accuracy of watches deteriorates over time. This is mainly due to wear in the mechanism. They can be always be adjusted, but are still much more likely to vary in accuracy over time and positions.
