... To see your perpetual calendar clocks and watches in action, as the date hand changes over not 1,2 or 3 days but FOUR days over to 1st March!

I have a beautiful antique Seth Thomas Office Calendar 6 Clock. It is a beautifully made, spring driven, twin dial, manual wind 8 day power reserve fully perpetual calendar clock. The calendar needs adjustment only once in 400 years!

The one I have was made in the early 1900's and very accurate!
