Time keeping and watch making goes back a very long time. In 1761 John Harrison finally mastered an accuracy to plus/minus 5 seconds a month. The H4 was a pocket watch accurate enough to safely navigate the world oceans by. It was a major breakthrough.
In the 1800's watches were worn by women. They were immaculate pieces of jewelry, but lousy at accuracy. Men wore pocket watches.
All that changed in World War I when allied soldiers were fitted with luminescent wristwatches. Nocturnal battles could now be fought with total accuracy and coordination. By 1930 watches outsold pocket watches 50 to 1.
The one thing that watchmaking always came back to was accuracy. Our machine and data worlds rely on nanosecond accuracy to run right.
Sunrise and sunset are arguably the most significant markers of time in our daily existence, yet mechanical and quartz watch movements are incapable of capturing these time. They can only be calculated via complex astronomical algorithms. To fit it all on your wrist chip technology is an absolute must.
The YES watch collections bring accuracy to both man-made and natural time.
We will continue to service, repair and exchange batteries in our past collections. If you have any questions contact us at
