Unstoppable? No.. I LOVE the skyhawk AT... But it is STOPPABLE... To pass this watch generation to generation here is what will go wrong eventually.
1. Eco drive- There is a an amount of charges the battery can take and eventually you need to mail the watch to citizens for replacement. Here is an email from Citizens:
The Eco Drive energy cell has an anticipated life of 40 years. Even after 20 years, the cell will maintain 80% of its charge capacity.
So... 40 years of life and then the battery needs replacement. What if Citizens is not around in 40 years? What then?
