Solar Analog-Digital Alarm Chronograph

Resurrection was simple
The watch was in the safe of my Swiss bank for 8 years. Then on Easter 2002 I took a picture, I was just wondering why the watch was not kick starting when exposed to light, but had not time to really find out since I had to take many watch pictures from all the watches I had left behind in Switzerland when moving to Thailand.
In November 2003 I had time to open all the watches and remove dead batteries and take movement shots. I thought I would need a new Backup Battery 280-403 as indicated on the sticker on the back of the movement.
On Sunday May 23rd I was working when I suddenly heard that Alarm going off at 07:51 AM again. I had previously checked a lot of watches in my study and could not find an activated Alarm. I normally turn the Alarm off to save battery life. This time I shot up from my chair and followed the sound and it lead me straight to the Solar "Butterfly" Ana-Digi Alarm Chronograph on the bookshelf behind me. Wow! That was a surprise. I had always assumed that the watch was dead. Even the LCD display seemed to be dead.

Life span of Backup Batteries for Solar Watches
This leads me to the conclusion, that Backup Batteries for Solar watches, especially the Eco Drives have indeed a very long life span and will also survive very long periods of inactivity. This watch was in the dark for at least 8 years. This is the 3rd Citizen analog-digital watch that I had to jump start. The Wingman needed a little bit of work on the gear train (Rob B. did that for me), the Citizen Quartz Minute Repeater took some 2 hours on this Quartz Driving machine until it worked well again. This Butterfly did not take long to fly again, just a couple of turns and it kept moving. If you got a couple of Citizen Quartz watches collected over a couple of years, then a driver/magnetizer seems to be a very reasonable addition to your tool box.
