Back in 2009, I got myself a Reactor Trident watch. This watch had been my daily-wear watch, and while I do switch it out to wear other watches in my collection, I still return to this watch often.

One of the features of this watch is that it has a 10-year battery lifespan. Well, I just replaced the battery in April 2019. So yeah, you can say it does indeed have a 10-year battery lifespan. I did that myself actually, didn’t bring it in to any watch store to get the battery replaced. Couldn’t find a CR2012 (man, they’re rare!), and after doing a little bit of research, it seemed that other people have used a CR2016 instead of a CR2012 battery.
