Change a Watch Battery

My watch stopped. It needed a battery. I was on a expedition in South America. How inconvenient..

Ready? Go!

I used a knife to start unscrewing the back but I guess you could use a watch-back spanner

Yep you'll put it back in a sec

You'll see a battery. Make sure you replace it with the right one. I also used compressed air to clean out the mech while I was in there.

You're done!!
