5 second tick, must be that time again

My X-33 started its low battery warning in the form of a 5 second tick. I cant remember when I last did a battery change but must be at leat 3 years ago.

O.K lets get ready to go

Wow, 3 years worth god knows what. Now that’s disgusting.

Lucky the dust cover did its job

All cleaned up, battery changed and the watch reset and synced. Good for another few years.
