Corrosion.

You get what you pay for I suppose but this cheap watch that I've had for a reasonable while now is showing its age, maybe I should replace it so Olivia has a dressier Jimby to accompany her.
It gets harder to find a watch too as I've aged, I need to be able to easily read it and that eliminates a fair proportion of them, also it's no use watches with hands having a day and date dial as I just can't read them any more unless the light is superb. Just something pretty and simple will do.
I took this watch on my trip to Philippines in 2013 but I have a feeling it was bought around 2008, I've replaced the battery in its cheap Chinese movement a few times.
