I have been wearing my APROO over the last weekend, and it was the first time that I've spent a long time outside in the sun with it. Anyway, the numbers have actually gone from a light green colour to a darker green colour due to the exposure to the sun!
I have the version with a white dial and light green lettering - it actually looks like I've got grey numbers on my dial now, and I don't really mind it all that much, but just wanted to share it with you.
I'm afraid that I don't have a camera with me at the moment to show you the pictures, but thought that it was interesting enough to mention it.
