I posted back in December a picture of gen SD for sale on an auction site with a discoloured 5 marker and from the posts (all copied below) learnt that it was an old SD with Tritium lume.
Well another has come up for sale on the same site and I can only assume it's a different watch as the other sold but it has the exact same issue - on the 5 marker.
So if it's a different watch why is it the 5 marker again?
Very curious. I can't get back to the old auction listing but for future reference, if it happens again, the serial number of this one is listed as U684***.
Might telephone them and check it is a different watch.
Here is the latest one for sale
