Fully functioning ultra rare WWF Superstars Tiger Electronics Game Watch- 1990

Recently found this when doing a clear out and was able to get it working again with a battery change. Was bought in 1991 but the wrestling game was only ever played a handful of times and the watch was never worn.

Therefore, it's remained in very good condition, with only some very feint marks and no damage or wear to the strap. No longer has the box but will obviously be sent fully protected. Happy to consider realistic offers. Having looked around, I can't find a used one for sale that is physically working. Therefore, that does makes it a rarity; which obviously adds to it's value.
