Tag Heuer Men's s87.806 Waterproof Watch, Needs Servicing

I am selling this as I think it is time to move on.
I have had this watch for many years and it has served me well.
It needs a service and is currently not in working order. Although the strap is fully present it does need re-connecting to make it whole again.
It is a lovely piece but I have now upgraded and no longer need it.
Please feel free to ask questions.
Many Thanks &
