Seiko H558-5000 also known as Arnie. Dates from December 1987. Purchased from a retired watch maker along with few vintage watches and parts. Watch is in mint condition, all functions working fine.Rotating bezel, light and alarm works perfect. Glass has no scratches at all.I was told at the time all rubber seals along with battery replaced just over six months a go. Plastic shroud is not original but as good as if not better then the original brittle one so I was told. Photos are from the actual watch, what you see is what you are going to get. Thanks for looking.
