This is my third post today unheard of, I'm a reader not a writer but I thought the posts were worth showing. I received this watch this morning spent ages setting it up after downloading an extensive PDF manual which to give you an idea took 20 mins. to print. All for naught as the battery died. Ah yes the watch is a Citizen 8410 Spacemaster radio-controlled watch. It came in its original box and as far as I can see pretty much minted. See what you make of it I haven't checked out its year of birth as yet its back in its box awaiting a new battery.
