Can someone give me any info re my tag purchased approx 1986/87. It's a 1000 series black with phophorous greenface (which illuminates nicely in the dark). I don't suppose it's worth anything now but it would be nice to know if it's rare. The strap is also black, although now as i've owned it for the past 17yrs the black is rubbing away. I would say tho that this watch is supremely accurate.
