Collectors know how rare it is to find these Bell-Matics with all paperwork still present, especially the guarantee booklet and alarm instruction card.
This watch is being sold as found — it has NOT been opened, polished, serviced, or refurbished.
The watch winds and runs (buyer may wish to service due to age).
Crystal shows light wear consistent with vintage age.
Case and bracelet show honest patina and wear.
All components appear original.
This is exactly what collectors look for: an unmolested vintage Seiko with box and papers, not a watch that’s been polished into oblivion.
