This is a fantastic conditioned Hamilton Boulton 6186.
I believe this has never been worn, other than a few minor marks on the underside (pictured, possibly from the point of engraving) it is immaculate.
The strap has no signs of being worn, no cracks from flexing, the movement is true and smooth. Purchased in the USA and given as a 25 years of service award from General Motors to Leamon Dudley Jr in 1994 it makes this watch at least 32 years old. Leamon Dudley is searchable in Google for historical references to the original owner of this watch.
It includes the original booklet (which hasn't been filled in so unmarked), the embossed tissue insert and a spare battery.
This item is precious for what it is. As such all shipping is via special delivery next day. I will ship overseas via UPS / Fedex / or Whatever is most viable and secure.
