Love that. My brother-in-law owns a Seiko with the same type of custom stainless steel bracelet he had made in the Philippines on his way to Vietnam in the 70s.
Much appreciated! Yes, the genuine ones are hard to get and really hard to separate from the new ones that were made in 2000-2010s. It's great that you know of one from the original owner. I assume he was in the Navy and sent time at the Subic base.
