Seiko SARN003. Retrograde days, GMT 2nd time zone, power reserve, date. One of the more elusive Seikos, with a rather interesting and unusual in-house movement. The chances of running into anyone who even knows what this watch is are remote. Chances of running into someone else who owns one are about nil. (Nobody in the U.S. other than a die-hard Seiko collector like me would pay Omega $$ for a Seiko.)
Although I own some Swiss watches, I really like Japanese watches a lot. This has been something of a "grail" watch for me. I've kept waiting to find one used, but they are so scarce, that they pretty much never come up for sale. I finally bit the bullet and bought one new. My new favorite in my Japanese collection.
