Well, I’m finally in on of these, as I want a slide rule in my collection. These are available all day between $220 and $250, so this is a nice little coupon rather than a great deal.
This watch, just like the alpinist, was discontinued in the great Seiko discontinuation of the late 1890’s. The factual documentaries found on YouTube go into great detail, but the fact these ancient relics of a bygone horological era are even made available to us mere mortals via manipulations of the time space field continuum is astounding. By my count, these have only been made available 36,728.2 times since the discontinuation a few centuries ago, so grab one while you can.
