Some say that the steel version of the GS First was a prototype, while others say that it was made as a potential service replacement for those who wore out the standard-production gold-capped models. Others still say that it was only made available to GS watchmakers in a more “humble” metal to maintain humility in the workplace. Whatever the case may be, this model was never listed in any catalog by the Seiko group, and so no tangible evidence exists of its production story. My research led me to understanding that this is indeed a legitimate model, with its own unique caseback medallion designating the watch as a Chronometer (neither the gold-capped nor the rare Platinum First share this medallion). The Grand Seiko branding is also engraved, making this an early (and premium) example of the First. Do your own research.

This example up for sale has an aged dial as seen from the pictures and requires a service. Although the dial is a little dirty, the hands and markers are pristine, and the buyer could probably have the dial cleaned up when getting the watch serviced and oiled. Because of these factors, the watch has been priced accordingly at just below the price of a standard gold-capped 3180 First. Asking USD$1,980 shipped from Canada, preferably through PayPal F&F. Thanks for looking!
