I just purchased this GP alarm watch circa 1960s. I'm waiting for a new brown crocodile strap for it. It appears to be in original condition with some age spotting on the dial, but I like the silver dial and classic looks of this vintage watch. Here are a few pictures taken with my phone. I'm sorry for the poor quality.
Very cool, well that she makes it even better. Who knows how many of the 900 are left. I think they made it in gold filled too right? I think most would prefer the steel so like I said good catch.
Big congrats!!! I used to have a couple of those, but flipped them during my early stage of vintage watch collecting.
Very nice and unusual piece with the lack of an alarm hand giving the dial a nice simplicity. Maybe our resident vintage advert researcher @Vitezi can dig up some literature related to your watch.
