First I would like to say that although I am a first time poster, I have been lurking in these forums for the past couple of years. I really appreciate all the information and insight I've gleaned from these threads and have made two watch purchases based on what I've learned here. I am currently the proud owner of a Seiko 5 Sports (first mechanical watch), my great grandfathers Timex Self-wind (saved from going to goodwill, circa 1959), and also a Seiko 6139 ("Pogue" circa 1976). I hope to own an Omega Speedmaster Professional someday but that's a conversation for another day.
The reason I'm positing is to get some insight on a watch I picked up this past weekend. It's an obvious "homage" to a Cartier Tank, but I can't seem to find any information about the watch based on its markings. The dial appears to be enamel with the l/L/S F A below the 12 position, SWISS below the six position, and has blue hands. The case back is plain with the exception of a five digit number. The crown has a blue stone/glass cabochon. The inside of the case back is marked "S. KOCHER SWISS" and has a three digit number on the outside rim. The movement is marked "17 JEWELS SEVENTEEN S. KOCHER UNADJUSTED SWISS."
Based on my research, my best guess is that this is a generic homage tank watch circa 1950s. I'm curious to know how close my guess might be and would really appreciate any insight you all can give.
Thanks for your help,
