Hello - new to the forum. Been a watch collector for many years. My wife thinks I'm nuts, but there are definitely worse things I could do with my time. Just purchased my first O & W - a M-1 Diver. I am really surprised at the quality of the watch itself, especially how thin it is in comparison to other Swiss watches with similar movements. I am waiting for a rubber strap that I purchased from the Westcoast Time, then I will post some pics. Interested in learning more about O & W history. Thanks.
