Thank you, Heinz. The egg timer comment was partially in jest and in reference to a Hamilton ad concerning the Chrono-Matic and "uptight, business men who were fussy about their three minute eggs." I've done so much research on this watch in the last couple days, and I have found several suggestions concerning three minute applications. I did say military, but what I read had more to do with aviation and navigation. I'll try to locate that and share that info. The telephone call timing makes the most sense. I read that as well, but appreciate you confirming that information. I've considered that Hamilton may have released a few Chrono-Matics under the Buren name in Europe, as this would've been a more familiar brand to the European consumer, but I can only speculate. As far as I can tell, this dial was never released in the U.S. Market. I would really just like to determine if it's European domestic market, or possibly even rarer.
