Still enjoying my new (to me), 65 year old (approx.) Laco with a German made Durowe caliber 422, manual wind movement. Solved a problem with periodic stopping which I discovered was the result of worn bearings on the center wheel arbor. Now, all good. I love the dial.
What a beauty...very similar to the hamilton chrono-Matic in fact they look identical please tell me more.....
Buren were partners with Heuer and Breitling in the development of the Chrono-Matics and made the base automatic movement. By 1969 after they were taken over by Hamilton they were making all the Hamiltons too. Buren signed chrono-matics are very scarce, I think this is only the second photo I have seen of one.
