I was told by an expert that it was seen only 1971 catalog (no more specifics). But, he didn't discard it being produced earlier in that exact configuration. Most probably mistaken, then.Are you talking the salesman's catalog, or the one given out to Hamilton's customers?
The panda dial Chronomatic A appears in the 1969, 1970, and 1971 salesman's catalog(s).
(That Chron-o-matic model continues on for 2 more years, except it has black registers on a black dial, with a white tachymeter ring scale.)
Thanks. Sorry about that. My failed attempt of being diplomatic to the one that gave me the mistaken information. Strike "most probably"....
