Reference:6074: Difference between revisions

Line 135:

The 6074 sits in the automatic Ovettone movement generation, a self-winding Perpetual calibre with centre seconds and a date that creeps to the next numeral over the minutes either side of midnight rather than snapping over. There is no quickset and no shock protection; the instantaneous change arrives with Cal. 1065 in the 6604 and 6605 of 1956–57.

The precise calibre in the 6074 is not published by name. The Ovettone references either side of it run the A.295 and its 29.6mm evolution the A.296, and the sources disagree about where the changeover falls: the reference literature puts the A.295 in the 6031 and the 6075, while Le Monde Edmond, working from Phillips photography, gives the 6075 an A.296. Neither reading has been tested against the 6074, whose movement number Goldberger does not record. The 1992 Antiquorum catalogue entry for the watch (see Production outline) does give a movement description, independent of Goldberger's later book: "9 3/~~4'''~~ rhodiumed, 17 jewels, lever escapement, Superbalance balance adjusted to 6 positions, antishock system, self-compensating Breguet balance-spring, micrometer regulator." That's a ligne size and finishing description, not a calibre name, so the honest statement remains that the watch belongs to the A.29x family without a documented calibre reference. The [[Reference:Movements]] page holds the wider lineage.
