This is an extremely rare
Eberhard & Co. three register chronograph,
over-sized (40 mm). The 18k gold case shows
little wear and the hunter caseback works properly. The dial is in
excellent condition and the chronograph functions are in working
order and the sliding lock functions well, movement runs fine.
I estimate the age of this
watch to be late 1930's and before the name Extra Fort was used. The
term 'pre Extra-Fort' is a phrase coined by collectors, classifying
watches that came before the Extra-Fort model, introduced
in the 1950s.This watch was actually their
first (and for the world) 3 register w/hour counter chronograph. The
watch was primarily used in military, motor sport, medical and
This Eberhard is executed using
the calibre 16000. These are not just rare; but especially rare in a
tri-compax configuration. This is a one button chronograph. The top
pusher manages all the functions; start, stop and reset. The bottom
button is actually a slider that locks the top pusher so that no
mishaps can happen. When the bottom button is slid up toward the
crown, the top pusher will not operate. When slid back down toward
the lug; the top pusher then is fully functional.
