This complicated Heuer chronograph impresses at at first sight with its attractive enamel dial, its considerable size and extremely remarkable state of preservation.

All chronograph steel parts are finely ground, all bridges and cocks are beveled. The 19 lignes movement with a diameter of 42.10mm operates at a frequency of 18,000 beats per hour and is equipped with hack feature. It is adjusted to two positions and has Geneva stripe decoration. The monometallic screw balance has Incablock shock protection and gooseneck fine adjustment. The monometallic screw balance is equipped with incabloc shock protection and a wishbone regulator fine adjusting device. This watch has been carefully preserved and is therefore in very good optical and technical condition.
