Vintage Eterna-Matic is definitely a way underrated watch.  They are exceptionally great in every way from case design, dial appearance, and excellent powerful mechanism.  The price value of the watch is not enough to balance the quality of the watch.  This Eterna-Matic calendar has been professionally serviced, working accurately and in very clean overall condition.  Powerful high-grade automatic movement with quick set date feature.  Signed original crown.  Just one great looking watch retaining its original minty champagne dial.
