Watch Description
 Dial Case Material: 14k Rolled Gold Fill, Lug-Lug 36.4mm, 30.4mm width

Dial is cream color with lum numbers & Cathedral Hands & seconds bit

1930 was a big  transition year for Bulova. Without a doubt Bulova watchmakers had to do comparative analysis to determine cost & manufacturing efficiency & reliablility of their current & future products. During the late 1920s Bulova had great success with the circular 10AN caliber movement.  The 13AF movement was specifically designed for tonneau & rectanglular shaped cases. Normally, Bulova minute track & seconds chapter outlines are shaped to emulate the shape of the case.  This Lone Eagle II series watch is uniquely different from the Lone Eagle II powered by the 10AN movement  Notice the dial with the rectangular shaped minute & seconds chapter outlines and short stubby cathedral hour and minute hands.  The case frame was made quite different in order to accomodate the 13AF movement. This is not  a one-of-a-kind-watch.  There are at least three of the 13AF test bed watches on-site. The 13AF is apparently a very fine movement, but it didn't make the cut due to number parts & complication of assembly. Note the picture of the disassembled 13AF in Image 6.  It is conjecture on my part that if the 13AF movement had been accepted & used in tonneau & rectangular cases there would have been no need for the step-side design watches of the early 1930s.

The subject Watch is not showing the same engraving pattern as the advertised 'CHARLES'.

I'm thinking Wayne may have thought a mistruck 0 (which usually presents as a C) was a 6.

1930 Bulova Lone Eagle still for me.
