These are truly exceptional examples of early Timexes and must be very valuable...
I notice they also represent two of the major variations in dial layout.
First, the dials had all twelve hours marked with numbers as seen in the 1940's Timexes. Then, as dials and their numbers got larger, the ODD numbers were replaced by markers while the EVEN numbers remained.
A major variation occurs when only four of the numbers are left, the so-called "compass direction numbers" of 3, 6, 9, and 12. And finally, a purely abstract dial containing only 12 markers is derived.
I find myself drawn to dials that tend to break up the twelve hour time period they represent into four three hour chunks of time such as is done by the second of the watches Dorsey H. put in his response (the one with the black dial). This is probably because I tend to think of time in three hour pieces, especially when I am planning my activities. I prefer dials with the compass direction numbers present or, if the dial has only markers, dials wherein the compass direction markers are different or exaggerated compared to the rest of the markers.
I find dials that show only the even numbers or dials which contain 12 equally sized and shaped markers to be visually (and coceptually!) disturbing and I will not be adding them to my future collection...
