·Hey OF,
The photo posted below represents the following.
The Dial is silver sunburst with yellow gold stick hour markers and a small horizontal line below "SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED". The underline was fitted with 1960-1964 Rolex dials. Many collectors agree this special underline signifies a change from radium to tritium lume material. Some dials are transitional in this change. Honest vintage Rolex dials sporting this small horizontal line are extremely rare.
I've read a variety of reasons regarding the underline from centering the text for early printing to lume transition. I've seen underlines under geiger counter vs non-underline and there is a clear difference in radiation. I've also seen full tritium underline dials.
Curious what OF has to say about this topic. Wishing you and your family a wonderful 2020! Hold on to those new year resolutions!
Best,
Thomas
