A lot of the charm of vintage watches comes from the changes which have taken place in the watch over time, which express its connection to the past, and ring the nostalgia bell for enthusiasts, even if they hadn’t actually been born yet when the watch was born. These changes, however, often travel along with a reduction in functionality, which is most often seen in the deterioration of tritium or radium dials. That lovely faded color gives a rich warmth to a vintage watch, but of course, you can’t tell the time in the dark. Modern Super-LumiNova will, as far as we can tell, light up the night almost indefinitely without deteriorating since unlike tritium it doesn’t rely on radioactive decay to produce light, and the new 222 is pleasantly readable under low light conditions.
