Good morning everyone, I am sure this question must have been asked countless time, but being new to the world of collecting Omega Seamaster, I wanted to know more about the bezel of the 1957 Seamaster 300: * Was it painted black directly onto the metal with numbers painted in tritium over it? * Instead was there an insert? * If there was an insert, in what material was it made of? Thank you so much for any enlightened answers to these basic questions. Best,
