A few years later, in 1959 the Explorer model 1016 was launched, it was the first Explorer to be marked 'Superlative Chronometer Officially Certified' on the dial, and was also the first to feature minute marks which went to the very edge of the dial. This example is one of this family and it comes in untouched conditions with sharp case and oyster riveted bracelet. The Dial is perfect aged with its black matte color and the well-know 3,6,9 indexes filled with tritium turned into a ocre color that identifies this model. It is important to underline that until the early to mid 1960s Radium had been used but being its potentially catastrophic effects were after replaced by the tritium, identified by the ‘SWISS T<25 or T-SWISS-T’ signature on the bottom edge of dial like the present lot.
