The 16613 serves as the two-tone iteration of the iconic Submariner, offered with either blue or black dial and bezel combinations. Tritium was utilized on dials marked 'Swiss-T<25' until roughly 1998, followed by the adoption of Luminova and Superluminova for illumination. This specific example is highlighted by its exceptionally rare black Onyx dial.
