Another interesting feature of this example is the tritium lume used on the hour markers, which has developed a warm patina over time. Patek Philippe used tritium between approximately 1998 and 2004, before transitioning to superluminova for their later pieces, between 2004 and 2006. Even if the tritium dials were used for longer, it is believed that Patek Philippe scaled-up production of the reference in the final two years, such that superluminova dials and hands are understood to be more common. Thanks to their tendency to develop patina with age, earlier examples have become particular sought after, displaying some vintage elements which are lost on later pieces.
