The Ascent is a spinoff of the Genesis, that was based on the Rolex Reference 6152 worn by Italian frogmen in the 1950s. The idea was to come up with an improved tool watch - one that's slimmer and therefore more versatile, and that's made of a material that would age well with minimal maintenance. Brass was chosen for the Ascent.
The Mk I Ascent, produced between 2013 and 2014, had Seagull manual winding movements, mineral crystals and came in two dial configurations; Arabic and California. The California dial comprises Roman and Arabic numerals and got its name supposedly from a California-based company that refurbished Rolex Bubblebacks with these dials in the past, when those were the rage.
The Mk II was produced in 2014 and 2015, and had improved durability and reliability over the Mk I which made them even better tool watches. While external dimensions and profile were unchanged, we introduced sapphire crystal and Japanese self-winding movements. Later releases had brass-sleeved crowns, whereas the earlier ones had ion-plated stainless steel crowns. There were two dial configurations, California and 'Supernova' - which was characterised by luminescent dot minute markers, used in an elusive prototype in the 50s that we have revived and modernised.
