The day/night and leap-year indicators were removed from the 9 and 3 o’clock subdials, as found on the 3970 and 5970. Instead, they were placed within small apertures to the right and left of the date/moon phase subdial at 6 o’clock, taking inspiration from the leap-year aperture first used by Patek in the reference 3450 perpetual calendar launched in 1981. The day/night indicator transitions continually, from full white to full blue over the course of 24 hours, where the white color indicates daytime, and the blue color indicates nighttime.

The first variant, found in watches with reference 5270G 001.In late 2013, Patek discontinued the 5270G 001 and released a second dial type for the 5270G. Two different colors were introduced – one with a silver opaline dial, reference 5270G-013, and one with a blue sunburst dial, reference 5270G-014

The movement is based on the in-house, chronograph caliber 29-535 PS, originally launched in 2009 following five years of development. Within it, Patek utilized innovations leveraged from the ultra-thin, split-second chronograph caliber 27-525 PS, while applying lessons learned and improving upon shortcomings they found within the Nouvelle Lemania-based caliber 27-70 CH.
