„According to Reardon, the two-tone colouring was applied intentionally as part of the Stern Creations dial making process. The 'night time' half of this sub-dial was varnished a shade darker than the 'day time' half. Over time, the darker half of the varnish has aged more aggressively on some examples, making the colour appear much darker than originally intended.“
