An Explorer dial ref. 5512 Submariner from 1961. Within early crown guard Submariners, this 5512 represents the rapid iteration Rolex sustained at the start of the Submariner. Featuring a coveted gilt, exclamation 3-6-9 Explorer dial (Variant I), this is amongst the most desirable Submariners made. This is the last reference to combine the thorough legibility of a 'Explorer' dial with the Submariner's utilitarian charm, not to mention the allure of PCG crown guards or warm, amber plots. Well-preserved, this early 5512 Explorer dial is amongst the most significant and alluring Rolexes made.
