Rolex Submariner Explorer Dial

About this reference

The Rolex Submariner reference 6538 was produced between approximately 1954 and 1959. This specific iteration features an "Explorer" dial, characterized by Arabic numerals at the three, six, and nine positions instead of the standard baton markers. It utilizes a 37.5mm stainless steel case without crown guards and a prominent 8mm "Big Crown" signed with "Brevet." The watch is powered by the caliber 1030 automatic movement. Collectors value this reference due to its extreme rarity, as very few 6538 units were fitted with the 3-6-9 dial configuration. On the secondary market, these watches typically command prices in the mid-to-high six-figure range, often exceeding $500,000 depending on condition and dial patina. A notable auction result occurred in 2018 when a 6538 with an Explorer dial sold for $1,068,500, setting a record for the most expensive Submariner sold at that time.
