The 6536-1 is a fascinating reference—one that packs an extraordinary number of changes into a four-year production period, which is why it remains one of the most collectible Submariners today.

Technically, the 6536 began life in 1954 as the transitional reference 6536/8, essentially a hybrid of the 6538 Big Crown and the 6536. Around eight variants of this transitional model are known, with the present example belonging to the second iteration, often referred to as the “Gold Depth.”

This watch retains its original dial, which still shows a strong Geiger reading. The lacquer has gassed out, as expected, but the gilt text remains in very good condition. The original gilt hands with radium lume show some oxidation—completely appropriate for a watch of this age. The hooked-5 insert dates from the late ’60s; aside from the bracelet, it is the only non-original component on the watch. The bracelet itself is a 7206 fixed-rivet with 75 end links and a clasp stamped 1/65. The case is in superb condition—polished in the past, but still extremely full.

The movement has just been serviced and is running at approximately +9 seconds per day with 225 amplitude.

These small- and big-crown references are becoming extremely difficult to find today, with totally original examples now achieving six-figure prices. This is a beautiful and honest example of one of Rolex’s most compelling early Submariners.
