The 6536-1 is a fascinating reference that packs a lot of changes into a slender four-year production period—this is why it remains one of the most collectible Submariners.

Technically, the 6536 started life in 1954 as a transitional reference, the 6536/8. This was essentially a hybrid of the 6538 "Big Crown" and the 6536. Around eight variants were made of this single model, with this one being the second iteration, known as the "Gold Depth."

This watch comes with its original dial, which still demonstrates a strong Geiger reading. The lacquer has gassed out, as you would expect, but the text has remained in very good condition. The original gilt hands with radium lume show signs of oxidization, which is expected for a watch of this age. The "hooked 5" insert hails from the late ’60s and, apart from the bracelet, is the only non-original component. 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 increasingly difficult to find, with completely original examples now regularly achieving six-figure prices.
