When I bought my 6542, it came with a service aluminum insert and a " - " crown. I first changed the service bezel for a correct bakelite insert. That was a huge addition, as you can imagine. Then, I received the original " red chronometer seal ". And three days ago, I was gifted a " + " crown! Here


The GMT Master reference 6542 was introduced in 1955 as a specialized tool watch for pilots. It is notable for its dual time zone complication, achieved through a rotating 24-hour bezel and an independently adjustable 24-hour hand. This reference marks the initial iteration of the GMT Master line, establishing the core functionality and aesthetic that would define subsequent models. Its development addressed the need for a watch capable of displaying multiple time zones simultaneously, a requirement that emerged with the advent of intercontinental air travel.
The 6542 features a 38mm stainless steel case, housing the automatic caliber 1036. This movement provides a power reserve of approximately 42 hours. The watch is fitted with an acrylic crystal and offers a water resistance of 50 meters. Early examples of the 6542 are distinguished by a Bakelite bezel insert, which was later replaced by an aluminum insert due to durability concerns. The dial is typically black, often featuring gilt printing on early examples.
This reference holds significance for collectors as the foundational model of the GMT Master series. Its distinct characteristics, particularly the early Bakelite bezels and specific dial configurations, are key points of interest. The 6542 represents the original design intent for a pilot's GMT watch, making it a reference point for understanding the evolution of the model line. Variants exist with different bezel materials and dial details, contributing to its collectibility.
Bill is such a nice friend. Little things like these make life worthwhile !! Enjoy her in good health
And a wonderful watch, of course.
Of a fantastic specimen 😍😍👍🏾 Thank for sharing your great story, my friend. Cheers
but what are the differences of the hour, minute & second hands? your existing hands VS the correct one. cheers
The minute hand is longer and reach the minute indices ring. The second hand is white and lollipop. The difference for the hour hand is way more subtle, I agree.
I am very happy to read stories like this 🙏 Thank you for sharing ! Looking forward to your final final version of your 6542, Nicolas warmest regards
