Amanico's meticulous research into the Rolex GMT-Master ref. 6542 offers a rare glimpse into the production numbers and early history of this iconic reference. By leveraging a previously unseen Rolex document detailing US imports, he provides a foundational estimate of global production, inviting the community to contribute to a living census. This article serves as a crucial resource for understanding the true rarity and historical context of the "original" GMT-Master.

The GMT MASTER 6542 is a relatively rare watch. How many were produced, it is hard to say, but if you keep in mind that, according to Rolex is a document dated from December 1959, only 605 of them were imported in the US, we can reasonably guess that for the rest of the world, you can multiply per 4 or 5 the production and sales of this reference, during its life ( 1954 / 1959 )
The Rolex document in question: 




So, we had circa 2500 / 3000 ( once again, it is a guess estimate ) Rolex 6542 made, which is too much to say that it is rare, but which is nothing compared to the hundreds thousand 1675 produced.
It is said that the 6542 was unveiled at the Basel Fair in 1954, but the earliest I saw dates from 1955, with the serial number 112 xxx. 
If you have the evidence of a 6542 from 1954, please post it. 
The " youngest " 6542  was born in the last quartal of 1959. 
Let's see what we have, and please, feed the census. I achieved to find 100 different 6542.

-> Very rare 6542 " Underline " dial, no precision on the year, quartal and serial number, but if there were a few 6542 with exclamation dot, why not an underline?




->Another underline. Serial unknown, but from 1957: 



That is " all " I have, about 6542. Please, once again add yours or pictures you have of this extraordinary Rolex Reference and Milestone. 


Please note that all the 6542 featured here are not 100% correct. some had their hands changed, others had metallic or after market inserts, changed crowns and so on... But it is to give you an idea...

Best,

Nicolas 

About the Rolex GMT Ref. 1675

The GMT-Master reference 1675 is a significant model in the brand's history, representing an evolution from earlier GMT-Master references. It was produced for an extended period, allowing for numerous dial, bezel, and hand variations throughout its production run. This reference is notable for its introduction of crown guards, enhancing the watch's robustness and contributing to its distinct profile. It solidified the GMT-Master's design language, which would influence subsequent generations.

This reference features a 40mm case, available in stainless steel, yellow gold, or a two-tone combination of steel and yellow gold. It is powered by the automatic Caliber 1575, a chronometer-certified movement known for its reliability and a power reserve of approximately 42 hours. The watch is fitted with an acrylic crystal and offers a water resistance of 50 meters, suitable for everyday wear. The bidirectional rotating bezel, typically with an aluminum insert, displays a 24-hour scale.

For collectors, the 1675 is highly sought after due to its long production period and the resulting variety of configurations, including different dial types (gilt, matte), hand styles, and bezel colors (Pepsi, all-red, all-black). Its four-digit reference number and acrylic crystal are key characteristics that define it as a vintage Rolex. The reference appeals to those interested in the historical development of the GMT-Master line and the nuances of vintage watch collecting.

Tremendous work and passion for the GMTM! And the icing is you have in possession one of the not many thats still around. A friend took a pix of this at Cacciari Salvati, a jeweller in Italy, 2018.
