Back over a year ago, I wrote a pretty extensive write-up about my 6542 build. I really can't call this my build, because while I own the watch the build was a joint effort involving a lot of members here on the forum.
Since the original post I have made a few changes to the 6542, the first was a dial swap to an Ingod44 White dial. This is the 1675 dial that they were selling, as the face is identical to the 6542 dial, but this is a flat plate dial with feet, and the 6542 dial is a "pie pan" shape (like and upside down pie pan" with rolled edges that snap on to the genuine Rolex movement. this won't work on the 2846 movement. the other modification was to send the caseback to JMB and let him work his magic!! He engraved the Pan AM logo and the issue numbers on the case back.I also swapped out the rep stretch rivet bracelet for a gen 65201H Jubilee bracelet.
For those who have come along since the original post, here is a brief rundown of the components
Case : Ming Quy 6542 case this is a pretty accurate case, and it has a correct plated brass bezel and correct case back
Case back: Came with the case, and engraved by JMB This is not the flat "stepped" case that appears on later GMT's
Insert: JoeyB Lexan- these are the best around, if you build a 6542, you need to get one of these
Crystal: The case came with a genuine correct crystal, but it was cracked. I believe we used a Clark crystal
Dial: Ingod44 White 1675 dial
Hands: Small GMT hand is a rafflestime that JoeyB modified to be more correct. The other hands I believe came from a puretime 6542 that we were using as a donor watch
Movement: 2846 Slow beat with the GMT gears came from the puretime 6542
Crown: Gen Rolex
Bracelet: Gen Rolex Jubilee w/gen 55 endlinks, "A" code clasp (1976) This is not the correct bracelet, as the 6542's came with rivet bracelets and were probably changed to 7836 bracelets at service, but this is and old comfortable bracelet and wears well.
That pretty much sums up the build, lots of folks were involved in this, as there were numerous problems along the way, several were movement related, as the 2846 is a pretty old movement and this one required several trips to the shop to get right!
Here are a few photos I took today. The last one is a pair of Rolex GMT's the black dial is a gen 16750 which is the second generation after the 6542 so you can see the progression of Rolex GMT's from 1958 to 1983
The watches are shown with some of the PanAm memorabilia that I have accumulated. Thanks for looking
