GMT-MASTER ll "misprint" and new 3186 movement

[Roger]

Just to throw a spanner in the works, I have just recently purchased a 16710 Coke GMT Master from an AD with a serial D6***** brand new as opposed to pre owned and the dial most definately has the parallel stick numbers and not the roman numerals.

This would mean that if the rumour is correct, then the 3186 movement was installed earlier than the "Z" series.
Accurracy is +2 sec per day which is identical to my dd but better than the Explorer 1 which is +4 secs.

All 3 watches are totally consistent with the same level of gain each day no matter what the circumstances.

3186 in a D series GMT11? now that would be nice.
