Important Notes to remember:
(1) The 3570.50 was made until 2015, this is when the new reference moonwatch (Legendary big box Version 311.30.42.30.01.005) was released. There will be a very small cross over period between the 2 references.
(2) 311.30.42.30.01.005 & 311.30.42.30.01.006 were the Big Box versions the sapphire sandwich version was the 006 cal 1863.
(3) The white gold moonphase was released to celebrate the 30th Anniversary of Apollo 11. Circa 275 pieces were made only.
** Some straight writing speedmasters were fitted at the factory with 861 movements destined for other models like the Seamaster. This has been documented and came to light by Extract of Archive requests that do not mach the reference number of the watch the movement is currently in. I know of multiple examples of this, thus an EoA was never issued.
