I'm getting a tad confused  . First there was the venerable 321 and then the 861 going onto the 863 with the 1861 and 1863 coming into play. The difference between the 321 and the rest and the passage from pink and yellow gold to rhodium is easy enough to follow but what is the difference between the 1861 and 1863 movements please? My fellow amigos, the Speedy Masters in Arms, GJ and Fr John may throw further light on this I'm sure. I've looked up Chuck's words of wisdom but can't quite precisely locate what I'm looking for. From where I'm standing ( sitting even ), it's pretty much the darker side of the moon  . Thanks in Advance guys  Enjoy your weekend ZIN  |

Pff...difficult question Zinster...  My guess here it would also be a cosmetic change, a jewel more or less. This site has LOADS of answers :http://www.speedmaster-mission.net/ Omega made so many different small changes to the movement for improvement, it's hard to keep up with.. Maybe Fr. John knows the answer to this one.. |

Well I know of the additional jewel but I thought that was in the 1861. Omega also used a plastic material for one of the parts because it wore well and lubricated more evenly or better in some way. I think this may have been the Delryn Brake. I do know that the part was changed to its' metal equivalent for the sapphire caseback model so is the 1863 the movement reserved for the sapphire caseback ( 3572.50 and 3573.50 ) while the 1861 is the version for the metal casebacks? Additionally, according to the Omega site, the 3573.50 is rated at 50m while the strap version, 3873.50.31 at 30m. Is it a typo? ???for the heads up on the screensaver. Fun this. Cheers pal ZIN |

The solid back has a rate of 50 mtr and the display back 30 mtr. |

Ummmmnnn GJ, the 3573.50 is the display back. Perhaps it's newer hence the increased depth rating over the standard 3570.50. The Moonphase is also rated at 50m as is the Moon to Mars watch I believe. But why should the strap version of the 3573.50 be only rated 30m. I still think it is a typo. Cheers pal ZIN |

The 863 and the 1863 have the metal brake (vs. Delrin) and "Geneva waves" on the movement plus the extra jewel:  Fr. John+ |

Aha - I knew you'd know Fr John.  I thought it may have been the Delryn but hadn't thought of the Geneva Waves. I thought the extra jewel was on the 1861 as well - show you how little I know. I would have liked to say it was also a ploy to see a picture of your casebacks again. At the appropriate time after the Sapphire F&B settles in, one of my projects is to get an 861 and attempt a conversion but knowing me I'm more likely to call Swiss Time Services asking their cost for this little exercise. How is PW2 coming along? Many thanks again - I can now sleep easy tonight Best ZIN |

To clarify, both the 1861 and the 1863 have the extra jewel. The 863 has the 18th but the bridge still says "Seventeen".
Apparently Omega put "Eighteen" on all the rhodium bridges and included the 18th on the 1861 as well as the 1863.
My friend Jon (454gun on another forum) is blessed to own two 3572.50's but one has the 863 movement and the other has the 1863. Both have the 18th jewel but the 863 bridge says "Seventeen".
Some 3572.50 models have the 863 movement so the movement is not determinative of a 3592.50 or a 3572.50. The difference between the two is that the movement ring on the later model is taller eliminating the need for a spacer ring to hold the movement in place.
I refer to the 3572.50's with 863 movements as "transitional" resulting from Omega's practice of using up whatever is in the parts bin.
I wonder if we'll ever see a 3592.50 with an 1863 movement? I guess it's possible.

Why would they be persuaded to reintroduce the 3592.50 albeit with a 1863 Fr John? Just wondering... Best WIShes ZIN |

I was just speculating that if Omega can put an 863 into a 3572.50, they could just as well have put an 1863 in a 3592.50.
BTW, one other difference in the 3592.50 and the 3572.50 is the wording on the display back. (See my photos above.)
The 3592.50 reads "Apollo XI - Speedmaster - (blank) - First Watch - Worn On - The Moon" and in some instances, "(blank) - Speedmaster - Apollo XI - First Watch - Worn On - The Moon".
The 3572.50 reads "Omega - Speedmaster - Professional - First Watch - Worn On - The Moon".
And of course, the 3573.50 "sapphire sandwich" incorrectly reads "Omega - The First - And Only - Watch - Worn On - The Moon". We know for a fact that Omega was not the only watch worn on the moon.
