: I was just browsing the omega website today
: since I wanted to understand the speed
: master line better. While browsing through
: the various Speedy professionals, I noticed
: that some use an Omega 1861 movement and
: others use an Omega 1863 movement. Since I
: am not very familiar with the speedy line, I
: have the following questions:

1. What is the difference between the two movements?

1863 is the Display Back version of the 1861. It has more decoration, and it replaces a nylon part with a metal part, strictly for looks.

: 2. which one is superior or are they both equally competent?

Both are equally competent, though the nylon part (Chronograph Brake) is a better material for its job (but not as good looking), so I'd give the edge to Caliber 1861.

: 3. which one was used in the moon watch and
: which of the speedys qualify as moon watches
: (display case back with moon watch engraving
: et al)?

Caliber 1861 qualifies for EVAs, but was never on the moon. It is the Grandson of Caliber 321, which was on the moon, and son of Caliber 861, which was most likely on the moon. Both movements were tested and certified by the NASA. Caliber 1861 adds 1 jewel, and has a different finish, but is still essentially caliber 861.

: 4. why does the broad arrow use a 3303 movement
: and is it better than the 1861/1863?

Caliber 3303 is a completely different animal than Caliber 1861/1863. It's Automatic, a Certified Chronometer, has a Free Sprung Balance and Column Wheel Chronograph mechanism (as did the Cal 321). IMHO, it's a better movement, but I'm sure others will argue with me about it. Cal 33xx is a F. Piquet movement, while Cal 186x is a Lemania movement. Cal 186x is a 50 year old design, Cal 33xx is a 4 or 5 year old design.

: 5. Which one (broad arrow or pro) is more
: collectible?

Both are still in continuous production, so I don't believe either is more "collectable" than the other. A Cal 321 is pretty collectable though"

: any insights would be highly appreciated.
: Thanks

Cal 33xx had some teething pains out of the box. Hopefully these bugs have been worked out. I've had both Caliber 3313 and 1863, and both failed on me at one point, and was sent off to Switzerland for Warranty Overhaul. I still have Cal 3313, and sold Cal 1863
