Speedmaster Broad Arrow early 2000's, opinions ?

These are IMO an upmarket version of the Moonwatch in exactly the same form factor (and a similar 178.0022 case number note). The later 9300 models are much bigger in comparison and are really a very different offering. There are no actual Moon connections since they don't use a Lemania derived movement, in fact it is rather more aristocratic that that as it is based on the F Piguet 1185. Many Omega collectors overlook them but do so to their disadvantage in my opinion, a healthy Broad Arrow is an excellent watch and this movement is in a family that has been used by AP, VC, Panerai, Blancpain, Breguet etc, with Omega being the lowest tier manufacturer to actually implement it!

There have been issues with the Omega development of this movement, particularly with the very first but these have been ironed out and a watch that has been back to Omega at least once should be fully reliable as the movements have received rolling updates which have ironed out the problems. Chuck Maddox was scathing about these when they were first released yet lauded the Grail which used something that is from the watch equivalent of the farmyard and I think he plain got it wrong.

Mine is the slightly later 3313 co-axial version, shown below. I am wearing this today in fact. The earlier 3303 movement model you refer to has a white or cream dial, this one has varying silver finishes so changes in look as the light catches it.

The F. Piguet based movement was much maligned, mostly by one person who made it his life's work (it seemed) to go into every thread on this movement in every forum and trash it. Yes, the chronograph had some possible issues, but in all of then that I've serviced over the years (in both Speedmasters and Seamaster chronographs), I've only ever seen one that was actually affected by one of the issues. Omega has upgraded all the chronograph parts that were problematic, so if you get a watch that was serviced after around 2008, all of the upgraded parts would have been installed as part of a normal service. Once that's done, the movement is fine.

For the co-axial version, this is the only movement that Omega made the decision to upgrade from the 2 level co-axial escapement, to the 3 level escapement. This resolves the inherent design flaw in the 2 level design, so it will be as reliable as any other 3 level co-axial escapement watch.

The version you mention in your first post, the 35512000, has the ivory dial, no 1957 text, and uses the 3303, which is not a co-axial version of the movement.

The other is ref. 32110425002001, which has a white dial, the 1957 text, and uses the 3313.
