The three watches you mention are very different in function and style.
Maybe if you give us some more info on what you would like to get out of a watch we might be able to point in some directions…
The Master Compressor Chronograph 2 is a more traditional chronograph while the the AMVOX II has the very unique crystal pushers.
The only one of these three you mention that I personally have any experience of is the NS Alarm – a great watch!
If it’s a big, tough and sporty diver’s watch you are after you can’t go wrong with this one!
The alarm function is a very usable complication, IMO.
I think first you have to decide what kind of watch you are looking before anybody can give you any good advice.

since these are VERY different pieces.
My personal favorite, by far, is the NS Alarm. I love the ceramic, bead-blasted bezel, the 300-meter water test and the alarm - which sounds superior emanating from a titanium case. Oh, and the articulated rubber is AWESOME. Plus, you get the JLC adjustable clasp.
So, decide the functional use you want (dress, casual, sport, etc.), and then draw columns with + or - to decide.

I have currently a Rolex deepsea, New 18K yellow gold submariner, Breitling Navitimer World, Omega Speedmaster Co-Axial, Audemars Piguet Royal Oak Offshore (Panda) and a Tag Heuer Link.
Tried all of the above watches again and they all have there pros and cons...
Although I'm more leaning towards the Navy Seals Alarm and the new Chrono II... the one very sporty, the other for more formal times (the problem is that I never wear suits or black tie, but then again I already have so many sporty watches pfffff difficult to choose (and I cant afford to buy both...)
...there are a few of us, at least, who have had trouble deciding among the JLC sports watches. I, too, went through a similar "this or that" dilemma when choosing among a JLC alarm, the Extreme World Chrono, a JLC diver and an AMVOX2. What I ended up with is inconsequential, but suffiice it to say I had to get and OWN each of these to figure this out for myself. I wish you a speedier and more efficient decision process than mine. LOL.
As all have already advised you need to figure out which functions (alarm, chrono, diving capability) is most interesting and useful to you; but more importantly try each one on let yourself hear which one sings to you the loudest. Which one keeps you up at night?
That said, if it were me choosing among the three you are considering -- I would go for the AMVOX2. It is original, unique among chronographs, looks awesome -- well, it is simply more interesting to me than the other two. But you can't go wrong with any of them. It is a very hard choice you have set for yourself, but an enjoyable one.
Good luck,
