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.
