Aqualand/Promaster
I use a Citizen Promaster and I don't know how it compares to the Aqualand, but these are my thoughts of using the Citizen for freediving:
It is definitely made for scuba and not freediving. For instance it has a rapid ascent alarm which can not be turned of, which can be annoying.
The good part is that the alarm (including the depth alarm) is loud and easy to hear. This seems to be the biggest flaw of the D3.
It only has memory for four dives (plenty for scuba, but not for freediving) and you have to "reset" it every time you surface or it will consider your next dive a continuation of your last one.
It does not have a surface timer like the D3 does.
It does not have a computer interface or per second memory for dives like the D3 has.
Made from steel (and being very heavy for a watch) it looks like it could withstand about ten times as much abuse as the plastic D3.
All things considered, if I had to get a new watch, I would prefer a D3 over another Citizen unless I got the Citizen much cheaper (say half the cost of the D3). Keep in mind that I have never seen an Aqualand, I am comparing with a Promaster!
