I've never cared about downloading dive history to a computer. All I do is freedive, and I'd just be embarrassed having a record of my short breath holds.
So if all I want to is charge the watch, will this thing do it in spite of the fact that I can't connect to my Mac?
Hi Bill,
Been away for a while, but I'd like to address your questions.
Yes, the Amazon listing you linked to is the Cyber Aqualand NX. As far as I know, it was discontinued from production recently. There was also a lower-cost model called the Cyber Aqualand that doesn't do nitrox calculations. It was discontinued several years ago.
Since you aren't interested in computer analysis, you can just use the watch with its charging unit, and don't need the optional charging/communications unit used to hook the watch up to your computer.
Even though Amazon can't supply it, since it is discontinued, there are lots of stores still selling stocked units, and people sell them used sometimes too. You almost always can find a few for sale on eBay, for example:
[ame=http://cgi.ebay.com/CITIZEN-PROMASTER-Cyber-Aqualand-Nx-PMC67-2051-/390171445244?pt=Wristwatches&hash=item5ad807c7fc]CITIZEN PROMASTER Cyber Aqualand Nx PMC67-2051 - eBay (item 390171445244 end time Dec-12-10 18:18:20 PST)[/ame]
Note that this listing includes the charging/communications docking unit. You could look for a lower priced listin with just the charger Watch out, though, for people who try to sell the watch without the charger.
The watch charges whenever it is in the charging or charging/docking unit, irrespective of whether the charging unit is connected to a computer or not.
A really neat feature of this watch is that its charger runs on 4 AA batteries, not AC power, which means you can charge the watch up even when you are in a location with no AC, such as a boat or campsite.
The watch is beautiful, one of the nicest digital watches I've ever seen, and every review I've looked at has been positive.
If you're really interested in this watch, you could download its instruction manual from this address:

and go through it step-by-step, visualizing how you would use the features when diving.
