I was glad there was a user manual included!
It's a bit of a complex watch to set up, but overall I managed to set it up in a matter of 10-15 minutes. It's a very nice watch for under a suit, and probably the most expensive watch I've ever owned!

Not only does it look like more expensive watches, it also has great feats, like it has a alarm, 24hr display, calendar (weekday, date, and crossover year (not real year display)).
It also has a local and a secondary time (for eg: travel).
Everything is analog.
And what I like most, is that it automatically adjusts April 29th every 4 years!

The back plate is black, rather than blue (like you see on some vids, or photo's), and just like the watches name (ECO-Drive) (meaning economic on battery consumption), this watch is probably a perfect balance of performance, and economy ($$$).

I bought it because of looks, but also because of it's self charging feat (the battery gets charged via solar power).
Just wearing it outside or in the office, is enough light to keep it charged. Battery supposedly holds charge for more than 6 months, after which it is recommended to charge the watch by bringing it in the light, and should not be replaced over the lifetime of the watch.
They recommend to wear the watch at least 1 day in the month, outside, for charging purposes, or a few days a month in the office.
The watch also seems to have complex energy saving feats, like making the second pointer point every 2 seconds instead of 1, or stopping the second indicator entirely, to save energy.

I had to remove 2 chains for it to fit me, but it was easy to do myself.

The 2 cons I find, is that the gold is overlayed (plated), so not solid gold bracelet-links, and the glass gets dirty easily with finger grease.

I bought it on cyber monday, $20 more expensive than a week later, which is a pitty.
It's my most expensive watch yet, but I like it!
