It seems that you aren't a collector with a lot of Rolex watches.

Go to Google, "pictures", and type 16622. Yo'll find quite a lot of bad and good ones.

I advise you to take this Rolesium, because it's a multipurpose watch, i.e. a dress watch as well as a sports watch. The 16600 is often seen as dresswatch, but it's a little bit for fans, not for common public.

The 16622 has the "new type" bracelet with full links only.

The bezel of the 16622 is delicate, but it looks well even with small scratches. The watch has a superb dial I've never seen before and it's very elegant.

If you're wearing that watch everytime, think about buying it from an official Rolex dealer. With a discount of 5-15% only (US: 15-25), but fully guaranteed.

If it's for collecting purposes, it does less matter.

I'm owner of both watches, but for me they're part of my Rolex-collection. And of course both are reliable watches.

The 16600 is thick, and it's watertightness is over-the-top for normal use.
