I ordered this watch over the SSC009 because the SSC007 (this watch) claims to have a screw down crown.  It does NOT have this.  The description of the SSC009 didn't say anything about a screw down crown so I figured either they both have it or neither.  Turns out neither have it.  Not a huge deal, but I'm around water a lot and swim, apt to snorkel, and shower with my watches on so want them to be fairly waterproof.  I've a couple dive watches that are also 100m rated (330') and have never had a problem with leakage, but they also have screw down crowns.

The other thing I didn't like was the red color for the labels on the outside dial (e.g., Fuel Lbs, Oil Lbs, etc.)  I'm 49 and vision is what it is (I wear glasses) but I found it very difficult to read the red.

I ended up returning this watch and getting the SSC009 (same watch but with white labels and white sweep hand with red tip).  Doesn't have the screw down crown but I find it much easier to read than this watch.

While I'm thinking of it, the alarm is not very loud at all and only lasts for 20 seconds.  Not sure why they did that and didn't let the alarm beep for a minute or until it is turned off.  Louder alarm would be nice as I can't really rely on this to wake me.

The alarm function is relatively easy to set and it works great.  The watch itself is a looker and on the larger side.  The band is VERY nice and very similar to an Omega Speedmaster.

Great watch but no screw down crown, difficult to read labels, and soft alarm took it down a couple stars.  I'd say 3-4 stars.  Nothing wrong with the watch at all though!

I'll review the SSC009 as well.
