As some here have noted, this model comes with standard Titanium which scratches very easily.

If you look at it's twin model CA0021-53E  you will find the same exact watch, except it is made with "Super Titanium" which is 5 times more durable then stainless steel.

Google that model number (CA0021-53E) and you will find many online Ebay and other locations selling it, I got mine for only $239 delivered.
