This is a 42mm watch, not a 48mm watch!

It is quite strange, because even the citizen website on this model confirms a 48mm dial. However, it is defintely a 42mm dial.
42mm dial is how it is sold at Macys as well as jomashop. I took out the digital calipers to confirm after it looked small, and lo and behold it is a 42mm watch.

So if you're looking to buy a nice 48mm divers watch, this is not for you.

case diameter typically doesn't include the crown. case size and case diameter are classically a measurement from 9-3 not including the crown.

if you check the listing, you'll notice it states the following in specs:
* 48 mm stainless steel case with mineral dial window
* Case Size: 48mm

as well as stating:
* Case diameter 43 millimeters

So in the very least, it is inconsistent. The product specs clearly state more often that it is 48mm.
