I'm a bit of a watch junky, like to change my watches daily, and recently decided to upgrade my collection after reading numerous reviews.  I purchased this watch along with a Citizen Eco-drive BJ6475-00E and a Casio MDV106-1A, both of which I liked very much and am also reviewing.  I'm 50+, don't dive and prefer an easier to read dial.  I immediately noticed the smaller bezel and crystal size between this listed 48mm watch, the 44mm Casio, and my other watches.  I wish I had taken a photo, but I was so disappointed that I sent it back immediately.  While you can still easily read the dial, due to the smaller size compared to others, it's just too "busy" for me.

You can go to the Citizen website, compare it to the other Promaster line watch photos, and easily see the difference between this one and the others listed at the 48mm case size.  Ironically, last year they came out with the BN0190-07E model, which is 44.5mm, and a dead ringer for the currently listed here $43 Casio, which came out in 2013.  Need I say more?
