In fact, the Citizen BN015X to BN016Y series are the same 44 mm dive watches with differences in color variations the smaller 37 mm versions for women and men with small wrists is the Citizen EO202X series all use the same E168 Eco-Drive caliber, and are of course ISO 6425 certified as true dive watches
The "Unite" model looks like the ideal resort watch - fun and bright, but will do the job in the pool and in the sea. I wonder how it would look on the torquoise strap? Nice too that all the text is applied, no doubt necessary because of the dial material, giving it even more 3D depth and interest. Have they done the same with the other models, or do they use printing?
