solar powered w rotating bezel / diver? duro or promaster titanium

I am looking for at watch with rotating bezel /simple design that is solar powered.

i really like the look of the cassio duro. but I do not like the fact that I have to change battery.

I have been looking at citizen promaster titanium. I like it, but I think it it is a bit to crowded. and I am a bit worried it will be too big for my wrist ( 16,5 cm/6,5 inch.)

for those who have this watch, how big a deal is the titanium? I am not particular drawn to the watch because of the titanium but paying for it non the less.

ideally I am looking for

• solar powered

• rotating bezel

• simple dial

• black dial

• bracelet

any recommendation or advice on size is much appreciated.
