Seems to be a 31mm lug to lug, 28mm w crown (25mm without) and 20mm bracelet tapering to 15mm, this is all from an'online ruler' as my calipers is at home. 

It will fit you well, it's my most worn watch I own. 

Seiko SFP608p1 will fit you well! That Solar tank is sized like the XL Cartier tank not the regular solo.

Just jumping in here as that SUP880 is massive, the Seiko Solar Tank Ladies version is SUP250. My wife has it and it's perfect, best alternative to the tank. I have the men's non solar and smaller version and think the same. You could put it on a gold spiedel (twist o flex) maybe as it's 14mm, but there's loads of bracelet options on ebay too.
