I'm looking for a new watch and right now I'm leaning towards a brown leather strap, white face, and silver casing in the $3000-$5000 range (or lower if there's anything you would recommend). Moreover, my wrist is fairly small so i'm looking for case sizes that are 38-40mm. For instance, I'm a fan of the IWC Portofino Chronograph IW391007 (http://www.iwc.com/en/collection/portofino/IW3910/) but i think the case might be too large. Any suggestions? Thanks.
