If its strap choices, I would suggest a black or grey nubuck strap in either buffalo, or maybe even crocodile. Do you remember the Jules Verne type of straps Panerai makes? I think those would look really cool when paired to your ceramic Bathyscaphe. Oliver, one of our moderators, also swears by the Barenia leather straps made by Blancpain. You could check them out as well.
