What are the suggestions for a bracelet for my new Autavia Diver 100?

Right now, it is on an original corfam strap used on the Monacos (22mmm fits nicely, even though the lugs are 21mm). I am happy with the look and feel, but am also interested in alternatives. Do you guys suggest:

• the original bracelet (shown below), and if so any ideas where I might be able to find one?
• some other Heuer bracelet . . . but what is there in 21mm? or do I find a 22mm and shave the ends? What Heuer bracelet would look right on this Diver 100 . . . Monaco seems too flat . . . Maybe from a Silverstone?
• some other leather strap
• dare I even say it, a thick plastic divers strap?
