Steve - Watchbandcenter have them in stock. You might like to check out the Morellato Cordura too. Just got one out of curiosity and very impressed. Not as thick as the Di-Modell (and not as expensive) but as it's Cordura it's completely waterproof (and sweatproof!) with a Lorica (artificial leather) lining and hard wearing to boot. You'll wear out the watch before the strap...
