Hello gents, landed a decent Scubapro 500 recently on the bay. Thoroughly enjoying the watch, but can't find much history on it. Can anyone help? So far the best I can find is here, but there isn't much data: http://thewatchspotblog.com/?tag=scubapro http://forum.tz-uk.com/showthread.php?294746-ScubaPro-500-History-amp-production-numbers. Based on my searches, I'm guessing that production numbers probably weren't far about the 5K mark, based on serial #s of the watches on sale. Mine is in the high 3Ks. Also, anyone know where I can find a replacement crystal? Cheers.
