Richard Mille joins the thin watch craze in 2011 with their 6.30mm thick “Extra Flat Automatic” RM 033 watch. For the complexity of a Richard Mille watch case 6.30mm thick is pretty darn good. The brand makes sure to maintain as much of the signature look as possible in the design of the case – and they also made it round. The hour numeral style is not new, but taken from the Richard Mille RM 017 Tourbillon (that actually was finally released this year).
