WatchProfessor’s take- despite the 42mm case size and full ceramic bracelet; the watch doesn’t feel as hefty as it looks.  It wears well on my very standard wrist (6.5in).  With the ROOS 30th anniversary, the inspiration of this came directly from the original Emmanuel Gueit design; it’s simply timeless; loving the modernity of the material while paying homage to the origin
