The SH21 is a wonderful piece of engineering, but as used (so far) in the C60 you only get the 5 day PR and COSC for the very expensive uplift over a Sellita. These two remainder plain Janes really don't cut it compared with recent C60 mk2 colour schemes either, nothing special at all compared with recent LEs.
OTOH I am very happy with my C8PR where the SH21 permitted CW to create a unique watch at a phenomenal price point.
For anybody interested, why not make CW a lowball offer? After all these two have been in the unsold box for a long while now.
