Mitch and all
The bevelled edges make the revised CAD version look too "ergonomic" in my (very humble) opinion and not enough "tool".
So - I would like to say:
1. old caseback preferred;
2. new 5 minute markers, bezel and dial colour are superb;and
3. red HEV is not a priority to me but, form relying on function, should be grooved so that it can perform its intended function. The LM-7 HEV is an "unscrew thread to release pressure" arangement, not a push-button - am I right?
We are not all experts (I am certainly not) and it is great to be able to express what is only an opinion after all.
Another pat on the back from me for all the patience you show, and the great work you do, Mitch. Well done!
