The asthetic value of this time piece is off the radar charts. "Eye catching" and "attention demanding" would be putting it mildly. Functionality; however, is an issue in one regard. The screw down crown was engineered in such a way that it makes it a chore to manipulate. It's difficult, at best, to get the crown out to position 2. Love this Sub IV nonetheless. Just an awesome presence on the wrist.
