I've noticed that on the new Chronomat Evolution (on the right) that there is no tubing visible where the threads supposed to be there to screw down the crown, yet it has the screw down function built internally.

Compare that to the previous Chronomat model (on the left) where you can actually see the threads on the tubing so that the screw down action takes place when it meets the crown.

I could only assume that the Evo has the better pressure seal due to its improved water resistance up to 1000 ft. as claimed, compared to the previous Chronomat at only 330 ft. But again if we compare the Rolex Sub, it still uses the old version of the screw down crown pressurised to 1000 ft. Comments?

Its not the screw-down crown that gives the added water resistance I don't think, it's the addition of the screw locked chronograph pushers as you will notice that typically it is the chronograph models that have lower water resistance... except the Chrono Avenger M1, which has Magnetic pushers. The Chrono SuperOcean does have 500m WR though, which is interesting.
