Below is a list of everything that's new in the new Rolex Explorer:
39 millimeters rather than 36. That's only one millimeter smaller than their other tool my gifts jewelry (like the new Rolex Submariner Date).
The movement now uses the new Parachrom Blue hairspring which we discusse previously in the context of the Rolex Milgauss.
The now-standard signed chapter ring not my favorite new feature, but believe me, I wouldn't let it stop me from wearing one.
Slightly redesigned dial: the word "EXPLORER" has been moved from the top where it used to be down to the bottom.
Features that haven't changed:
COCS certified.
Solid steel case and bracelet.
Sapphire crystal.
Screwdown crown.
Water-resistant to 100 meters or 330 feet.
No date (part of what it makes it so simple and beautiful).
Rolex's second announcement this year at BaselWorld 2010 was a redesigned Explorer. I've always loved the Explorer for its unparalleled simplicity and stark elegance, but at only 36 millimeters, it was a tad bit diminutive by today's standards. Not anymore. The size of the new Explorer is much more in line with modern expectations.
