This year marks the 40th anniversary of the Rolex Explorer II so its only right that the company celebrate the occasion with a brand new version. The new Explorer II gets a larger 42mm case and features the company's new 3187 calibre that boasts Paraflex shock absorbers and a non-magnetic Parachrom hairspring. They've also captured the look of the 1971 original with an orange 24-hour arrow hand. Link
