audemars piguet royal oak watches the Triplock crown system

Triplock crown. The new GMT Master IIs use audemars piguet royal oak watches the Triplock crown system of the Submariner, Sea-Dweller, and Yacht-Masters. The crown is larger, heavier, easier to grasp, and in theory should make the watch more water resistant, though I don't believe Rolex has changed the depth rating. Green 24-hour hand. The 24-hour hand on the older GMT Master IIs is read. Rolex seems to have taken an interest in green lately as evidenced by the new green 24-hour hand, green bezel of the anniversary Submariner, and the green crystal of the new Milgauss (article coming soon). Inner bezel engraving. The inner bezel of the new GMT Master IIs are engraved with the word ROLEX all the way around. Polished inner-links. The links in the center of the Oyster bracelet are polished rather than brushed. Slightly taller case. The case audemars piguet royal oak watches on the new GMT Master II is slightly taller to accommodate the new movement.

The movement. The movement has been updated to the new calibre 3186. The 3186 doesn't have any new features, but apparently the movement of the hour hand is much smoother and more precise when setting the hour hand than it was with the 3185. Additionally, the main spring has been replaced with one which is more temperature resistant, which makes the watch more precise. (Read more about the new movement in this post by Henk Hoving.) New dial design. The new GMT Master II is outfitted with what has become known as the "maxi-dial" which means that the hour markers are larger, and both the the minute hand and the hour hands are slightly wider. The bezel. The bezel on the new GMT Master is ceramic rather than painted aluminum. This type of ceramic is extremely audemars piguet royal oak watches durable and resistant to abrasions and discoloration.
