In the past half-century, since it launched its GMT-Master, rolex replica watches has brought out just two new complications: the rolex replica watches Yacht-Master II, in 2007, with a countdown yacht timer, and the rolex replica watches Sky-Dweller, equipped with both a second time zone and an annual calendar, in 2012. In this feature from our Baselworld 2012 issue, we explain how the Sky-Dweller, and its innovative movement, work.
The rolex replica watches Sky-Dweller contains a new caliber, 9001, which rolex replica watches makes in house. The second time zone is indicated by an off-center, rotating 24-hour disk. Local time, indicated by the center- mounted hands, can be adjusted quickly when you change time zones by setting the hour hand forward or backward in one-hour increments. The minutes, seconds, and second-time-zone indicators are not affected during this operation.
The calendar mechanism, which changes instantaneously (an annual calendar automatically differentiates between months of 30 days and 31 days, and need be adjusted just once per year, at the end of February) is relatively simple, rolex replica watches says: the company has added just two gear ratios and four gear wheels to its existing instantaneous date calendar. As rolex replica watches explains it, “The mechanism is designed around a fixed planetary gear wheel at the center of the movement. A satellite wheel engages with the planetary wheel and rotates, orbiting the planetary wheel in one month, driven by the date disk. The satellite wheel is fitted with four fingers for the four 30-day months (April, June, September and November). Click on watch photos for larger images.
