The extremely useful annual calendars of the Fake Rolex Sky-Dweller and Omega Constellation Globemaster Annual Calendar not only have an official chronometer certificate, but are also certified according to strict criteria of their own. The technical details of the calendar watches are interesting.
Two wristwatches with annual calendars – a comparison
The comparison of these current wristwatches with annual calendars from Omega and Rolex is exciting. After all, the Rolex Sky-Dweller and the Omega Constellation Globemaster Annual Calendar are very similar. Both have a waterproof stainless steel case, a grooved bezel and a double-certified automatic movement with an annual calendar.
Date displays and calendars have been known in connection with mechanical watches for centuries. The simplest of them have a maximum display accuracy of 92 days. From July 1st to September 30th of a year. Then they indicate the 31st, even though October 1st has already arrived. If you don’t want to correct it manually, you can strap a perpetual calendar to your wrist.
This recognizes and takes into account the different month lengths in normal and leap years. The calendar eternity will not end until the end of February 2100. According to the Gregorian calendar adopted in 1582, the leap day must be omitted in all secular years that are not divisible by 400. In this sense, 2200 and 2300 will not have a February 29th. The annual calendar, first offered by Patek Philippe in 1996, can be considered the little brother of the perpetual calendar.
In this case, you only have to do it at the end of February. After that, the owners have a year of peace. Omega offers two such wristwatches with an annual calendar: the Constellation Globemaster Co-Axial Master Chronometer Annual Calendar 41 mm. Rolex, on the other hand, offers its annual calendar as an Oyster Perpetual Sky-Dweller with a diameter of 42 millimeters.
Since 2024: the Rolex “Sky-Dweller”
Because of its longer biography, we start with the multifunctional travel wristwatch. In addition to the caliber 4130 with chronograph and the 4161 based on it in the “Yacht-Master II”, the 9001 built into it with a classic anchor escapement, four hertz balance frequency, a barrel and 72 hours of autonomy is one of the most watchmaking-wise complicated things that Rolex offers its customers. The first of a total of 14 patents for the movement, its sub-dial mechanism and the control of the functions dates back to 2004. Eight years then passed before the launch of the associated “Sky-Dweller”. As is well known, good things take a long time at Rolex.
