Released in 2023, the Sky-Dweller 336238 is also presented with a 42mm Yellow Gold case and black rubber strap. Like the previous model, it features a black dial with both a second time zone and an annual calendar. 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 Saros mechanism, which changes instantaneously (an annual calendar automatically differentiates between months of 30 days and 31 days, need be adjusted just once per year, at the end of February) is relatively simple. The Rolex Sky-Dweller calendar has an unusual month display. The hour numerals correspond to the 12 months of the year. Next to each numeral is a window. To set the watch, you use both the bezel and the crown. First you rotate the bezel to one of three positions to select which of three functions — date, local time or home (24-hour) time – you want to set. Then, using the crown, you set the function, going either forward or backward. Sky-dweller 336238 is also resistant to 100meters/330 feet but it has an updated calibre movement 9002 with 72-hour power reserve.
