There are two sizes currently being produced for the Rolex Datejust line – the traditional 36mm and the Datejust 41, with a 41mm case. The Datejust II precedes the Datejust 41 and was produced from 2009 until 2016, so there are many of them available in the pre-owned market today.
The Datejust II and the Datejust 41 have the same 41mm case size, but the Datejust 41 has a more refined look. Here are the features that set it apart from other Datejust watches:
Larger case, slim profile - Despite being 41mm in size, the Oyster case sits comfortably on the wrist, with its slim profile and thinner lugs.
Design variety - It was initially available only in Rolesor steel and yellow gold, but that changed in 2018. It now comes in other two-tone designs, combining Oystersteel and yellow, white or Everose gold; plus an all-Oystersteel model.
There is a choice between a domed and fluted bezel, luminous baton markers and diamond indexes, as well as different dials – silver, black, rhodium, blue, sundust, and mother of pearl.
Bracelet - The Datejust 41 also offers both the sporty Oyster bracelet and the dressier Jubilee bracelet. Its Oysterclasp folding clasp is already equipped with the Easylink extension system which extends the bracelet by as much as 5 mm.
Calibre 3235 - It’s also equipped with Rolex’s Calibre 3235, their newest generation time and date automatic mechanical movement. This is equipped with the new Chronergy escapement (a patented Rolex innovation) which provides a power reserve of approximately 70 hours.
