The Rolex Day Date is the only wristwatch from the Swiss brand offered exclusively in gold or platinum. This makes it the most exclusive timepiece of Rolex. The Day-Date is modestly sized by contemporary standards and remained 36mm until 2008 when the brand added a 41mm model to its lineup. But, in 2016, this was replaced with the Day-Date 40mm.
The 40mm model was warmly received as it is proportioned exactly like the original 36mm. But, the 40mm was not only an improvement to the prior models. Indeed, it comes with a newly developed movement that has 14 patents, making it the most sophisticated movement that the brand offers.
