Over the years, Rolex has offered the Datejust and Rolex Day-Date with a range of bracelet styles. Each of the models comes with just one bracelet option. As I mentioned, the Rolex Day-Date II comes only with the Rolex President bracelet. This has three rounded links and is a more modern version of the famous jubilee bracelet. It fits very comfortably on the wrist and features a polished center link flanked by two brushed links. The Rolex Datejust II has the Oyster bracelet that is also three links with a polished center link. It is sportier looking than the Rolex President bracelet as the links are larger and flatter. Neither bracelet is per se better than the other, but aside from style, there are some very minor differences.
The Oyster style bracelet is a more simple version of the wonderful bracelet on the Rolex Submariner (reviewed here). It doesn’t have the Glidelock deployant and is styled a bit differently (the Submariner does not have a polished center link). The Oyster bracelet has a distinct looking deployant that is much more diminutive than on historic Rolex watches. The metal is all milled and nothing is stamped. The deployant closes with a reassuring click, and a soft tug on the end of the deployant is necessary to open the bracelet.
On the Rolex President bracelet, the system is almost identical, but it is designed to have a hidden deployant. The release mechanism is hidden under the bracelet and a tug of the Rolex crown logo releases the bracelet. Neither bracelet is better than the other overall. You get a more formal look and probably a bit more comfort with the Rolex President bracelet, while the Oyster bracelet is sportier looking.
