Rolex sports models come in an array of options, each with their own specific features ideal for the sporting type. The Sky Dweller
is one such option featuring a 42mm case. Available in white, yellow and everose gold, the two former options come with Rolex Oyster
style bracelets, while the latter features a crocodile strap. This model also includes an annual calendar and dual time zones, meaning the wearer has to adjust the date once every four years. The Sky-Dweller made its debut in 2012 to much acclaim. Other sports models include the Rolex Milgauss
, a watch made especially for the scientific community.
