1- The first waterproof wristwatch "Oyster", 1923
2- The first wristwatch with an automatically changing date on the dial (Rolex Datejust ref.4467, 1945)
3- The first wristwatch with an automatically changing day and date on the dial (Rolex Day-Date)
4- The first wristwatch case waterproof to 100 m (330 ft) (Rolex Oyster Perpetual Submariner ref.6204, 1953)
5- The first wristwatch to show two time zones at once (Rolex GMT Master ref.6542 , 1954)
6- The first watchmaker to earn chronometer certification for a wristwatch
7- Unlike ANY other Rolex watches manufactured after 2001, the Milgauss GV does not sport any laser etched coronet in the crystal at six o' clock. It is said that this is due to the green edge that tends to glow up quite a bit in certain light condition, resulting in the laser etched coronet being too obvious if it had been etched on the crystal.
8- With so-called "Faraday" case
The Milgauss is the only current reference having a so-called "Faraday" case which consists of a "case inside the case", the inner case made of soft iron which leads magnetic influence away from the movement inside. It is the only current Rolex that is anti-magnetic to 1,000 Gauss.
9- Special movement was developed for Milgauss
A special movement was developed for the Milgauss, unique for the reference: The Rolex cal. 3131. It not only features the in-house Parachrom Bleu hairspring but also an escapement made out of a paramagnetic material.
10- With special bracelet
A special bracelet is made for the Milgauss watches, too: the bracelet ref. 72400. NO other Rolex watch uses this bracelet.
11-Unique Winding crown
The winding crown is unique to the Milgauss, as well. Although it is a Twin Lock crown, with its 7mm diametre it is larger than the standard Twin Lock crown.
In addition, The Milgauss comes in stainless steel only, but is not classified by Rolex as a "sports" Rolex. However, it does feature a case back inscription; a feature that has hitherto only been seen on sports Rolex watches.
