Features and Functionality of Rolex Submariner and Datejust

Because the Rolex Submariner and Rolex Datejust are each designed for different purposes, there are some key differences in the design, features, and functionality of these two watches.
First, the Submariner is significantly more water-resistant than the Datejust – a distinct requirement since Rolex is specifically designed for diving. The current production Datejust is officially water-resistant to 100 meters (330 feet), which is more than adequate for any water environment you may encounter in your daily life. However, the official depth rating of the Submariner is three times that of the replica Rolex Datejust, providing users with a water resistance of 300 meters (1,000 feet). 
In addition, while all Rolex Datejust watches feature a date window at 3 o’clock on the dial, the Rolex Submariner comes in both a date display and a non-date format. A dial that only shows the time makes the display more legible, and the earliest Submariner watches were originally produced in a dateless format.
In addition, the bezels fitted to the Rolex Submariner and the Rolex Datejust are quite different – both in design and function. The Datejust’s bezel is entirely decorative, except for its use in securing the crystal to the case. Thus, the bezel of the Datejust is fixed, and it comes in several different styles offering different aesthetics. Meanwhile, the bezel of the modern Submariner is a unidirectional rotating chronograph bezel with Cerachrom (ceramic) insert and engraved 60-minute scale. This bezel allows the fake Rolex Submariner to act as a primary chronograph for events up to one hour long – perfect for posting subsea time or decompression stops while driving.
Finally, while both the Rolex Submariner and Datejust feature a bracelet clasp with a built-in extension system, the clasp on the Submariner has more room for adjustment than the clasp on the Datejust. The Datejust’s Easylink extension system allows the bracelet to be quickly expanded or contracted without the use of any tools by 5 mm. The Glidelock extension on the Submariner is also tool-free to adjust, but it allows the bracelet to be adjusted in 2 mm increments for a total length of up to 20 mm.
The key reason behind the different clasp extension systems also stems from the different uses of the two watches. While the bracelet on the Rolex Datejust only needs to be adjusted to compensate for the expansion or contraction of the wrist during the day, the bracelet on the Submariner needs to be able to expand to fit the sleeves of a thick wetsuit.
