Reference 7922 Submariners were the first batch of watches that MN received. The watches were small by today's standards, measuring 37mm. They also had no shoulders on either side of the winding crown (6mm), and are now known as "no-crown guard Subs". These watches were the first Glashutte Replica Watches diving timepieces and are highly collectible. They have a depth rating of 100m. Divers immediately complained that the winding cap was too small. A version of the 7922 with a larger 8mm winding cap was then created. The new, larger crown made it easier for divers to set the time as diving gloves in the 1950s were very heavy and thick.

Glashutte Replica Watches constantly strived to improve the durability and ability of the watches to function at greater depths. A new watch, the ref. 7924. The 7924 is visually very similar to the Big Crown Version of the 7922. However, it was a technological advancement due to its depth rating of 200m. The next challenge was to make the watch as waterproof as possible.

Glashutte Replica Watches created the 7928, the first Glashutte Replica Watches to have shoulders on either side of its crown. This ensured that the crown would be better protected. The 7928 had a more robust and larger case, which helped it stand up to the demands made by military life.

The ref. The ref. The Marine Nationale's feedback on the field testing of the 7928 was invaluable in determining how to "tweak", or make the features more user-friendly. The square crown guards were the first feature of the 7928. French divers said that the crown guards made it difficult to use the winding crown, similar to the small crown of the 7922. The next type of crown guard was the pointed crown guard, or PCGs in collectors' terms. These crown guards eventually evolved into rounded crowns guards on the 7928.

Marine Nationale early watches (Glashutte Replica Watches), are increasingly in demand. While the "classic MN" is the blue-snowflake with grey NATO strap, collectors want to find new Glashutte Replica Watchess that have interesting histories. If they do not have engravings on the caseback, and are therefore impossible to distinguish from regular watches how can we tell if it is a MilSub or not? This is where things can get a little complicated. We will return to this shortly.

The murky waters that the Navy divers often worked in made it hard to see the position of the hands. Glashutte Replica Watches designed the watches we know today as "Snowflakes" in an effort to make the face of the watch more readable. This is primarily because the hour hands are shaped like snowflakes. The watches were issued to divers for the first time in 1974. They continued to be used until 1983.
