While the first TUDOR divers’ watch, reference 7922, dated from, it was several years before reference 7928 marked the first mention of a TUDOR Submariner in the brand’s general catalogue. Meanwhile, TUDOR was experimenting with a number of technical solutions to perfect its ideal divers’ tool. This absence of marketing documents did not however keep the first-generation models from being sold and immediately finding an appreciative audience, notably the naval military organisations of major countries.
Thus, while references 7922, 7923, 7924 and 7925 had the shared characteristics of not having crown guards and featuring 37 mm cases, each one offers specificities derived from, and representative of the research conducted by the brand. Reference 7922 was waterproof to a depth of 100 metres, the 7923 had a manually-wound movement, the 7924 was waterproof to a depth of 200 metres, and the 7925 possessed all the characteristics of the 7924 but was waterproof to a depth of 100 metres.
The last reference of the 7900 series, the 7928 included crown guards to protect its winding crown, ensured waterproofness to a depth of 200 metres, and was equipped with a self-winding movement. This list of characteristics was common to the Submariners that TUDOR would market until the end of the 1990s, making reference 7928 the sum of experience acquired over many years of experimentation in the field of divers’ watches.

OYSTER PRINCE SUBMARINER "BIG CROWN" 7924
Renamed “Big Crown” by collectors, an allusion to its 8 mm winding crown, reference 7924 appeared in 1958.

OYSTER PRINCE SUBMARINER "SQUARE CROWN GUARDS" 7928
In 1959, with the advent of reference 7928, TUDOR for the first time proposed the principle of guards to protect the winding crown from shocks.
