Tudor Submariner Reference 7928
The Tudor Reference 7928 is perhaps one of the most classic Tudor sports models. It saw a long production run fromapproximatly 1959 (earliest caseback we have seen is an IV.59 with a 300.xxx serial) till circa 1968. There are several versions of the 7928.
In broad overview there are two reference groups. The 7928 and the 7928/0. The /0 was added to many Tudor references in the mid 60′s to denote stainless steel – in a similar fashion as Rolex did with their models. Within the two main groups, a large amount of variations exist. Many of those are pictured in this section.
It is quite complex to chart all the dial variations of the 7928. First of all, these watches due to their lower price point (and also several versions used for military use) have had questionable service histories. This means that dials may have been changed back and forth, redone, relumed, repainted or even faked. In this section we will do our best to describe the known varieties.
The early 7928′s feature the “chapter dial” where a inner ring is printed on the dial a few milimeters from the edge.
The upper half of the dial features the classic small Tudor Rose. Underneath the text ” Oyster-Prince “. The bottom portion differs a bit from model to model – but typically they feature the ” 200m = 660ft ” (denoting depth rating of course), then ” SUBMARINER ” and the two last lines ” Rotor ” and ” Self-winding ” – which of course denoted the automatic movement.
The following dial variations have been found so far: (I am certain there are a few more at least)
MK I. Always cased in a Square Crown case. Gilt writing. Gilt track.
MK II. Gilt track – silver writing
MK III. Silver writing and no track
MK IV. Regular writing and markers similar to Rolex 5513
MKI dials are also seen in exclamation point (small trit dot at 6) and Underline dial variations.
At least 4 case variations have been seen. The early “Square” (quite unique) crownguards (chapter dial). One variation of pointed crown guards (1962-63, chapter dial) and minimum two variations of the round crown guards.
The crystal for these cases are all Tropic 19. This is shared with (amongst others) the Rolex 5512 and 5513 Submariners. Case and look wise – these are the ones closest to the Tudor Reference 7928. It is fair to say that the 7928 was the “poor mans” version of the 5513. (i.e. not chronometer certified). Now prices are usually up to 75% of their Rolex counterparts in similar condition.
