Tudor Submariner Ref. 7928

Partially verified

The Tudor Submariner, reference 7928, is a self-winding wristwatch with a distinctive case design known as 'pointed crown guards' (PCG). Dating to circa 1961, the watch features a glossy black dial that has undergone a transformation, resulting in a brown 'tropical' patina. The dial is marked with gilt text and luminous hour markers that show signs of age. The stainless steel case retains original factory chamfers. It is fitted with a knurled rotating bezel and a black 'fat font' insert, complete with a patinated pip. The timepiece is presented on a later-era 'stretch-rivet' Oyster bracelet secured with a blade clasp. The handset matches the patina of the dial indices. This watch represents an iteration of the early Tudor diver's watch line, characterized by its specific case architecture and the aging process of its original dial surface.

Object description

Case and Bezel

The watch is housed in a stainless steel case featuring the 'pointed crown guards' configuration. The exterior geometry includes visible factory chamfers along the lug edges, which the auction description reports as remaining thick and symmetrical. The case is integrated with a rotating bezel characterized by a knurled edge, providing a textured surface for manual adjustment.

The bezel is fitted with a black 'fat font' insert, which contains a circular luminous pip at the 12 o'clock position. The insert shows signs of use while retaining its characteristic typography. The case architecture suggests the design period of early 1960s Submariner models, specifically the reference 7928 designated by the manufacturer.

Evidence for this section
  • “The case remains thick and symmetrical, with the 'pointed crown guards' clearly on display and factory chamfers visible.”
  • “The knurled bezel houses an excellent black 'fat font' insert with a patinated pip”

Dial and Hands

The dial is described as a glossy black 'gilt' surface that has aged over time. This aging process has shifted the original black finish to various shades of brown, a condition referenced as a 'tropical' patina. The text on the dial, including the Tudor logo and model designations, is applied in gilt. The dial features luminous hour markers that exhibit consistent patination relative to the handset.

The handset is described as a matching set, designed to complement the dial indices. The luminous material within both the dial markers and the hands has darkened from its original state, which the source attributes to age.

Evidence for this section
  • “Inside, the glossy black 'gilt' dial has aged to various shades of brown, resulting in a wildly tropical patina.”
  • “The luminous plots also shows patina from age and are complimented by a matching handset.”

Bracelet and Appointments

The timepiece is provided with a 'stretch-rivet' Oyster bracelet. The source notes that this component is of a slightly later production date than the watch head itself. The bracelet includes a standard blade clasp mechanism for securing the watch to the wrist.

The combination of the case and bracelet is intended to reflect the specific aesthetic of this vintage reference. The auction description reports the overall condition as strong, citing the preservation of the case features and the distinctive state of the dial as the primary defining characteristics of this specific example.

Evidence for this section
  • “it comes fitted to a slightly later 'stretch-rivet' Oyster bracelet with a blade clasp.”
  • “The Ref. 7928 that we have here dates to circa 1961 and is offered in strong overall condition.”

Open research questions

  • Does the serial number on the case back verify a 1961 production date?
  • Is the bezel insert the original factory-installed component or a later replacement?
