Amanico compiles a comprehensive visual guide to the Tudor 7924 'Big Crown' Submariner, a reference known for its scarcity and distinct features. His post showcases multiple examples, detailing variations in dial markings and case backs, providing invaluable insights for collectors interested in this rare vintage diver.
The 7924 is not a reference we see every day, here or there. For a good reason: The production numbers are quite low. It is said that only 200 were made at the end of 1958, I would say much more, but still, not that many, compared to the 7928 / 7016 / 94010 and 94110.
Let's see those I could find on the net or in the real life.

About the Rolex Submariner Ref. 5510
The Submariner reference 5510 is a notable example within the early production of the model line, distinguished by its "Big Crown" design. This reference was produced for a very short period, making it one of the rarer variants. It represents a transitional phase in the Submariner's development, bridging earlier designs with later, more standardized configurations. Its aesthetic aligns with the functional tool watch philosophy prevalent at the time of its introduction.
The case of the reference 5510 is constructed from stainless steel, featuring a diameter characteristic of its era. It houses an automatic movement, specifically the Caliber 1530, which provides reliable timekeeping. The crystal protecting the dial is made of acrylic, a common material for watches of this period, contributing to its period-correct appearance. The water resistance rating was a significant feature for the model at its release.
This reference appeals to collectors interested in the foundational period of the Submariner. Its limited production run and specific design elements, particularly the oversized winding crown, contribute to its desirability. The 5510 is considered a key reference for understanding the evolution of the Submariner series, showcasing the design language and technical specifications that preceded subsequent iterations.

About the Rolex Tudor Submariner Ref. 7016
The Tudor Submariner reference 7016 represents a significant evolution within the Tudor dive watch lineage, marking a transition from earlier references. It is notable for being one of the first Tudor Submariner models to feature a date complication, distinguishing it from its no-date predecessors. This reference also introduced design elements that would become characteristic of later Tudor Submariners, solidifying its place in the brand's history. It was produced during a period when Tudor was establishing its own identity while still leveraging Rolex's robust case and bracelet manufacturing.
This reference typically features a stainless steel case, housing a self-winding mechanical movement. The case diameter is commonly found at 39mm, a size that offers a balanced presence on the wrist. The crystal is generally acrylic, contributing to the vintage aesthetic and period-correct specifications. Water resistance for this model is rated at 200 meters, aligning with professional dive watch standards of its era. The movement is often based on an ETA ebauche, modified and finished to Tudor's specifications.
For collectors, the 7016 is valued for its historical importance as a transitional model and its robust construction. It appeals to those seeking a vintage dive watch with a strong connection to its Rolex heritage but with a distinct Tudor identity. Variants within the 7016 series may include different dial configurations, such as those with or without the "smiley" self-winding text, which can influence collector desirability. Its position in the timeline between earlier small-crown models and later references makes it a key piece for understanding the development of the Tudor Submariner.

About the Rolex Tudor Submariner Ref. 7928
The Tudor Submariner reference 7928 represents a significant evolution within the brand's dive watch lineage, succeeding earlier references and establishing many of the design codes that would define future Tudor Submariners. Positioned as a robust and accessible alternative to its Rolex counterpart, the 7928 was widely adopted by military forces and civilian divers alike, solidifying Tudor's reputation for producing reliable tool watches.
This reference typically features a 39mm stainless steel case, often characterized by either pointed crown guards (PCG) or square crown guards (SCG), depending on the production period. It is powered by the ETA-based Caliber 390, a self-winding movement known for its durability. Early examples may feature gilt dials and 'smiley' self-winding text, while later versions transitioned to matte dials with white printing. The bidirectional rotating bezel is fitted with an aluminum insert, often featuring a red triangle at 12 o'clock.
For collectors, the 7928 is highly sought after due to its historical significance and the wide array of variations, including different crown guard styles, dial types (gilt, matte, underlined), and military or retailer-signed examples. Its robust construction and classic design ensure its continued relevance in the vintage watch market, appealing to those who appreciate its utilitarian origins and distinct aesthetic.
