The Audemars Piguet ref. 5043BC Ultra-Thin is a unique haute horlogerie timepiece from one of the most prestigious watch manufacturers in the world.

This particular piece dates back to approximately 1965 and represents the elegant, very slim line of Audemars Piguet watches, showcasing a completely different face of the brand than the modern, sport-luxury Royal Oak models. It is a discreet, classic, and collectible watch - created for someone who understands the value of traditional watchmaking, manual winding, and timeless elegance.

This timepiece is available only by prior arrangement and individual contact with Dial-House. Due to its value, character, and class, the purchase cannot be made automatically through the shopping cart.

Movement

At the heart of the watch is the hand-wound Audemars Piguet Calibre 2003 movement. This is one of the most recognizable ultra-thin movements in the history of traditional watchmaking.

Calibre 2003 was developed in collaboration with Audemars Piguet, LeCoultre, and Vacheron Constantin. It was an exceptionally slim construction, designed for elegant, top-class dress watches. This movement measured approximately 1.64 mm in thickness, making it one of the thinnest mechanical movements of its era.

The movement operates at a frequency of 18,000 vibrations per hour and offers approximately 36 hours of power reserve. Its very thin construction required exceptional design and execution precision. In watches of this type, not only accurate timekeeping matters, but also the culture of operation, finish, proportions, and historical significance of the movement.

Calibre 2003 was one of Audemars Piguet's key ultra-thin movements and for many years was an important part of the manufacture's offerings. Its significance extends beyond mere technique - it showcases a period when Audemars Piguet built its reputation through complex, elegant, and incredibly precise mechanical watches.

The manual winding emphasizes the collectible nature of the watch. It is a classic, conscious solution highly valued by watch enthusiasts because it allows for daily interaction with the movement and reminds of the traditional nature of such timepieces.

Case and Dial

The watch case is made of 18-karat gold and features a classic, very elegant style. Its diameter is approximately 31.5 mm without the crown and about 33 mm with the crown. The case thickness is approximately 5 mm, and the "lug to lug" dimension is about 35 mm.

This is a very slim watch whose greatest strength lies in its proportions. Viewed from the side, the exceptionally thin case construction is evident, which is one of the most important distinguishing features of this model. The watch is subtle but does not appear accidental or delicate in a negative sense. More substantial lugs and an elegant bezel give it presence on the wrist despite its compact dimensions.

The case has a round shape and a classic form, typical for evening and dress watches. The case back is snap-on and engraved. The crown is original, matching the character of the case and maintaining the elegant, simple line of the watch.

The dial is white and in perfect condition. Its minimalist form perfectly suits the character of the Ultra-Thin model. In watches of this type, it's not about an excess of details, but about proportion, tranquility, legibility, and manufacturing quality.

The entire watch is protected by hesalite crystal, commonly found in vintage watches. Hesalite gives the watch a warmer, more classic character than modern sapphire crystal and harmonizes well with the historical nature of the piece.

Model 5043BC

The Audemars Piguet ref. 5043BC is a model that clearly demonstrates that the brand's history does not begin with the Royal Oak. Before the era of steel sport-luxury watches, Audemars Piguet was primarily known for elegant, complicated, and very thin mechanical watches.

Reference 5043BC was produced for many years in various stylistic variants. The Ultra-Thin versions were an important part of the brand's offerings, especially for customers who appreciated classic evening watches, slim cases, and top-class hand-wound movements.

This is a watch that does not flaunt its size or recognizable sporty design. Its value lies in something else - in the manufacture, history, movement, case material, ultra-thin construction, and elegance that has endured for decades.

Strap

The watch is presented on a strap that complements the elegant character of the model. The strap emphasizes the classic line of the case and ensures that the watch maintains a formal, evening, and timeless appearance.

Upon finalizing the purchase, it is possible to individually discuss the strap, its condition, and any potential replacement with a strap tailored to the client's preferences.

Set and Warranty

The scope of the set, documentation, and any accessories is determined individually before finalizing the purchase.

History of Audemars Piguet

Audemars Piguet is one of the most prestigious watch manufacturers in the world, classified as part of the "Holy Trinity" of Swiss watchmaking alongside Patek Philippe and Vacheron Constantin.

The brand's history began in 1875 in Le Brassus, in the Swiss Vallée de Joux. Jules-Louis Audemars and Edward-Auguste Piguet joined forces to create a manufacture that focused on high-quality mechanical watches from the outset. Audemars specialized in complex movements, while Piguet was responsible for regulation, sales, and business development.

From its very first years of operation, the brand was associated with complicated, precise, and technically advanced watches. Audemars Piguet produced not only its own watches but also movements and solutions for other important watch houses.

Ultra-thin movements, perpetual calendars, minute repeaters, tourbillons, and complicated pocket and wristwatches hold a special place in the brand's history. Audemars Piguet repeatedly pushed the boundaries of miniaturization and technical craftsmanship, creating movements that are still appreciated by collectors today.

Although the brand's contemporary recognition is often associated with the Royal Oak model, Audemars Piguet's history is much broader. For decades, the manufacture was a symbol of elegant, thin, hand-wound dress watches and complicated haute horlogerie timepieces.

Ultra-Thin as part of AP's heritage

Ultra-Thin watches represent a very important chapter in Audemars Piguet's history. They demonstrate the ability to create watches that are incredibly slim, elegant, and technically advanced, without the need to flaunt size or excessive ornamentation.

In models of this type, proportion is paramount. A thin case, manual winding, a classic dial, and noble material create a watch that is best suited as an evening, dress, or collector's timepiece.

The Audemars Piguet ref. 5043BC Ultra-Thin is an example of a watch that showcases the manufacture in its most classic form. This is Audemars Piguet before the Royal Oak era - calm, balanced, technically refined, and very elegant.

Why is this model unique?

The Audemars Piguet ref. 5043BC Ultra-Thin is a watch for someone who is looking for more than a recognizable logo. It is a model for the collector who values history, proportions, manual winding, and traditional watchmaking.

Its uniqueness stems from the combination of several elements: a manufacture belonging to the Holy Trinity, an 18-karat gold case, an ultra-thin hand-wound Cal. 2003 movement, a classic white dial, and a very slim case.

This is a discreet but very prestigious watch. It is not a mass-market or obvious model. Its strength lies in its elegance, history, and quality of craftsmanship. For many people, such watches best demonstrate the true meaning of haute horlogerie.
