Hello World

This rare and elegant Audemars Piguet timepiece draws inspiration from one of the maison’s most historically significant creations: a unique cushion-shaped minute repeater made in the early 1900s for American businessman John Schaeffer. Echoing that design heritage, this 1990s reinterpretation embodies the Art Deco spirit and timeless sophistication of the original.

While the John Schaeffer Triple Date is more commonly found in yellow gold, this version in 18k white gold is significantly rarer and more sought-after among collectors. With only approximately 100 pieces produced across metals, this particular configuration stands out for both its scarcity and subtle elegance.

The 33 mm cushion-shaped case in 18k white gold frames a clean white dial, punctuated by applied yellow gold radial Roman numerals and dot indexes, outer minute divisions, subsidiary dials for the seconds, the date, days of the week and the months. A sapphire crystal ensures clarity and durability, while the manually wound Caliber 2085 powers a full triple date calendar laid out in an elegant, balanced configuration. A deployant clasp in matching white gold completes the piece, which stands as a quiet but powerful statement of Swiss watchmaking excellence.

Vintage Vacheron Constantin watches exude timeless elegance and represent the highest expression of watchmaking artistry. Their enduring designs reflect the brand’s storied heritage, making each piece a true collector’s treasure. Due to their extremely limited production, these timepieces are exceptionally rare, adding to their mystique and desirability. Renowned for their impeccable craftsmanship, vintage Vacheron Constantin watches showcase the mastery of traditional horology—both in terms of aesthetics and mechanical precision.

This particular example is an exceptionally elegant Calatrava-style watch from the 1940s, most likely reference 4073 according to our research.
It features a 34mm steel and rose gold case that perfectly captures the design language of the era.
The dial displays a warm, refined pink tone that adds a sophisticated touch, with applied baton and Roman numeral hour markers, small seconds at 6 o’clock, and crisp, well-preserved graphics.

The watch is powered by the manual-winding caliber 453, a movement known for its reliability and fine finishing.

The Rolex Oysterquartz is an interesting piece in Rolex’s history. It was introduced in the late 1970s and produced until the early 2000s. What set the Oysterquartz apart from other Rolex watches is its movement, which was quartz rather than the traditional mechanical movement found in most Rolex timepieces. The quartz movement was seen as innovative at the time for its accuracy and reliability. Rolex’s engineering advancements with the Oysterquartz caliber were so significant that the term ‘Oysterquartz’ is prominently stamped on the dial of every Oysterquartz timepiece. The Oysterquartz models were characterized by their distinct angular case designs, which were quite different from the classic rounded cases of Rolex’s mechanical watches. They were available in various styles, including Datejust and Day-Date models.
This Rolex Datejust Oysterquartz reference 17013 is a superb example of the steel and yellow gold configuration, distinguished by its 18k yellow gold fluted bezel and matching gold details on the dial and bracelet. All components are correct and original for the period of production, including the tritium hands and hour markers, as well as the COSC-certified dial—standard for Oysterquartz Datejusts from the early 1980s onward. Powered by the caliber 5035, the watch delivers quartz precision with unmistakable Rolex quality. The angular 36 mm case and integrated two-tone Oyster bracelet give the watch a strong wrist presence, blending technical character with timeless elegance.
This example is exceptionally well preserved, with sharp case edges, a flawless dial, and a tight bracelet showing minimal signs of wear.

Following the challenges posed by the quartz crisis, Ulysse Nardin underwent a revitalization in 1983 under the guidance of Rolf Schnyder, a former executive from Jaeger-LeCoultre. Collaborating with watchmaker Ludwig Oechslin, the brand shifted its focus towards complication and mechanical innovation while also upholding traditional enameling methods such as cloisonné, champlevé, and grand feu. The San Marco collection served as a platform for showcasing these techniques, featuring elaborate portrayals of maritime his-tory, ships, clippers, and architectural landmarks. These intricately crafted pieces, produced in limited quantities due to the meticulous nature of cloisonné craftsmanship, epitomize Ulysse Nardin’s dedication to both artistry and technological advancement.

This Ulysse Nardin wristwatch is part of the prestigious “San Marco” collection, which was considered the pinnacle of Ulysse Nardin’s craftsmanship. The collection aimed to showcase the brand’s expertise in creating highly intricate timepieces, both mechanically and aesthetically, exemplified by the exquisite enamel dial of this particular watch. Limited to just 35 pieces, this watch is exceptionally rare, seldom appearing on the market and it features a finely executed cloisonné enamel dial depicting the Torre di Pisa within the Piazza dei Miracoli, one of Italy’s most iconic landmarks. The watch is housed in a 37 mm yellow gold case, classically proportioned and elegantly styled, with polished surfaces, a stepped lug design, and a rounded bezel.

In addition to its rarity and beauty, this watch is exceptionally well-preserved, with minimal signs of wear on the case and a flawless enamel dial free from cracks or damage. A true work of art, it deserves a place in any esteemed watch collection.

The Rolex Submariner reference 16613 was introduced in 1988 and remained in production until 2009, marking an important evolution in the history of the Submariner line. It was among the first references—alongside the 16610 in steel and the 16618 in full gold—to debut the in-house caliber 3135, a movement that quickly earned a reputation for its reliability, improved shock resistance, and extended power reserve. With a depth rating of 1000 feet (300 meters), a scratch-resistant sapphire crystal, and a unidirectional rotating bezel, the 16613 maintained the technical pedigree expected of a professional dive watch, while introducing a more luxurious aesthetic through the use of precious metal.

This particular example features the classic blue dial and bezel combination, with gold-tone accents that enhance its warm, unmistakable character. The 40 mm case is crafted in stainless steel and yellow gold, matched by a two-tone Oyster bracelet with solid links and a secure flip-lock clasp.
Offered as a full set with the original box, guarantee, and Rolex service paper, this 16613 represents one of the most iconic and versatile iterations of the Submariner—ideal for both everyday wear and as a standout addition to any Rolex collection.
