Hello World

Reference 3417 is one of the very few Patek Philippe references of the 20th century produced exclusively in stainless steel. Introduced in 1958 alongside its sister reference 3418, it was originally fitted with the antimagnetic caliber 12-400, which was later modified and evolved into the caliber 27AM-400 in the early 1960s. Conceived as a true tool watch, the model was designed to meet the needs of professionals working in environments exposed to strong magnetic fields.

The demand for antimagnetic timepieces emerged during the 1950s, notably driven by institutions such as CERN, whose scientists required watches capable of resisting magnetic interference. In response, several manufacturers, including Rolex, began producing such watches, and Patek Philippe soon followed—distinguishing itself by combining technical functionality with refined design. The ref. 3417 was engineered for robustness, featuring a solid stainless-steel case with screw-down caseback, while the movement is protected by a soft-iron inner shield designed to withstand magnetic fields of up to 450 oersteds.

Despite its utilitarian purpose, the reference stands out for its remarkable elegance. The clean, balanced case proportions and restrained aesthetic are complemented by a minimalist dial fitted with applied white-gold baton indexes and the distinctive Bauhaus-style “12”.

During its production, the reference was manufactured with several dial configurations. The present example belongs to one of the later dial series produced for the model and is distinguished by the characteristic “pearl” minute division. Furthermore, the dial does not feature the “Amagnetic” signature, resulting in an even cleaner and more understated aesthetic.

Preserved in excellent overall condition, the watch is accompanied by its original Patek Philippe presentation box, Extract from the Archives confirming both its production and sale in 1970, as well as its original Japanese guarantee booklet, period service documentation, and various historical receipts preserved throughout its lifetime.

Founded in 1858 by Frédéric Boucheron, the Parisian Maison quickly established itself as one of the most prestigious jewelry houses in the world. Renowned for its creativity, exceptional craftsmanship, and bold designs, Boucheron became the first jeweler to open a boutique on Place Vendôme, the historic heart of French high jewelry. Over the decades, the maison has created remarkable jewels and timepieces that perfectly blend horology with haute joaillerie, becoming a reference for refined and distinctive luxury.

The Reflet is one of the most iconic watch designs ever created by Boucheron. Introduced in 1947, the model quickly became the brand’s signature timepiece, admired for its refined proportions and for its ingenious interchangeable strap system, which allows the bracelet to be changed easily without tools.

The present example represents a particularly striking interpretation of the Reflet aesthetic. Crafted in 18-karat yellow gold, the rectangular case is entirely adorned with pavé-set diamonds, creating a dazzling interplay of light across the dial, bezel, and case. The diamond-set dial continues the design seamlessly, leaving only the elegant gold hands to stand out against the shimmering surface.

True to Boucheron’s philosophy of blending high jewelry with watchmaking, this piece feels as much like a jewel as it does a timepiece. The generous diamond setting transforms the watch into a statement of Parisian glamour, embodying the bold creativity for which the maison has long been celebrated.

Despite its luxurious appearance, the watch remains highly wearable thanks to its balanced rectangular proportions and elegant black alligator strap, which enhances the contrast between the deep black leather and the brilliance of the diamonds.

The watch is powered by a Swiss quartz movement and preserved in excellent condition.

The Audemars Piguet Royal Oak Quantième Perpétuel has been one of the brand’s most admired and sought-after models since the mid-1980s. While most examples were produced with either a 36 mm or 39 mm case, the present example, reference 25800, features a refined 33 mm case, offering a perfect balance of elegance, wearability, and technical sophistication.

Introduced in 1996 and produced for only four years, until 2000, reference 25800 is among the smallest perpetual calendar wristwatches ever made. Most likely conceived with the Japanese market in mind, it represents an impressive mechanical achievement, as fitting an automatic perpetual calendar movement inside such a compact case is an extremely challenging task.

The model was produced in only 98 examples across three different metals:

Several dial variations were created during the short production run, making each piece particularly rare and collectible. The present example features a beautiful and warm champagne dial, which perfectly complements the yellow gold case.

Despite its smaller diameter, the case retains a substantial thickness, allowing the watch to maintain a strong presence on the wrist while remaining elegant and highly wearable.

The watch is powered by the automatic calibre 2141/2806 and is preserved in excellent overall condition.

The Rolex GMT-Master reference 16753 was introduced in 1980 alongside the 16750 in steel and the 16758 in full yellow gold, marking a key evolution of the GMT-Master line. Compared to the preceding 1675, the main upgrade was the new automatic Caliber 3075, featuring a higher beat rate and, most importantly, a quickset date function. Despite the technical improvement, the 16753 retained the acrylic crystal, preserving the vintage character of the earlier generation. Unlike the full gold 16758 — which already adopted a sapphire crystal — the 16753, together with the steel 16750, represents the last GMT-Master generation with a strong visual link to the classic 1675 era.

The present example is a highly attractive “Root Beer” configuration in stainless steel and yellow gold. It features the desirable brown dial with applied yellow gold “nipple” hour markers, whose raised conical shape adds depth and warmth, perfectly matching the gilt hands and brown and gold bezel insert. The overall aesthetic remains one of the most charismatic within the vintage GMT-Master family.

This watch boasts a flawless dial and an untouched case, preserved in excellent overall condition, making it a particularly appealing example of this collectible reference.

The Mercator was introduced in 1994 as one of the most imaginative creations of Vacheron Constantin’s modern era, conceived to celebrate the legacy of the great 16th-century cartographer Gerardus Mercator and to showcase the Maison’s mastery of alternative time displays and decorative arts. Produced in limited numbers over approximately a decade, the model is distinguished by its bi-retrograde indication and elaborate map dials, making it one of the most artistic and unconventional wristwatches of the 1990s.

The present yellow gold Mercator features a dial depicting a finely detailed cartographic representation of Asia, Africa, and Europe, inspired by Mercator’s historic world maps. The continents are rendered with remarkable depth and precision, creating a miniature work of art on the wrist. The time is displayed through two compass-shaped retrograde hands: the upper arc indicates the hours, while the lower arc marks the minutes, each hand gracefully returning to zero at the end of its cycle. 

The watch is powered by the ultra-thin self-winding Caliber 1120, adapted to drive the complex bi-retrograde mechanism — a technically demanding system that requires absolute precision to ensure smooth travel and instantaneous return of the hands.

Overall, the watch is preserved in excellent condition, and it is accompanied by its original box, papers and signed loupe.
