The Patek Philippe Calatrava ref. 3579 is a watch in a class of its own. This model stands out as a significant departure from Patek Philippe's typical design language of the time...

Audemars Piguet

Folding Clasp

The [RE]Master collection introduced in 2020 pays tribute to Audemars Piguet watches from the past that have been rethought for the present.

Following in the footsteps of the [RE]Master01, which reinterprets a rare chronograph from 1943, this new edition reference 15240SG pays tribute to a Brutalist-inspired watch created in 1960 (model 5159BA). 

Limited to 250 pieces, this model features a 41 mm asymmetrical rectangular case designed in a new sand gold alloy launched by Audemars Piguet in 2024 that is composed of gold, copper and palladium for a warm appearance. The Bleu Nuit Nuage 50 dial is composed of 12 triangular pieces, individually finished with a linear brushed finish creating an interesting play of contrasts.

Equipped with caliber 7129, this extra-thin movement is based on caliber 7121 and has a power reserve of approximately 52 hours.

The watch is delivered full set with box, over-box, original warranty card and manuals.

Vacheron Constantin

During the period spanning the mid-1980s to the early 2000s, the watch industry ehas to face many challenges with the quartz crisis which pushed them to reimagine themselves and move beyond their traditional history. 

Vacheron Constantin responded with the Mercator, launched in 1994 to commemorate the 400th anniversary of Gerardus Mercator’s death. The unusual time-telling display was conceived to resemble a compass, and used a dual-retrograde handset. The design pays homage to the cartographer who created the Mercator projection, which became the standard 'world map' we now recognise.

The dial of the Mercator is made of engraved map lines, this one representing the **Americas**, each lines meticulously filled with glossy black enamel. A subtle yet meaningful detail can be found at the 4 o’clock position on the dial’s edge—a delicate lettering reading "J&L Genbrugge." This tribute honors the Belgian couple responsible for designing and crafting these watches.

With a 36mm yellow gold case, the Mercator features a stepped bezel complemented by robust, matching stepped lugs. The monochromatic palette of the case and dial allow the artistic map design to command full attention.

All Mercator examples utilized the same movement – the ultra-thin self-winding caliber 1120, originally based on a Jaeger-LeCoultre caliber 920 ébauche – which was modified to incorporate a bi-retrograde mechanism for the hours and minutes.

This watch comes with its box, outer-box, original certificate of authenticity and manuals.

With a diameter of 36mm, reference 18239 was produced between 1989 and 2000. A wide variety of dial configurations were offered at the time, including some in semi-precious stone or wood, but all were now flat, unlike the domed dials present on the earlier reference 1803. 

Our model features a silver dial with no luminescent material (“no lume”, which seems to indicate that this watch was intended for the Japanese market) and “SWISS MADE” lettering at 6 o'clock, as opposed to the “T SWISS MADE T” reserved for dials equipped with tritium luminescent material. To match the dial perfectly, the hands also feature no luminescent material.

The most useful improvement for this reference was the addition of a double function for quick date and day setting by means of the crown. This technical advance was made possible by the new caliber 3155, replacing the 3055 used in the previous generation.

As soon as this model was released, Rolex offered a choice of 25 different languages for the day display, English being the most commonly used throughout Europe.

This watch is delivered watch only.

The first Rolex with a second time zone was launched in 1954 under the reference Rolex GMT-Master 6542. This watch was developed in collaboration with the American airline Pan Am to meet the needs of pilots who crossed several time zones in a single trip.

The model reference 1675, introduced in 1959, marked the beginning of a long reign, as it was produced until 1980.
During the course of its production, this model was fitted with various types of dial, which were classified according to different 'Mark' grades. Our model is equipped with a **Mark 5B** dial, distinguished by a narrower, taller Rolex logo than previous versions, and by a singular typography.

The caliber 1575 has a balance speed of 19,800 vph, a power reserve of 48 hours and is not equipped with a quick date-setting function, an improvement that will arrive with the next generation of the caliber 3075. The use of caliber 1575 is recognizable by the order of the hands on the dial, with the GMT hand placed below the hour hand.

The watch is delivered with box, Rolex certificate of origin and 41Watch Geneva certificate of expertise.

The Rolex Explorer reference 1655 was launched in 1971 and remained in production until 1985. It was the first Explorer II model, with an orange 24-hour hand.

It was designed to meet the needs of cave explorers, speleologists and people working in environments where the 24-hour hand was useful for distinguishing day from night.

During the course of its production, this model was fitted with various types of dial, which were classified according to different 'Mark' grades. Our model is fitted with a **Mark V** dial, distinguished by a wider, higher Rolex crown and the words “**T SWISS < 25 T**” on the lower edge of the dial in a large, without serif font. 

Commonly known as “**Freccione**” (“arrow” in Italian), it received its nickname from Italian collectors over the years. This is a very unusual and unique Rolex in style, with alternating luminescent markers, a bright orange 24-hour hand and white hands.

The watch comes with a box, the original Rolex warranty and an expertise certificate from 41Watch Geneva.

Introduced in 1968, Patek Philippe's Ellipse owes its design to no accident. It is based on the golden ratio, considered the “divine proportion” found in nature as well as in the greatest works of architecture and art.

The dials, crafted by specialist Singer for Patek Philippe, offer a simple yet striking contrast between the yellow gold hour-markers and hands and the blue dial with its sunray finish. The dial features a rare “GÜBELIN” signature, an important Patek Philippe retailer historically based in Lucerne, Switzerland, and models bearing this retailer's name are particularly sought-after.

During its production, four different types of dial were used. We have written a full article which you can discover [here](https://www.41watch.com/fr/blog/revue-historique-de-la-patek-philippe-ellipse-n178). this one is the first generation.

The “Sigma σ” symbol present on the dial at 6 o'clock was introduced in the 1970s by the Association pour la Promotion Industrielle de l'Or (APRIOR), and highlights prestigious manufactures that use precious materials for their watches and indicates that the hands and indexes are made of gold, like the dial for this model.

This version of the Ellipse, whose dimensions are very similar to the original model, is equipped with a hand-wound mechanical movement, caliber 215, which appeared in 1974 and is still in use today. Caliber 215 was the first to be equipped with Gyromax, operating at 28,800 beats per hour. This movement boasts remarkable stability over long periods, making it ideal for everyday use.

The watch comes with an extract from the Patek Philippe archives.
