The Calibre 89 is the most complicated watch in the world; independently of our mean time (hours, minutes and seconds), it gives or incorporates the followings functions: hours, minutes and seconds of sidereal time, time in a second time zone, time of sunset and sunrise, equation of time, tourbillon regulator, perpetual calendar, century leap year correction, date of the month, century, decade, year, day of the week, months, four-year cycle, sun hand (season, equinox, solstice, zodiac), stars chart, age and phases of the moon, date of Easter, chronograph, split-seconds, 30 minute recorder, 12 hour recorder, Grande Sonnerie with carillon, Petite Sonnerie with carillon, minute-repeater, alarm, going train up-and-down indication, striking train up-and-down indication, striking train stop work, twin barrel differential winding, four-way setting system and winding-crown position indication.

The Calibre 89 was produced to commemorate the 150th Anniversary of PATEK PHILIPPE & C° in 1989. Four watches were produced; the prototype is now exhibited in the PATEK PHILIPPE MUSEUM in Geneva.

The Audemars Piguet, Sunrise - Sunset, Time Equation, and Perpetual Calendar watch takes its place amongst the most sophisticated of timekeepers. Its 11 displays make it an astronomical instrument. It is wound automatically by the simple movements of your wrist. It is available in dial colors 18 carat pink gold, yellow gold, white gold case and AP folding clasp with transparent sapphire case back.

For 100 years, A. Lange & Söhne pocket watches were among the most coveted timepieces in the world - until World War II when A. Lange & Söhne was forced into a 50-year hiatus. In 1990, immediately after Germany was reunited, Ferdinand Adolph Lange’s great grandson Walter Lange re-established the Lange Brand.

Today, Lange is again crafting horological masterpieces “Made in Germany” - indeed,
A. Lange & Söhne watches are now every bit as precious and unique as in the grand old days.

A. Lange & Söhne is the German brand for exquisite mechanical timepieces characterized by unmatched technical ingenuity and the highest level of perfection in craftsmanship achievable by hand.

This watch here is new radiance for a perennial masterpiece.

A horological sensation, the new The GRAND Lange 1 by A. Lange & Sohne is very much in sync with the Lange claim of ‘State-of-the-Art Tradition’

One of the most famous Breguet inventions is the pare-chute. When a watch falls or receives a blow, it is the balance between pivots that are the most likely to suffer, because of their slenderness. As early as 1790, Breguet made them shorter and gave them a conical shape. They are held in place by a small coupelle of a suitable shape, which is mounted on a spring blade. When the watch receives a blow, the pivot, rather than breaking, is dislodged and them returns automatically to its correct position, sliding on the sides of the coupelle. Also called the “elastic” balances suspension, Breguet’s para-chute is the ancestor of the modern Incabloc and all other shock-protection devices.

A. L. Breguet was the first to discover, through his oscillating platinum-weight watch, a formula which would produce a reliable automatic watch. Breguet sold one of his first self-winding watches to Queen Marie-Antoinette.

Inspired by a souscription watch, “La Tradition Breguet” salutes one of Breguet’s most important inventions, the pare-chute. Hand would mechanical movement, caliber 507DR, with straight-line lever escapement, monometallic balance and Breguet overcoil.

The art of transparency

Ever since the dawn of horology, people have been fascinated by the interaction of wheels, levers, and springs in timepieces. Therefore, it is not surprising that gifted watchmakers occasionally took a fancy to showcasing the wondrous inner choreography of their creations – much to the delight of their customers. These were the origins of skeleton watches, the challenging art of cutting openings into plates, bridges, and cocks until the limits of mechanical and functional feasibility are attained. The Patek Philippe Ref. 5180/1 salutes this fine art in a way that by far transcends the notion of the skeleton watch.

Debut of a completely skeletonized and rhodiumed movement

Patek Philippe offers connoisseurs of artisanal tradition such a transparent orchestration of time with the Ref. 5180/1, a skeletonized wristwatch featuring the ultra-thin self-winding calibre 240 movement with a 22K gold mini-rotor integrated into the plate. By affording a fascinating glimpse into the microcosm of hours, minutes, and seconds, it not only captivates the owner with an extravagant setting but also delivers metaphoric insights into the unfathomable fleetingness of time. However, it takes virtually infinite patience, uncommon artistic flair, and the ultimate in craftsmanship to arrive at this point.

Pershing Collection Chronograph by Parmigiani Fleurier

For its first complete collection of aquatic chronographs, there could be no better route to mastery for Parmigiani Fleurier than allying its technical expertise with one of today's biggest boatbuilders: Pershing.

In this new light, the look of the new aquatic timekeeper, especially innovative for Parmigiani Fleurier, took shape: its round and powerfully-shaped case, with stylistic emphases strongly identifying with the Kalpa line (a Parmigiani Fleurier emblem), a uni-directional rotary bezel, rubber chronograph push-pieces built into the loops, 200-metre (660 feet) water resistance, tachometer and rubber or leather straps made to measure.

The second collection of Pershing chronographs is non-limited edition but comes in four dial versions: Graphite, Silver, Blu Metal and Amaranth. This steel-only piece is inspired by the silvery reflections of Pershing yacht hulls, an emblematic, instantly recognisable colour of the Italian brand. The steel metal exhibits contrasts between the satin-finished loops and shiny watch middle band. It incorporates the new Parmigiani Fleurier "house" self-winding chronograph movement Calibre PF 334, fully developed by the Fleurier manufacture.

It is available in steel case and graphite, silver, blu and amaranth colour dials.

The Luminor 1950 Tourbillon GMT and the Luminor 1950 Titanium Tourbillon GMT are equipped with the Calibre P.2005, a movement with a tourbillon escapement, the greatest technical expression of mechanical horology: a complication notable for the difficulty of its construction and the accomplishment of which is the result of the outstanding craftsmanship of master horologists and the most advanced electronic technology.

The special feature of the regulating organ perfected by Panerai lies in the fact that the tourbillon cage rotates on an axis at right angles to the axis of the balance wheel and that it makes two rotations per minute: this rotation, which is faster than usual, ensures greater accuracy, providing the best compensation for the irregular rate caused by the effect of the force of gravity.

The Longines Master Collection in 18 Carat Rose Gold

Since its creation in 1832, Longines is based in Saint-Imier, a small town in Switzerland. Longines always enjoyed a close and trusting relationship with the village that saw it grow and take its place among the worlds leading horological houses.

The world's oldest watch manufacturer in continuous operation since 1755 and founder of the spirit of technical and precious Haute Horlogerie, Vacheron Constantin has been making horological history for over 250 years. From the beginning, it has concentrated on building and consolidating its tradition for technical and aesthetic excellence. This is best illustrated by its timepieces, whose hand-finishing is of an exceptional quality.

Maurice Lacroix is a brand of Swiss watches from the Canton of Jura. The name "Maurice Lacroix" does not refer to an actual person, but was invented for marketing purposes.

In 1975, the company laid the groundwork for its successful corporate history by introducing its first watch under the name of Maurice Lacroix in Austria. Maurice Lacroix now stands for decades of experience in the production of high-quality watches.
