Ever since the dawn of man, the moon has fascinated us. It is said that the moon governs the tides, our moods and even our love influences. Today, it often also governs our watch-buying habits. The finest watch brands in the world have developed some of the most ethereal and technically precise moonphase indications available on the market — and most of the time, we can't stop looking at the disk on the dial.

Moonphase functions, which are often built into calendar watches, indicate the phases of the moon throughout its monthly cycle. Typically, moonphase readouts operate via a small disk within the case that has been painted to depict the different phases of the moon. The disk rotates on a cam in proper time to reveal the moonphases for months, years and even leap years.

Moonphase functions have their origins in the astronomical clocks of centuries ago. The first well known astronomical clock was di Dondi's, created in the mid 1300s, but it was not until the 15th and 16th centuries that clockmakers began creating clocks with moonphases on them. Over the centuries those moonphase indications have evolved and become ever more tiny and precise. In fact, some brands are able to offer moonphase indications that are accurate for 122.6 years before needing an adjustment by a watchmaker.

Additionally, some brands are portraying moonphase indications in larger format, often surrounded by a dial with shimmering stars, or in dark midnight blue enamel hues. Some turn to lapis lazuli and aventurine to present their moonphase beauties. The possibilities are endless — like the night sky. We invite you in any time to see our vast selection of romantic moon and celestial-inspired watches.


Since 2011, German watch brand A. Lange & Sohne has been introducing an exclusive series of watches with artistic dials and top-notch craftsmanship in a collection it calls the "Handwerkskunst." This year, the newest 2017 Handwerkskunst is a delight both inside and outside. With a celestial theme, the 1815 Rattrapante Perpetual Calendar Handwerkskunst watch features a dial of blue enamel and white gold stars created in relief engraving.

The watch offers rattrapante or flyback chronograph functions for timing multiple events. It also boasts perpetual calendar functions, including day, date (no matter the length of the month), month, leap year indication and moon phase indication — accurate for 122.6 years.

The moon-and-stars theme from the dial carries over to the half-hunter case back, where an image of the Goddess Luna is engraved on a white gold medallion surrounded by blue enamel. Open the hunter case back and, via a sapphire crystal, one can view the meticulously finished movement, which has starry night motif.

The watch is powered by the 631-part movement, manufacture caliber L101.1 with 42 hours of power reserve. The 41.9mm white gold 1815 Rattrapante Perpetual Calendar Handwerkskunst is created in a limited edition of just 20 pieces. We have an incredible selection of A. Lange & Sohne watches and invite you in any time to take a look at fine German watchmaking.


Each season the Pantone Color Institute evaluates collections from the top fashion designers at New York Fashion Week and determines the key colors of the next season — reporting them in The PANTONE Fashion Color Report. Generally, the Institute highlights the top 10 colors for men’s and women’s fashions and accessories.

This fall's color palette runs the gamut from pale shades of pink and gray to blue, green, and burgundy — and you can expect to see those colors on watch straps, as well. Hues include Grenadine red, tawny Autumn Maple, pink Ballet Slipper, bright Marina blue and classic autumnal shades of Navy Peony, Neutral Gray, Butterum and Tawny Port.


Many watches today feature mother-of-pearl dials that are shimmering with light and different hues. Generally used on women's watches, mother-of-pearl has become a favorite for men's watches, as well, especially in darker hues. Not all mother-of-pearl dials are natural in color. Dials can be enhanced with color by painting a lacquer or varnish on the back.

The making of a mother-of-pearl dial is not easy. It begins with ultra-thin sheets of mother-of-pearl that are often brittle and can break easily. Those sheets are then cut into orbs, squares or rectangles, depending on the shape of the watch case.

The precise and painstaking task requires expert craftsmen and specialty tools. Often, the job is delegated to a special dial-making company that can handle the pressure. Even then, a dial maker with a strong team can produce only a few thousand top-quality mother-of-pearl dials annually. Watch brands typically buy the base dial already cut and then add their hands, indices or other accents in their workshops.

The best natural mother-of-pearl dial is extra bright white and is sourced in Australia, the South Seas or regions in the Pacific Ocean. Black pearl dials are typically Tahitian in origin. Natural mother-of-pearl is also found in very pale shades of pink, cream and beige. Sometimes the mother-of-pearl is engraved or decorated with sunray or other motifs.


This year marks the 17th edition of the Grand Prix d'Horlogerie de Geneve — a top watch awards event. An expert jury has pre-selected 72 watches that will vie for the winning prize in each category. The winners will be announced at a gala affair in Geneva on November 8, 2017.

Earlier this year, the jury, consisting of 28 multi-disciplinary experts from around the world, selected six watches to compete in each of the 12 categories. Categories include Ladies watches, Ladies High-Mech, Men's, Chronographs, Calendars, Artistic Crafts and more. In addition to the categories, there are some other prizes being offered — for a total of 15 — including the prestigious “Aiguille d’Or” Grand Prix.

Leading up to the final awards ceremony, there will be a traveling exhibition of the 72 watches that will tour to Milan in October at the Palazzo Clerici, in partnership with BMW. They will continue to Mexico, where they will be shown at the retail location of Berger Joyeros before headlining at the SIAR - Salón Internacional Alta Relojería exhibition.

The watches will travel to Taipei, and then on to Geneva, where they will be on exhibit from November 1 to 12 at the Museum of Art and History (MAH). The winning watches will make a final trip Dubai, where they will be exhibited during Dubai Watch Week organized by Ahmed Seddiqi & Sons.

We are happy to carry many of the brands that have made it to the final selection, and will bring news of the winners in November.

Today, so many watch brands offer timepieces with hands or numerals that glow in the dark, but did you ever wonder how they bring luminescence to the dial? Over the years, the materials used to make dials easy to read at night or underwater have evolved, from dangerous and life-threatening substances, such as radium in the early 1900s, to today's safer and  brighter methods.

Easily the most common product used today to make the hands and markers luminous is a material that was developed in the early 1990s: Super-LumiNova. The patented product comes in a variety of glowing colors, ranging from blue to green and even orange. It is made from a mix of materials, predominantly strontium aluminate, and is not radioactive.

Since its creation, the strength of Super-LumiNova has evolved to the point where now, depending on the amount and type used by the individual watch brands, it can be as much as 10 times brighter than earlier materials. The substance is applied in various strengths or coatings to the hands, the numerals, indices or other accents on the dial. It absorbs UV light and subsequently can glow in the dark for hours.

Other materials sometimes used by professional sport watchbands include “gaseous tritium light source” (GTLS) — tiny tubes of tritium placed together to offer an intense brightness stronger than Super-LumiNova. The material is radioactive and so it is hermetically sealed in the tiny tubes. The company best known for supplying these tiny tubes is MB-Microtec. While Super-LumiNova can dim after 20-30 minutes if it doesn't get further UV exposure, the tritium capsules don't dim for 20 years. However, this substance is banned in some countries.


German watchmaking is on the rise. We have more and more customers asking for top German brands, such as A. Lange & Sohne, a premier brand with roots dating back to 1846. The brand was relaunched when the Berlin Wall came down and East and West Germany reunited. The late Walter A. Lange, the great grandson of brand founder Ferdinand Adolf Lange, registered the company in 1990 and showed off its first watches in 1992. The brand soared to success.

The brand regularly creates in-house movements, its own components — including hair springs — and fantastic finished watches in its state-of-the-art manufacture. Known for its cutting-edge creativity and its technical prowess, A. Lange & Sohne also recognizes that women love mechanical watches, too. As such, it creates a host of beautiful, yet highly sophisticated, watches for women.

One of our favorites is the Little Lange 1 Moon Phase watch. The new version is smaller at 36.8mm and is crafted in 18-karat rose gold. It offers outsized date indication, moon phase indication accurate for 122 years before needing an adjustment, hours, minutes in off-center subdial and a power reserve indicator. The watch, with stunning guilloche dial, is powered by the manually wound L121.2 movement with 411 parts — ensuring brains and beauty. Stop in any time to see our selection of A. Lange & Sohne German-made watches.
