The dial is skeletonized with matte grey and gun metal bridges and besides showing the time this special astronomical watch exhibits the number of kilometers the Earth has rotated each day at the equator, created by French clockmaker Gustave Sandoz with a pendulum that beats once every 2.16 seconds – equal to a distance of rotation of 500 meters. There are three different hour discs on a central carrier that rotate clockwise across a black arc with luminous green Super LumiNova Arabic numerals and markers at the lower half of the dial with the minutes indicated by a red arrow with a white luminous inset acting as a minute hand. The active hour is indicated with a red pointer. There are two sectors in the upper half of the dial with an orbital satellite display with wandering hours and minutes; the left-side arch between 9 and 10 o'clock shows the number of kilometers that the Earth has rotated at the equator over a 20-minute period up to a total of 555 kilometers. The arch on the right side between 2 and 3 o'clock shows how many kilometers that the Earth has traveled along its orbit for a total of 35,740k every 20-minutes. It has a 48-hour power reserve at full winding, it's water resistant and pressure tested to 30 meters/100 feet, and the 14mm thick case, dial, and movement are all signed.

Eric Mavani is a first generation jeweler who started in the jewelry business at only 16 years old. Since a young age, Eric became very passionate about jewelry and being a fan of hip hop that only became more evident. Although most jewelers get their start through inheritance or through family, he was determined to succeed on his own and do whatever it takes.

His humble start in the industry had him handing out flyers for a jewelry store in the New York diamond district as a part time job. As he progressed through the years, he later found himself in a salesman position. As the years went by he gained experience and knowledge about diamonds as well as luxury timepieces from working at the jewelry store.

At 20 years old he decided that he would start freelancing and working on starting his career as a Jeweler. He then started walking around the diamond district looking for high quality pieces of jewelry that he can take pictures of and upload to his Instagram page.

At the same time Eric had to gain his trust and credibility in the jewelry industry leading top vendors to supply him with merchandise. With no co-signers or family in the business it was very difficult to manage the business costs but he wouldn’t give up and stayed resilient.

Eric knew that in order to become a household name he had to start supplying big names and A-list celebrities with jewelry to get his name out there.

Eric then networked within city events, and nightclubs where he would find top celebrities to be befriend and foster a future relationship with. He started promoting his brand by putting custom pieces of jewelry on these artists and flying all over the United States to attend exclusive events.

In the early stages of his career, Eric started to gain a buzz in the hip hop industry by working with artists such as Snoop Dogg, 50 Cent & G-Unit, Chris Brown, French Montana, Wale, and YG!

Due to the popularity he gained from the promotions, Eric's orders increased at a significant rate thus creating more buzz around his name. Eric knew that in order to stay on top he had to continue being creative and keep innovating new designs. Eric is now an internationally known and accredited jewelry maker well known for the quality of his craftsmanship.

Eric Mavani has now worked with numerous celebrities across the nation. From A-list singers, actors, athletes and models such as Kim Kardashian, Floyd Mayweather, Diddy, Lil Baby, Pop Smoke, Odell Beckham Jr, Jayson Tatum, Neymar JR, Karim Benzema, Paul Pogba, Young Thug, Gunna, Tyga, 42 Dugg, Jamie Foxx, Scott Disick, Antonio Brown, and more!

As the story shows, Eric started from the ground up and is now making some of the hottest pieces in the industry.

Eric's style has expanded and evolved greatly since then. The end result: jewelry that is luxurious, unique, and timeless.
