In the year 1849, the engineer Charles Shepherd Junior (1830–1905) patented a system for controlling a network of master and slave clocks using an electric way, the galvanism. Shepherd installed the public clocks for the Great Exhibition in May 1851. By August 1852, he had built and installed the network of clocks and cables in the Royal Observatory, in Greenwich, London.

The Gate Clock originally indicated astronomical time, in which the counting of the 24 hours of each day starts at noon. The clock was changed in the 20th century to indicate Greenwich Mean Time (GMT), in which the counting of the 24 hours of each day starts at midnight. Currently, the Gate Clock continues to show Greenwich Mean Time, and it does not show daylight saving time.

A few meters behind the clock, pass the Greenwich Prime Meridian Line, based at the Royal Observatory. This meridian was established in London by Sir George Airy in 1851. By 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps.

In October of that year, during the International Meridian Conference, this meridian was selected as the Official Prime Meridian of the world.The Greenwich Prime Meridian is still now the worldwide Time zone reference.

The original idea to create a wristwatch version of the Shepherd Clock, bornt in the summer of 2014, in London. During a visit of the Royal Observatory of Greenwich, we remained fascinated by the Shepherd gate clock and its history. That's why we decided to search for a wristwatch replica of this historical masterpiece.

To our great surprise, we found out that no one had ever made a wrist version of this clock, considered by many people the world's most popular GMT Clock. After a careful analysis, we realized there were several factors preventing an easy replica of this watch from being marketed. The first one is the particular dial and ring shape, both difficult to be properly executed in small dimensions. The second, but perhaps most important reason, is the movement: The clock has got a 24h movement with hours and minute in the main dial and seconds in the high positioned subdial. There are watches with the 24h movement mechanism in the market, but nobody with this very particular feature. Later on, during the design phase, we added the 12h movement version, to share with the twelve hours watch users the unique design of this famous clock.

The movements mounted on the GTG are of two type:

24H MOVEMENT

Characterized by a 24 hours and minutes hands on the main dial, plus the small second hands on the high subdial. The mechanism is a fully-automatic self winding type with the GTG logo engraved on it.

12H MOVEMENT

Characterized by a 12 hours and minutes hands on the main dial, plus the small second hands on the high subdial. The overall dimensions are the same of the 24h version, as the fully-automatic self winding mechanism, with the GTG logo engraved on it.

Each movement is tested in the Italian Assembly Department, responsible for the manufacturing of the watches and for the quality control.

The two movements come with the same dimensions: 30.4 mm diameter and 7.4 mm thickness.

Exclusively for the Kickstarter campaign, we are proud to announce that the watches will be numbered. Every backer from Kickstarter will have her/his own watch engraved at no additional cost.

The incision will be on the movement and it will follow the production order - from the first baker's watch with the lowest number (e.g. “001/ ----“), until the last one.

The numbered limited edition won’t be available for watches sold after the Kickstarter campaign.

The first design step consisted in defining a 3D cad watch-case that could maintain the original shape of the Shepherd Clock, with a luxury design that could exalt its character. For this reason, the case is linear, without shapes and with the crown in the bottom (at "6 hours" in the 12h model, at "12 hours" in the 24h model).

The ring is probably the most particular and distinctive part of this watch. Its colored in black for the standard GTG model, as the original Shepherd one. To preserve the original layout, we decided to use the 316L Stainless Steel with Black IP coating, a modern treatment used from many of the most luxury watch manufacturer.

To create a symmetry in the watch, even the exhibition case on the back is the same color. There is also a more classical version available, with natural 316L Stainless Steel.

The next steps was to create prototypes in ABS material, with a stereo lithography 3D printer. This test was crucial in verifying the space required for the crown setting and the strap positions.

Another distinctive and particular element of the clock are the hands. We have made photo chemical milling prototypes of these ones as well.

Once the dial size was defined, we moved into designing the dials. In order to obtain a collection of watches suitable for different occasions and for people of all ages, we designed three different dials versions, in glossy or galvanic surface finish:

  • the modern clock version - 24h
  • the modern clock version - 12h
  • the 1910's clock version - 24h

We decided to add the 12h version to share the unique design of this famous clock with people that prefer this kind of movement.

While the back glass of the watch is the same for all the combinations, we decided to give each customer the possibility (at the same price) to choose between two type of frontal glasses:

  • domed sapphire coated classic glass (3 ATM water resistant)
  • high domed acrylic crystal vintage glass (dust resistant)

The Greenwich Time Gate logo is inscribed on the Ardillon Buckle and on the Deployant Buckle ("butterfly type" - STRETCH GOAL).

The last step was to find the straps. Due to the high amount of combination available until this point, it was necessary to choose high quality straps suitable for different combinations.

Our choice consisted in 4 main categories:

  • Vintage genuine Italian leather straps: light brown, dark brown, black
  • Bull genuine Italian leather straps: white, brown, black
  • Crocodile Print genuine Italian leather straps: light brown, dark brown, black
  • Real crocodile Italian leather strap, black

In addition to these models, we have the Silicon strap (black) and the Nato type straps (4 colors), available for everyone as STRETCH GOALS.

The collection is divided into four main models:

  • the GTG 12h Glossy Dial, a variant of the classic 24h Shepherd Watch
  • the GTG 24h Glossy Dial, the classic one inspired to the Shepherd Watch
  • the GTG 12h Galvanic Dial, with variant of the luxury galvanic finish dial
  • the GTG 24h Galvanic Dial, with variant of the luxury galvanic finish dial

Risks and challenges

During the past two years we employed our energies and time to make our working prototypes reach production quality. Prior to our Kickstarter campaign, we have been rigorously testing our products and we're confident that we'll meet or beat our projected delivery dates.

Our manufacturers stand ready to activate production as soon as we meet our Kickstarter funding goal. In addition, we built in extra time for the manufacturing process and are confident we will ship by the projected dates. We will always keep you informed if (in the rare chance) things take longer than planned.
