The Longitude Dial is available in three models to suit a variety of settings, from house to apartment to campus or corporate headquarters. Each dial is engraved with the desired inscription and special occasions, marked with a unique serial number, and supplied with a signed and dated certificate of origin.
The Longitude Dial rediscovers time as a measure of the rhythm of nature and expresses it by balancing art and science. In doing so, it has an eternal heart of its own, one that belongs to our family.

Measuring about 12 inches (30 cm.) in diameter, the Terrace model can be used in a sunny indoor area, such as an atrium, and easily moved to a sun porch or garden terrace of the same house. With the aid of its bubble level, the Dial’s three screw feet can be easily adjusted to accommodate different surfaces. Because it can be personalized in many specials ways, it is a unique gift for an anniversary, the birth of a child, a wedding, or just to remind someone that you love them.
I look at my wristwatch a hundred times a day without thinking, then immediately forget what time it is. But when I go out to consult my Longitude Dial, observe the shadow of the gnomon, and adjust for the equation of time, I feel a delightful sense of accomplishment and enrichment. Time has become more meaningful to me for the experience of telling it in this beautiful way.

Owner of Longitude Dial No. 4 (Garden style)
For hundreds of years, sundials have been used to complement the elegance and beauty of a garden, silently recording the passage of time and the natural cycles on which life on Earth depends. Sometimes, they include a verse from a poem or other literary quote meaningful to the owner. The Garden-style Longitude Dial is about 23 inches (58 cm.) in diameter and is mounted on a pedestal secured on a firm foundation. A compass rose can also be provided with features, such as the direction and distance of significant places in the life of the client.
The Garden Dial requires at least two site visits, the first is to discuss with the client the desired features and other details, choose an appropriate location that will gives an optimal amount of sunshine throughout the year, and resolve the foundation requirements with a local builder to the specifications provided; on the second visit, after the foundation and the dial parts are ready, the pedestal and the dial will be precisely leveled, oriented, and secured in place.
ranges in size according to the design details of the commission. The smallest so far has been about 3.3 feet (1 meter) in diameter, and the largest about 16.4 feet (5 meters). Like the Garden Dial, it is installed on a custom pedestal in a location that promises abundant sunshine and can be designed to provide calendrical information obtained from the Sun’s apparent motion. The compass rose that surrounds these dials provides a unique opportunity to introduce other information of general interest, such as the direction and distance of cities throughout the world.

Note: This work was commissioned by the State of Guerrero under the administration of Zeferino Torreblanca and funded by the Federal Government of Mexico in 2010 to commemorate the Bicentenary of Mexico’s Independence. During the next state administration, which came to power in 2011, the funds were used for other projects. Therefore, the construction and final installation cannot be completed until additional financing is forthcoming.
Cielo y Tierra (Heaven and Earth) — the name given to the Chilpancingo Dial — was designed and constructed to commemorate the bicentenary of the Congress of Chilpancingo and Mexico’s first declaration of independence. The Congress took place in the Catedral de Santa María de la Asunción in Chilpancingo. It was there, on September 13, 1813, that José María Morelos presented his “Sentiments of the Nation”, a now famous document that laid out the principles of a constitution to establish Mexico’s independence from Spain.
This monumental sundial was chosen to mark this seminal event in Mexico’s history, because it combines two elements linking the past and the present: astronomy (which played such an important role in the pre-Columbian world) and time measurement (a foundation stone of our present civilization). With the armillary hemisphere (representing the heavens) arching over the dial (symbolizing Mother Earth), it illustrates the universe known to the Olmecs, Aztecs, and other ancient civilization — and hence its name: Cielo y Tierra.
The five-meter diameter dial encircles the map, and the water in the oceans flows off the edge into the surrounding channel. The fifteen-meter armillary hemisphere arching over the dial supports the gnomon, the shadow casting wire that indicates the time on the hour circle. The compass rose terrace has been designed to appear like an island, echoing the original island city of Tenochtitlan, the capital of the Mexica civilization. The water surrounding the compass rose flows from under its perimeter into the waterfall and moat. Like the causeways that connected Tenochtitlan to the mainland, steps and bridges provide access to the sundial from the North, East, and South, and ramps lead up to the West entrance.
