Geochron Technical Information

What Makes a Geochron Tick?

Whether it's the Original Kilburg, the standard, an executive model or one of the boardroom models, every single Geochron made is hand-crafted in the United States.

Each gear is individually hand-cut to ensure optimum synchronization. Each world map is custom printed on state-of-the-art mylar film using specially formulated inks designed to make the map resistant to ultraviolet light. And by the time each Geochron is hand-crafted for shipment anywhere, it has been personally inspected, passing through 24 designated key inspection points.

If you require a little more technical information, here are some other things to know about the Geochron.

Mounting

The Geochron can be mounted on any flat surface in the same manner as a picture. Standard surface mounting brackets are supplied. If you prefer, it can also be recessed into the wall with special flush mount brackets that must be ordered separately. The recess opening required is 33 5/8" x 21 3/8" x 4". Installation instructions are supplied with each unit.

Manual controls

The Geochron has three simple control knobs. Two are located at the base of the unit and are used primarily for the initial setting. One moves the map horizontally to set the time and day of the week. It's also used to determine time of sunrise, sunset and the number of daylight hours at any location at a time other than current. The other knob sets the date indicator and light pattern. A third knob controls the minute dial located at the Geochron's upper right hand corner.

Available housing

The Geochron comes in seven laminate finishes. Princess Plonge' leather is also available, as well as custom wood housings with various accent moldings. Other custom finishes are available at additional cost. Geochron's metal trim pieces are available in a variety of anodized finishes.

Electrical

Geochron is supplied with a choice of standard currents, including 120 and 220 volt, 50 and 60 cycle, etc.

Illumination

Uses two easily replaceable F15T8D flourescent tubes. An electric switch at the base turns the lights on or off without disturbing the timing mechanism.

Protective glass

A brilliant glass pane shields the facing side of the mylar world map.

Map credits
