Cone Base Clock has a dial as wide as the clock itself, balanced on a cone. It is the only Nelson desk clock whose face is larger than its body, and that imbalance gives the design much of its character. It comes from the clock program George Nelson’s office began for Howard Miller in 1947, built around the idea that people read a clock by the position of its hands rather than its numerals. Vitra dates the design to 1947–53 and makes it today from drawings in Nelson’s archive.
HOW IT WORKS
The body is powder-coated sheet metal throughout: dial housing and cone, with no wood or plastic. The slightly concave white dial has light grey hour markers, short black hands, and a red second hand, all exposed rather than behind acrylic. A German quartz movement runs on one AA battery, included. To set the time, remove the back and use the setting mechanism; for a one-hour time adjustment, the minute hand can also be moved directly.
CHOOSING YOURS
There is one version, in white. It is a different clock from the Cone Clock, despite the shared 'Cone' name. That design is a white polyurethane cone with the dial set into its front; the Cone Base places a flat metal dial above a smaller cone and is metal throughout. If you like the cone form but prefer the weight and feel of metal, this is the one for you. We can engrave a message on the back.
DEALER’S NOTES
What we like is the all-metal construction and the exposed hands. Desk clocks without a fixed acrylic lens are easier to service. We usually keep one or two in stock because Vitra’s lead time can be longer than on some of the other Nelson clocks.
Authentic examples carry the Vitra label and use a German movement. We have sold Vitra’s Nelson clocks since 2020 and inspect each one before it ships.
Setting the time
The best way is the dial on the back: turn it so the hands move clockwise. Turning it counterclockwise is fine for setting the hour back in the fall. You may also move the minute hand directly, gently and clockwise. Never move the hour hand on its own; it can damage the gears and put the hands out of sync. The one risk in moving the minute hand is loosening the small nut (open or closed, depending on the model) that holds it in place; a loose nut can eventually let the minute hand come off. If that happens, we sell replacement nuts and hands, and the fix takes a minute.

Replacing the battery
Cone Base clocks run on a single AA 1.5V battery, which is included. The flat negative (−) end goes against the springier of the two contacts. We prefer Duracell, Duracell Procell Constant, or Energizer Ultimate Lithium (non-rechargeable), which is leak-proof. Replace the battery as soon as the clock starts losing time, or make it an annual routine at the time change.

Cleaning
Gently dust with a feather duster or microfiber cloth. For exposed hands, occasionally blow dust from the movement shaft to prevent buildup. To clean stains, lightly dampen a microfiber cloth with a very diluted mild, non-abrasive detergent, and promptly dry. Contact us about any stubborn stains or mechanical issues.
Extending the life of the movement
The clock movement is replaceable, but with good care, it can last 10-25 years. To extend the movement's life, change the battery once a year (during fall or spring time change is a good idea). For models with exposed hands, keep dust from building up on the hands and movement. Do not display the clock in a space that gets intense sunlight & heat throughout the day. Adjust the hands using the dial or knob on the back of the clock only. It's best to rotate the dial so the hands move in a clockwise direction, but it's OK for them to rotate counterclockwise (for example, when setting the time back an hour in the fall).
