Petal Clock was designed at George Nelson Associates in 1957 and first called the Lucky Clover. Four black petals radiate from a brass hub, while the wall shows through the gaps as a four-pointed star. The points fall at 12, 3, 6 and 9, with brass markers on the petals for the hours between. The result is part clock and part cutout: the wall itself becomes part of the dial. Vitra makes the Petal from drawings in Nelson’s archive.
HOW IT WORKS
The hour hand is a white circle with a slender triangle, a shape unique among the Nelson clocks. The minute hand is long, tapered and white, and the second hand is gold. A German quartz movement behind the face runs on one AA battery. The time is set with a dial on the back, and the clock hangs from a single nail or screw.
CHOOSING YOURS
Vitra makes the Petal in one version: black lacquered wood petals with brass details, 17⅝″ across. You will not choose a finish, but you will choose a wall, because the star is made from whatever sits behind the clock. On white or pale plaster, the shape reads sharply and the clock looks more graphic. On a dark wall, the petals recede and the brass becomes more prominent. Wood paneling or wallpaper fills the opening with its own grain or pattern.
DEALER’S NOTES
Most people who choose the Petal start with the black-and-brass palette, but the detail we like most is easier to miss in photographs: the petals turn up slightly at the edges, so the clock catches light and shadow rather than lying flat against the wall. The petals are lacquered wood rather than metal, which keeps the clock lighter than its appearance suggests.
We usually keep the Petal in stock and inspect each one before it ships. Authentic examples carry the Vitra label and use a German movement. We stock movements, hands, and the nuts that hold them; see our replacement guide. We have sold Vitra’s Nelson clocks since 2020.
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. If taking the clock down is awkward, 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
All wall clocks run on a single AA 1.5V battery, which is included. The flat negative (−) end goes against the springier of the two contacts on the movement: angle that end in first, then press the battery down. 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 better, make it an annual routine at the spring or fall time change; the old battery is usually still good for a remote or another device.

Cleaning
Gently dust with a feather duster or microfiber cloth. Be careful not to knock the clock off the wall. 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 easily replaced (see Hand / Movement Replacement Guide), but with good care it lasts 10–25 years. Change the battery once a year; the fall or spring time change is a good reminder. Keep dust from building up on the hands and the movement shaft. Keep the clock out of strong sun and heat. Set the time with the dial on the back whenever you can, and if you move the minute hand instead, keep a light touch and leave the hour hand alone.
