Vertical Dial

Sir Christopher Wren is just one of many architects to have taken on the three-dimensional challenge of the vertical dial (latitude, longitude and angle to the ecliptic). Humble yet historic, this piece represents quiet elegance, offering a thoughtful and dynamic embellishment to vertical surfaces.

Design details

Whilst clocks keep time, the vertical dial historically sets time. Sundials have marked human timekeeping as far back as 1500 BC, setting the pace of public life and spaces in the ancient world.

These vertical dials, however, are site-specific to your wall, your house, your longitude, your latitude, and to your world.

The declination of the wall to the sun is carefully measured to ensure accurate time-keeping.

Known as dial furniture, the dial can be adorned with the name of your house, year, motto, or quotation.

Product information

The method of installation will depend on the material, scale, and location of the vertical dial. For mainland UK clients David Harber undertake the installation. For international clients detailed instructions will be provided but rest assured it is not a particularly complex procedure.

The finishes used on the Vertical Dial will exhibit some natural weathering with age, however, periodic cleaning will help preserve its beauty. We would recommend that it be cleaned at least once a year with only warm water and a soft cloth to remove any detritus. Use of any abrasive cleaner will damage the finish and must be avoided. Maintenance instructions will be issued on installation.
