The new HELIOS WATCH sundial watch - for individualists, outdoor enthusiasts and Sun lovers! Simply open out the gnomon, set the compass to due north and read the time. The cosmic clockwork of the Earth and Sun never stands still and enables the sundial watch to function accurately for ever. Neither batteries nor watch springs are required.

Admittedly the HELIOS WATCH displays its own unique time, naturally occurring solar time. When the Sun is at its highest elevation at midday, it displays 12 noon solar time. It is then true noon, which divides the day into two equal halves, before noon (morning) and after noon. This time relates to the longitude on which we are currently located and it is therefore also called local apparent time (LAT).

If you want to display Central European Summer Time (CEST), then choose the HELIOS WATCH City. This model of the sundial wristwatch is calculated based on your location and can display an approximate CEST.  The watch face will be individually laser-engraved for you, even the town and the geographic coordinates will be included. The gnomon will also be adjusted for the appropriate latitude (34°N - 60°N and 34°S - 60°S).

If your desired location does not correspond with the order address, please inform us of the exact intended location for your sundial wristwatch during the order process. You can also request that we display Central European Time (CET) or solar time (LAT) for your location. Also a different zone time (i.e. GMT or US standard times) can be displayed.
