As a family of Austrian watchmakers we have spent over 20 years crafting the design of this solid brass and steel equatorial ring pocket sundial in the same purpose-built factory near Graz in Austria - and are proud to say that, because it measures just 60mm in diameter, it meets the official international sizing standard for pocket watches. Made out of solid brass and steel, the Kala Pocket Sundial is a contemporary take on a historical model - the original can be found at the Royal Observatory in Greenwich, London.
