The new Spot-On Sundial combines modern functional design with unrivalled accuracy.

3 models of Spot-On Sundial to suit all situations from small urban gardens to large open spaces and public areas

All models can have an engraved message on the side of the gnomon to give a unique gift for an anniversary, birthday, wedding, or special event.

Spot-On Sundial in brass

The main feature of the Spot-On Sundial is the divided gnomon* constructed of two parallel plates with a small air gap. This permits a ray of sunshine to pass through for a few minutes at solar noon, more...

The Unique Line of Light

Spot-on Sundial in Stainless Steel

An interesting dial which gives excellent reflections in the mirror-finished stainless steel, and, with the contrasting matt circle on which the hour lines are shown, gives the appearance of "floating on air" more...

These stainless steel dials are individually designed for their precise location and incorporate engraving text, logos, or drawings agreed with the client.

These elegant and robust dials incorporate the split gnomon, so that every day at solar noon a line of light will shine through the gnomon along the noon line.

When you have decided which sundial you want, you can now buy it in our new online store!

NEW!! The RHS bicentenary sundial?

We have teamed up with the Royal Horticultural Society to produce a large brass sundial with the logo of the Royal Horticultural Society on the dialplate under the gnomon.

This handsome sundial incorporates the "line of light" to enable it to be set up absolutely accurately. The dial is 27 cm. square with a dialplate 25 cm. in diameter, and weighs 5 kg. It makes the perfect present for the keen gardener with a large garden. more.....

The Spot-On Sundial is easy to read

The shadow of the top slanting edge of the gnomon travels round the sundial in a clockwise direction (for our Northern Hemisphere models). This shows the shadow falling exactly on an hour line . The time is 8 am winter time (indicated by the VIII Roman numerals) or 9 am in Summer Time/Daylight Saving Time, more...

General info on sundials

Choosing the correct model for your location

Horizontal sundials need to have the angle between the gnomon (which casts the shadow) and the dialplate appropriate to the latitude where they are to be used. The original 17 cm. square Spot-On Sundial is made in seven models suitable for most of the Northern hemisphere, and there is also one Southern hemisphere model - use this page to help you decided which is the correct model for you. If you want the gnomon angle to be exactly right for your latitude, you can use our advanced setup, but this is not necessary for most practical purposes unless you can be certain that the base is accurately horizontal to better than a half of one degree.
Three of our larger models (two in stainless steel and one in brass) are custom-made for the latitude where they will be placed.

Ordering a Sundial

If you are ordering the original 17 cm. brass sundial, first choose the right model for your latitude. Then decide whether or not you want an engraving. Then go to our shop (if you want to pay by credit card on the Internet) or use our reservation form (if you are paying by cheque or by inter-bank transfer).

For other sundials, please send us an Email saying where you live and which sundial model you are interested in.

Setting up

Detailed instructions are provided for brass and stainless steel sundials, advanced set up for super accuracy, indoor set up.

Note from the Designer

People often ask what is so special about the Spot-On Sundial and how it came to be designed. If you too are interested in this, here is the full story!

Piers Nicholson

New! Polar Spot-On Sundial in brass

An unusual sundial echoing the 3 Millennium sundials designed by Piers Nicholson for the Tylers and Brickayers company of the City of London, more...

The gnomon* is made from two brass plates with a narrow airgap, which produces a "line of light" like the other dials in the range.

The dialplate is in the same plane as the gnomon, so the shadow is a straight line which moves gradually from left to right over the dialplate.

NEW! A Spot-On Sundial for Schools

We have just introduced a new model of Spot-On Sundial designed specially for use in schools to demonstrate the way sundials work or for use indoors on a sunny window sill or in a conservatory.

The dialplate and gnomon are made of acrylic, and the baseplate from styrene. The gnomon consists of two plates with a narrow air-gap, and thus gives the "line of light" which is the hallmark of this innovative design.

The sundial is 7 ins. square, and the markings of the dialplate are closely similar to those of the brass model.
