How to Use Your Vintage Brass Sundial Compass – A Step-by-Step Guide

Thank you for your interest in Aladean’s handcrafted vintage brass sundial compass!

A sundial compass is a remarkable blend of ancient timekeeping and navigation technology, designed for explorers, adventurers, and history enthusiasts. This antique-style brass sundial with a built-in magnetic compass is both a functional outdoor tool and a unique collectible, making it a perfect gift for travelers, history lovers, and nautical enthusiasts.

What is a Sundial Compass?

A sundial compass combines two essential instruments:

1. A Sundial – An ancient device that tells time by using the position of the sun.
2. A Compass – A magnetic directional tool used for navigation.

By aligning the sundial with the compass, you can determine both the time of day and your direction, just as early navigators and explorers did centuries ago.

How to Use a Vintage Brass Sundial Compass – Step-by-Step Guide

Step 1: Find a Sunny Location

A sundial works using the sun’s position, so choose an open space where sunlight is unobstructed. The sundial will not function indoors or in cloudy conditions.

Step 2: Open the Sundial and Adjust the Gnomon

The gnomon is the triangular or curved arm that casts a shadow to indicate time. Lift the gnomon into its upright position so it is ready to catch the sunlight.

Step 3: Use the Compass to Find True North

• Look at the built-in magnetic compass dial and allow the needle to settle.
• Rotate the sundial until the compass needle aligns with the north (N) marking on the dial. This ensures the sundial is properly oriented to work accurately.

Step 4: Read the Time on the Sundial

• Once aligned with true north, the sun will cast a shadow from the gnomon onto the engraved hour markers on the sundial.
• The shadow’s position indicates the approximate time of day. Note that sundials work based on solar time, which may slightly differ from modern clock time.

Step 5: Use the Compass for Directional Navigation

• The magnetic compass allows you to determine the cardinal directions (North, South, East, and West) for navigation.
• Travelers and explorers used sundial compasses in history to calculate their position and estimate travel times.

Additional Tips for Using Your Brass Sundial Compass

✔ Use in an open outdoor space for the most accurate readings.
✔ Ensure the gnomon is fully upright for proper shadow casting.
✔ Account for seasonal variations, as the sun’s position changes throughout the year.
✔ Combine with a modern clock if precise timing is needed.
