The skills and esthetics of the past were combined with modern technology to produce this kit of three working instruments. Rendered with all the care of early craftsmen, and executed in precision die-cut metallic surfaced cardboard, they effectively mirror the heritage of earlier ages. They are:

• NOCTURNAL: A 16th century instrument for converting star-time to sun-time at sea.
• SUNDIAL: To tell time from the lengthening shadows cast by the sun
• PERPETUAL CALENDAR: A functional instrument which is accurate until the year 2016. SW 1 lb.
