HEAT SIPHON HISTORY - August, 1982 - The first digital watch was only 10 years old when the first Heat Siphon (Analog of course) was made. Digital was in its infancy - just 12 months before on August 12, 1981 the IBM PC was introduced. The first Heat Siphon also predates the Apple Macintosh computer which would be introduced 18 months later in the now famous January 1984 Super Bowl commercial
