Verichron was the trade name for home and decorative weather instruments marketed by the Harris & Mallow Clock Company.  They had a factory in Howell, New Jersey and were in business around the 1960s-1980s.  Their clock movements, which were mostly electric, were made in South Korea and it is likely the weather instruments came from a similar source.  Their factory in Howell closed around 1992 and was demolished in 2012.
