On June 15, 1886 Joseph H. Eastman and Abraham Craig obtained a patent for a device that permitted winding both springs of a clock on a single arbor known as the tandem wind. As the centennial of this event approached in 1986, a small group of National Association of Watch and Clock Collectors (NAWCC) members, calling themselves "The Tandem Winders" joined together to share their knowledge about the clocks of the Boston Clock Co. and related companies. The results of this research were published several times each year leading up to the 1986 centennial. Ten issues of the "Journal of the Tandem Winders", shown here, resulted in an NAWCC Bulletin article in June 1986 by Harold Cherry, encompassing information from these issues. The Chelsea Clock Museum website is based on Harold Cherry's early research and I am much indebted to him and many other unnamed researchers. Here for your review are these early and rare issues of the "Journal of the Tandem Winders".
