The Westclox Clock Company is better known for various versions of Big Ben and Baby Ben windup alarm clocks produced from 1900 to the mid 1980s. But there were other windup models one of which is the Art Deco styled LaSalle series. This is the model 61-C (401) otherwise known as a Dura clock because they have nickel-plated, die-cast zinc cases made by The Dura Casting Corporation in the United States. There are 6 models in the LaSalle series and all use the Westclox type 61 Baby Ben, one day movement.

Gee that old LaSalle ran great….those were the days! (a line borrowed from the theme song to All in the Family)

I have a modest collection of alarm clocks and if something interests me I will buy it. My wife found this Westclox Alarm clock at an antique store in Halifax (Nova Scotia, Canada). At $20 the price was right. It is solid, well made, attractive and partially assembled in Canada.

There is no information on which clock parts were made in Canada and which parts were manufactured in the Peterborough plant through the years

The LaSalle 400 series ran from 1930 to 1934. This is model 61C. The clock measures 3 1/8 inches high. The base is 3 1/4 inches and the depth is 1 3/4 inches.

Inside is a Baby Ben movement. The Baby Ben movement was first marketed in 1910 and first nationally advertised in 1915. The 5-year delay occurred because the company was going through organizational changes and it took 3 years to improve the reliability of the Baby Ben. The patent date on this clock is 1914.

In 1912 Westclox opened a sales office in Toronto, Canada as part of its policy to establish world markets. Somewhere between 1920 and 1922 production began at the plant in Peterborough, Canada. At that time parts were shipped from the LaSalle-Peru plant for final assembly in Canada. Unfortunately, there is no information on which clock parts were made in Canada and which parts were manufactured in the Peterborough plant through the years. Thousands of Big Ben and Baby Ben alarm clocks were manufactured and sold through the 1920s to the 1970s. In the early 1980s production in Canada stopped.

I avoid clocks with radium dials. Since radium has a half-life of hundreds of years even old radium dials are very hazardous. If working on a clock with a radium dial care should be taken to prevent the inhalation or ingestion of flakes or dust which may contain radioactive materials. In the past several years radium dials have largely been replaced by phosphorescent – or occasionally tritium-based light sources.

I took the back cover off and found an inscription indicating that it was last serviced in 1955. The markings are unusual because alarm clocks rarely see servicing and once they stop they are simply discarded or used as paper weights.

That LaSalle may have run great at one time but not now. I can hear it ticking but once set down it abruptly stops. A thorough cleaning is required.

It is a nice piece of Canadian Horological history.
