The only way to see this date is to dismantle the clock and movement.
Gilbert and Ingraham also dated many of their clocks, but not in the same manner as Westclox.
That way I got myself another Baby Ben, bringing my collection to three by age 12.
For my 14th birthday I got a book called and there was a picture showing the seven types of Baby Bens.
: Sadly, when Westclox closed it's doors in Norcross, Georgia, in 1999, it was the end of alarm clock manufacturing in the United States.
Most other manufacturers moved their plant overseas by the 1970s. The majority of our restored clocks were made in the US, and we can sometimes offer new-old-stock clocks when we can find them and they are serviceable. It is so common, that clock manufacturers have tried many methods to make adjusting their clocks self-explanatory.
In one direction, moving the lever will shorten the effective length of the hairspring and speed the clock up. Here is the rule: To make your clock run faster, move the lever to F. A movement of the lever by only 1/8" should make your clock run 5 minutes faster or slower.
Some clocks do not have the crescent -shaped opening, but have a "screw head" adjustment.
When I was eight we moved to a new house and my mom and I were looking in the attic and found an old octagon wall clock made by Waterbury, probably dated about 1880. I hung it on my wall and we tried to get it fixed but the repairman couldn’t fix it.I thought, oh boy, I just need four more and I’ll have them all!That summer at an antique store I came across one that wasn’t even in the book, and I thought that was exciting.Westclox did not do this for historical purposes, but to identify a movement for the purpose of supplying repair parts.Slight variations in the movement design, noted by the date, would help identify the exact part needed.
