Various Waltham Grades

Remember, the model of a watch is the overall design of the watch’s movement.  A good examples are the size and shape of the plates and/or bridges, the layout of the (gear) train, and the design of the vast majority of the parts).

The grade of a watch indicates particular variations between examples of the same model that are usually associated with overall quality.

Variations that distinguish different grades can include:

  • Number of jewels.
  • How well-finished the movement is?
  • Whether the movement has screw-down jewel settings.

The term “grade” is used merely to distinguish between minor variations, and in some cases two different grades are actually identical except for the name.

Waltham used both named grades (“Appleton, Tracy & Co.”, “Wm Ellery”, “Vanguard”, etc.) and number grades (“992”, “No. 81”, etc.) In addition, Waltham used many of the same grade designations for multiple sizes and models, which means that the highest [or lowest] grade for one particular model may not be the highest [or lowest] grade for a different model, even though the names of the grades are the same. Finally, because many grade designations were relative, the comparative quality of some grades changed over the years as new grades were added and older grades were dropped.

 

NOTE: The following chart to give you an impression of the different Waltham grades made. The chart is NOT meant as a tool to help you identify the grade or model of a particular watch.  If you know that your watch is a Model: 1857 – P.S. Bartlett. 18S, 14K, 11J, HC, key wind/key set. Circa 1858.  This chart can be used to find out how the “P.S. Bartlett” grade for that size and model compares to other grades for the same size and model. You cannot use this chart to determine the size or model.  There a many sizes different sizes and models.
