Waltham Grade 220, 1894 Model

There's been an interesting repair to the mainspring arbor pivot here in the main plate. It has been punched around the edges to spread the metal and close the hole some. The hole probably got worn to an elongated state allowing the barrel to run uneven or out of flat and perhaps it was jamming up.

All sorts of interesting repairs are found in old watches.

See more here.

This is why it is important to get a watch service. Grit gets in the pivots and causes wear over time. Running a vintage watch without getting it cleaned is just like running a car without changing the oil

 Here are a few details on the winding/setting mechanism found on many vintage Waltham products.

The moving parts are covered and held by a simple round clamp and one screw.

There's plenty of character to be found in this dial.
