Continuing our study of Waltham’s Model 1870 Crescent Street, the button-set variation represents the next progression following the transition to a stem-wind configuration. Introduced in 1872, around the same time as the lever-set design, this design was ultimately found to be unpopular in the market, especially when compared to the lever-set alternative. The button-set movements required a complex custom case, fitted with a large external button to engage the setting mechanism. As a result, the button-set variation is rather uncommon, being produced in limited quantities for only a few years. The button-set mechanism is derived from Charles V. Woerd’s 1867 patent, which will be covered in more detail tomorrow.
