Adams & Perry Lancaster Watch Movement #1369
Record status
Individual type · partial
Period
1876
This movement represents an early American pocket watch design by Adams & Perry, introduced to the market in 1876. The source reports that the movement features a double roller escapement separating an impulse roller table from a smaller notched safety roller table.
The impulse roller is fitted with an unusually wide, flattened pink roller jewel shaped like a tooth, reflecting a design inspired by George Savage's two-pin double roller escapement. The author notes this escapement configuration delegates the impulse action to the safety roller, employing the roller jewel solely for unlocking.

- Visible features
- • Conical balance pivot tapering to a fine point terminates the upper end of the balance staff. • Upper disc features a distinct lateral perimeter notch on its rim. • Lower, wider disc carries a broad, upright, translucent pink rectangular roller jewel pin. • Portions of the underlying balance wheel arm and coiled blued hairspring are visible beneath the roller assembly.
- Identity and Historical Context
- This object entry documents a movement component attributed by the source to an Adams & Perry Lancaster watch movement, recorded under movement number 1369. The source highlights the model as representing the first American-made watch to feature a double roller, noting its market introduction in 1876 when American factories otherwise produced movements exclusively with single rollers. While double roller escapements were already found in certain high-end foreign watches at the time, standard American production did not widely adopt the feature until the 1880s and 1890s, making this early Lancaster production an unusual departure in domestic manufacturing.
- Escapement Mechanics and Source Limitations
- According to the source documentation, the escapement geometry was directly influenced by George Savage's two-pin double roller design. Rather than functioning as a standard impulse pin, the unusually wide, tooth-like roller jewel serves solely to unlock the escapement, with impulse action delegated entirely to the safety roller. Visual confirmation remains restricted to the macro perspective of the balance staff and rollers. The movement plates, escapement wheel, pallet fork, cap jewels, and serial number stamping 1369 are not visible in this image, leaving movement-level identification dependent on the external source article.
- Visual Observations of Balance Staff Assembly
- The provided macro image focuses tightly on the balance staff and roller tables. At the upper termination of the balance staff, a conical balance pivot tapers to a fine point. Below this pivot, the upper disc is visible with a distinct lateral perimeter notch cut into its rim. Mounted underneath is a wider lower disc bearing a broad, upright, translucent pink rectangular roller jewel pin. Beneath this double roller assembly, portions of the balance wheel arm and a coiled blued hairspring are visible.

Research required
- Research required: Only a macro detail of the balance staff and roller tables is depicted; the wider movement plates and serial number are not visible in this image.
- Research required: The source article discusses the escapement generally across images of movement #1369, but serial number 1369 is not directly stamped on this component.
