The 2022 Walking Tours provided opportunities for members of the Roslyn Landmark Society to see unique views of the historic Roslyn Clock Tower.

As described in the 1997 House Tour Guide, the clock is a "Tower Clock," like other clocks that were made in large numbers during the second half of the nineteenth century for churches, colleges, street clocks and clock towers. In their 1879 catalogue, Seth Thomas asks that architects and builders "in making plans for buildings, provisions be made for Tower Clocks. It costs but little in addition, is an ornament, and a public and private benefit."

The clock mechanism is located at the third story, inside the four marble dials. Its label is inscribed:

As for the maker noted on Roslyn's clock, Andrew S. Hotchkiss was one of the principal makers of tower clocks. Hotchkiss had a long and well documented career of making and assembling clocks for Seth Thomas and other clock makers. In 1874 the American Clock Company's catalog noted that a clock made by Mr. Hotchkiss in St. George's Church, New York was destroyed by fire in 1865. Brooks Palmer, in his Book Of American Clocks, lists A.S. Hotchkiss & Co., New York City as having started operations in 1869—1870, and noted that Hotchkiss assembled tower clocks made by Seth Thomas and sold by the American Clock Co.

The American Clock Company was a sales organization based in New York which represented a loose consortium of several independent clockmakers. One of the company's catalogues refers to Hotchkiss' clocks: "designed by A.S. Hotchkiss and manufactured by the Seth Thomas Clock Co. of Thomaston, Conn, [the clocks] are unsurpassed in accuracy of time-keeping, excellence of material and workmanship."

Approximately 150 Hotchkiss designed tower clocks are itemized in the 1874 catalogue, among them clocks in New York City Hall; the Naval Academy in Annapolis; the Centennial Clock in Independence Hall, Philadelphia; and the Jefferson Market Court House in New York.

The clock works are a weight driven Seth Thomas #17, eight-day strike, which has the following characteristics and attributes:

1. A dead beat escarpment (with no recoil, no energy is lost).

2. An eight-foot wooden pendulum rod with a slot for the crutch pin and a 200-pound cast iron round bob at its bottom. The clutch pin's impulse keeps the pendulum going and in return is controlled by the constant rate of pendulum and bob.

3. "Maintaining power," a spring and gear arrangement that keeps the clock going while being wound and prevents escape wheel teeth from being broken. The spring has stored energy from the same weights that drive the clock.

4. A small "minutes only" attached dial which locates the minutes on the exterior faces of the tower.

5. The "motion works," an arrangement of four gears located behind each exterior dial which provided the hour indications on the external faces. The minute indication is supplied directly from the clock.

6. A quad gear arrangement, located right above the clock and connected to it, which transmits the time to all four faces of the clock.
