ADDISON — Tick tock. It’s time to learn about your historic clock or pocket watch. On Sunday, Aug. 1, from noon to 4 p.m., members of the Green Mountain Timekeepers will be back in residence at the Chimney Point State Historic Site porch to talk with visitors about historic timepieces.

The timekeepers will offer clock repair demonstrations throughout the afternoon. They invite people to bring their old pocket watches and clocks, or photographs of them, to show the experts. Ask questions about the history of your timepieces, how they work, and how they can be repaired. This program is included in the admission to the historic site ($5 for adults, free for children under 15).

The Chimney Point State Historic Site is located at 8149 Route 17 in Addison, at the Vermont end of the Lake Champlain Bridge. Call 802-759-2412 for information. The site is regularly open Fridays through Sundays, 10 a.m. to 5 p.m., through to Oct. 10.
