ADDISON — It’s time to learn about your historic clock or pocket watch. On Sunday, July 20, from noon to 4 p.m., members of the Green Mountain Timekeepers will be on the porch at the Chimney Point State Historic Site in Addison for this “Blast from the Past” to talk with visitors about their historic time pieces. Repair demonstrations will be ongoing all afternoon.

The Society invites people to bring their old clocks, pocket watches, wristwatches, or photographs of them, to show the experts on hand. It’s always fascinating to see what turns up. Ask questions about the history of your timepieces, when they might have been made, how they work, and how they can be repaired. This program is included in the admission to the site— $6 for adults, free for children under 15.
