Throwing watches?

In the post “Did avant-garde arts events of a century ago really inspire riots?”, SDStaff Ian writes “Audiences in Boston and New York, not entirely familiar with the political situation in Ireland, didn’t know exactly when to get mad, but they sure did shout, along with throwing watches and potatoes and cigarette boxes.”
Watches had to expensive back then. Was this a common reaction back then? Does the word mean something else?

Maybe it was a typo, and was supposed to be “matches” to go along with the cigarette boxes.
