It's About Time
The information below should not be interpreted as an extension of the rules. The official rules in the Rules Manual take precedence. This event is generously supported by the National Association of Watch and Clock Collectors. The 2009 National Tournament winners received one-year NAWCC memberships and were invited to present their It's About Time device (expenses-paid trip for student and coach) at the national horology convention!
