An important change to the Regional Meeting Guide has been approved by the NAWCC Board of Directors at their December 2017 meeting. The new RMG language is as follows: Table holders will offer for sale items primarily of Horological interest and ensure that non-Horological items in the mart are appropriate for NAWCC events and of interest to the members, as determined by the respective event Regional Mart Chair or Regional Meeting Chair. Additionally, certain items, such as barometers and other weather-related gauges, have been permitted at Regional Meetings on the grounds that such devices have often been paired with timepieces throughout history. Music boxes and automata both have mechanisms similar to clocks and are also permitted. No weaponry is permitted.

Stay tuned-in and check back for more updates to this website.

Our best regards,

    Lu & Marion, Co-Chairs
