N.M. Stat. § 30-16-14
Failing to label secondhand watches consists of any person or jeweler failing to identify or specify in any advertising or merchandise display of watches that the watches offered for sale have had any portion of their movements or cases repaired or replaced. Watches which have had the brand name, the name of the maker, the serial number, movement number or any other distinguishing number or identifying mark erased, defaced, removed, altered or covered shall for the purpose of this section be deemed to be secondhand.
For the purpose of this section, sufficient labeling shall consist of any notice affixed to the outside of a watch which clearly and legibly indicates the word "secondhand" printed thereon so that it can be read by a person of normal vision.
Whoever commits failing to label secondhand watches is guilty of a petty misdemeanor.
