New York Consolidated Laws, Lien Law - LIE § 186. Lien of bailees for hire

Every person, firm or corporation engaged in performing work upon any watch, clock or jewelry for a price shall have a lien upon any such watch, clock or jewelry upon which such person, firm or corporation performs such work for the amount of any account that may be due for such work. Such lien shall also include the value or agreed price, if any, of all materials furnished by such bailees for hire in connection with such work, whether added to such article or articles or otherwise. If such account remain unpaid for one year, after completing such work, such bailees for hire may, upon thirty days' notice in writing to the owner specifying the amount due and informing him that the payment of such amount within thirty days will entitle him to redeem such property, sell any such article or articles at public or bona fide private sale to satisfy the account. The proceeds of the sale, after paying the expenses thereof, shall be applied in liquidation of the indebtedness secured by such lien and the balance, if any, shall be paid over to the owner. Such notice may be served by mail, directed to the owner's last known address, or, if the owner or his address be unknown, it may be posted in two public places in the town, village or city where the property is located. Such notice shall be written or printed. Nothing herein contained shall preclude the remedy of enforcing such lien by action, as provided in article nine of this chapter.
