Section 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.
