Origination Classification and Sources

  • New
    Some parts, such as balance staffs and mainsprings, might be available from modern suppliers as new.
  • New Old Stock (NOS)
    A variety of parts are available as "new old stock" from watchmaker estates and defunct watch repiar companies. These parts are typically still in factory packaging but have been sitting in storage for decades. Usually, NOS parts are the next-best option if newly manufactured parts are not available.
  • Donor Watches
    When parts are unavailable as new or new-old-stock, a donor watch may be required to procure the necessary part. A variety of second-hand suppliers exist to serve as "watch junkyards" and can be an effective and affordable alternative.
  • Custom Fabrication
    When repairing a rare or uncommon watch, the necessary part may be required to be fabricated by a competent watchmaker or machinist. This is usually the most expensive option when obtaining parts, but in special scenarios, it is the only feasible option.
