Bow

Verified

The ring or loop, hinged to the pendant, from which a pocket watch is suspended by a chain, fob, or ribbon.

What it does

Provides the attachment point for a chain or fob, allowing the watch to be carried securely and retrieved from a pocket.

How it works

The bow is typically pivoted on a small pin through the pendant so it can swing freely, and some historical designs include a spring-loaded catch allowing the bow to be swung aside for opening a cover, or removed for case maintenance.

Because it bears the watch's suspended weight and receives ongoing contact from a chain or fob, the bow and its pendant attachment are common wear points, particularly on gold cases where the metal is comparatively soft.

Evolution

A largely unchanged design element throughout the history of pocket watches, though wristwatches dispensed with the bow in favour of a strap or bracelet attached to lugs.

Known variations

  • Fixed bow
  • Swing-out or spring-catch bow allowing removal

Identification for collectors

  • Wear grooves or thinning at the bow, especially near the pivot, are common on well-used pocket watches and a useful sign of genuine age and use

Common failure modes

  • Wear thinning or eventual breakage at the pivot
  • Bow pulling loose from the pendant under strain
