Hamilton WW2 Ship Chronometer "Trip Spring"

This is a "trip spring" for the spring detent (shown in picture to its right) for a Hamilton model 21 movement (last picture). Over time the end of the trip spring wears and it must be replaced.

Note that we service these chronometers and have more parts.  Email us with your needs. We also have the repair manual and can download you a copy.
