Chronograph Watch, Push Pusher Buttons

You will need to know the type (Screw-In, Drive-In or Rectangular Pushers) and the measurements required (head diameter, diameter thread, (b)case etc) to select the right one. Please see the pages and you will see the sizes listed and a diagram on where to measure.

Just having a mm gauge and knowing where or what to measure is important. The skills of a watchmaker who knows how to replace a worn or missing pusher is really going to be needed, unless you are very skilled. If the case has two pushers and you still have the other in most cases it is the same size as the one that is missing. If so then removing a measuring this pusher is the easiest thing to do. If it is not then you will have a harder time determining the correct size pusher you need. Some watchmakers will re-thread the case or use a drive in to get the job done.
