How do I measure a watch movement?
Homer_J
What I want to know is what size movement would I find inside a 40mm
diameter watch case.
What size movement would I need to fit inside a 40mm case?
I keep seeing reference to lignes.
Any help very welcome.

With a very accurate rular or some calipers.

One smalller than 40mm, but there's no real relationship between case size
and movement size. The Omega Speedmaster at 40mm ans Hamilton Pipin ROck chrono at 32mm bith use the same movement.

It's an archaic French unit of measure.
To quote Rob B.:
The LIGNE is equal to the twelfth part of the French Inch, which is approximately 1/16th larger than our own inch. One French ligne=2.25583 or roughly 2ź mm. Thus a 10 ligne movement should gauge 22.5mm. In inches this would measure .8881 as the LIGNE is equal to .0888 parts of an inch. (Note: These days, movement sizes are more commonly stated in millimeters.
