Whether your watch crown is broken or you
simply want to exchange it for a larger one
that is easier to turn, before you can replace
it you will need to measure the size of the
crown.
Use this guide from Esslinger-dot-com to learn
how to measure a watch crown.
You can tell that your watch crown is a waterproof
one by checking on the watch case for a stamp
of �water resistant� or �waterproof�.
Watches with this marking will have a waterproof
crown.
Watches without this marking will have a dustproof
crown.
Dustproof watch crowns will be lacking the
case tubes you see on watch cases with waterproof
crowns.
But since case tubes can fall out of waterproof
watches, you should always check the watch
case to see if it is marked as water resistant
or waterproof.
You�ll need:
A digital gauge
A watch crown
A notepad and pen
And optionally a watch crown gauge
The first thing you will need to do is remove
the old watch crown.
To do this, you will need to remove the watch
stem.
To learn how to remove your watch crown, you
can check out this video.
Once the old crown and stem are free of the
watch case, lay it out in front of you on
your workbench.
You will start by taking your digital gauge
and using it to measure the outside diameter
of the old crown.
Record the measurement.
This will give you the size of the crown you
will need to order.
Next you will need to find out what the opening
size of your crown is.
You can do this in a couple different ways
either by measuring the case tube sticking
out of your waterproof watch or by measuring
the inside diameter if it is a waterproof
crown.
If the case tube is still sticking out of
the watch case, simply close the jaws around
the case tube and record the measurement.
If the case tube is missing, or if you prefer
to use a different tool, you can use the optional
watch crown gauge and fit the existing watch
crown to the post sizes.
Simply screw the crown onto the gauge until
you find the post that fits the crown perfectly.
You can also measure the crown itself using
your digital gauge.
Simply turn the crown upside down and use
the inside opening jaws to measure the hole
in the crown where the post would usually
sit.
Record the opening size measurement on your
notepad.
The last measurement you will need is the
tap size of the stem and crown.
Take your digital gauge and use it to measure
the outside diameter on the threaded side
of the stem.
If the stem has been damaged and you cannot
measure the threaded portion, you can use
the stamped number on the movement itself
to look up the correct size stem and tap for
the watch.
Once you have all three measurements in hand
you are ready to order your new watch crown.
