Hi,how can i remove the lether strap CFM00003B .don´t now how to remove the pin from the lug.thank´s.

Depending on the model, if it is one that has a leather strap, then they are held in place with spring-bars that go through the ends of the band protruding out of each end. the points then insert into holes in the bezel lugs and thus hold the band in place.
The best method is using a tool made for this which you can pickup at any Harbor Fright Tools store if there is one in your area. Alternatively, use a small screwdriver and insert it against the inside of the lug where the band rides against. As you begin to pry downward away from the lug, you will see the spring-bar. Look for any ridges on the bar that can be used to pry further... it's really trial and error and use caution to not damage your band. another way that works quite well is a not-too-sharp knife. Again insert it between the band edge and the inside of the case lug and with pressure against the pin, pry downward away from the lug... the ping should disengage

Straps are usually held in place by two spring loaded metal pins between the two lugs on either side of the strap. Look at the ends near the lugs you should be able to see them, use a very small flate blade srewdriver to pull back on the pin and once you get it, it will pop out of the hole its in.

I don't know for the swatch specifically but all watches are roughly the same beast. If you look at the side you will notice small pins on the band. With a very small jewelers screw driver and some light tapping you can pop the pins out. The end connections near the watch and then on the clasp side are usually spring loaded which can be removed with a tiny flat blade as well. Just tap out the pins and keep track of them, you will need to tap them back in once you have removed the extra link to make this smaller.

take a pish pin, inside had a arrow , that is the big head out , cotter pin. tap on pi opposit hole. pin comes out and pull . when inserting in pin tap down pin until it is in band.

It depends on the strap as there are several different types.
But I suspect the one you have has pins that go through the whole metal wrist band.
You need a special tool that pushes out the pin, these normally only come out in one direction.
There should be very small direction arrows on the back of the strap if that is the case.
When putting them back in again they must go in the correct direction.
Look on ebay for wrist watch strap removal tool, looks like a mini vice with a small handle and pin pusher the other end.

You will probably need an assistant to remove your watch.

If you still can't get the watch off, let your assistant use a small screwdriver to remove the spring loaded pin that holds the strap to the lug of your watch.

( This can be done by putting a small tension on the strap pressing the screwdriver against the pin and pushing it in the desired direction. Some practice may be required!

Some clasps have holes in them to allow you to adjust the straps in smaller steps than removing links.

It sounds as though yours in one of these.

The pins are spring loaded just like the ones used to fasten the strap to the lugs of the watch, so you can apply a probe to one end of the pin with one hand, while applying a gentle force in the direction you wish the strap to go with the other hand.

Then do the same with the other side and repeat as needed.

Get pen knife and insert the blade between the watch strap and watch lug from the bottom side. Pry the springbar inwards using lever action. This must release the springbar.

Rate me, please.

Strap is attached to case by spring pins. Both ends of spring pin are inserted into holes into the case lugs,
. Take the knife and push the spring pin end inwards to release the watch strap.
Do not forget to rate, please.

Take a VERY close look at yor watch and you should notice a few tiny buttons. One of them should correspond to MODE, another to SET and so on- depends on how many your watch has.
Use a pin or a needle to push them and find out the settings procedure.
If you cant find buttons on the case sides, examine case back. They can be hidden between the lugs, so, the strap should be taken off.
Remember- there are no watches in existance without adjustment features. Even atomic clock needs to be adjusted after a few million years of work:))

Good luck.
