[avkxyz]

Hello, 

I have a hard time to remove the BREITLING ETA7750 chrono second hand, 

It is so tight ...I am afraid damaging the hand and chrono wheel inside. 

I need your suggestion ....thank you very much

Mark uses hand levers. Is that what you are using?

Thank you RO63, 
Yes, its the same movement. However, I cannot remove the second counter Hand (the one on the center). It is so tight. I am afraid damaging the parts if I pull harder. .

It can't be that tight, because its a very small small area of friction. However, someone wrote that it's easier to push small hands out with the dial itself (clear plastic applied for protection and loss prevention).

A watchmaker friend of mine says that whenever he services a breitling that has never been serviced before, the seconds hand always comes off the tube. He just puts it back on with a staking set. I don't have any advice, that's just what I've heard about this, not sure if there is a way around it.

I usually remove the main chronograph hand with a presto tool, but not using it as normal, but to simply fit under the hand, and firmly pull upwards.

Absolutely, good advise, otherwise the tube may come apart and you will have to source another hand! This is very important since they are usually tight.

Cheers,

I didn't think you could reach the bottom of the hand tube, if it's exposed then it's by far the best option!

If you refinish your presto tool like I do, you can get the cut out to be the right size to actually grab the tube whilst pulling upwards

It's a good advice indeed. Thank you
