How to open the Omega constellation strap?

I want to change my Omega strap. Where can I change it? About how much?

Hello, here are the steps to change the strap.

1. The section (short section) of the strap with the ring buckle should always be above the watch (when the watch looks at it and the handle is on the right). Unlike a person's belt, the strap specifies the installation orientation.

2, metal strap. When the watch is unfolded, the letters or signs on the strap discount should be consistent with the dial. If it is upside down, it means that the strap is installed backwards. You can open the watch button with your thumb, and the butterfly button can only see whether the logo is consistent with the dial. The strap is upside down, so it must be awkward to open and close.

3, with a discount strap, there will be many holes on the side to adjust the length of the strap. When retracting the strap, you should also pay attention to which side of the strap should not be retracted (retracted and released) by the buckle adjustment part. In this way, the clasp will form a lever force, which makes the strap very easy to open and it is easy to lose the watch.

4. When disassembling the strap section of the metal strap, it is best to disassemble it even, and the left and right buckles must be disassembled evenly. In this way, the clasp can be centered and comfortable to wear, especially for ladies with thin wrists. Pay more attention to this problem when going to the strap section.
