What is the best strap for the Speedmaster Moonwatch 522.30.42.30.04.002?

How do you change the strap on an Omega Speedmaster Moonwatch?
To change the strap you need specific tools: a springbar tool (thin flat-head screwdriver) and a stable work surface. Insert the tip under the pin (springbar), gently lift to release tension, and extract the pin from the case. Repeat the operation on the other side. For mounting the new strap, reverse the process. If you are not experienced, we recommend assistance from the Casati Milano atelier.
