The Rally strap uses the same single-fold deploy clasps as other Omega straps. I and many others find it to be the most comfortable, consistent and secure mechanism on the market right now. A few others have found it uncomfortable, so it's really up the wearer.
There are only a few real issues with the Omega. The sizing isn't as precise as the Tag or Breitling methods since you're dependent on holes to secure the strap, but that can be alleviated as long as you're ok with creating another hole using a drill, awl or punch. And the straps vary in fitting depending on material, so straps with exact same flat measurements will either fit larger or smaller on the wrist.
But to answer you initial question if you like the look the Rally strap is pretty fantastic - comfy, secure and sharp. Should look fantastic on the Tin Tin.
