How does Omega buckle the strap when it comes to the world of the Observatory?

When wearing, you need to unscrew the screw with a tool, then adjust the strap to the hole with the required length, and then insert and fix the screw.

Omega's new Zunba watch is the world's first Supreme Observatory watch. Equipped with Omega 8900/890 1 Supreme Observatory coaxial movement, there are three materials available: 18K Sedna Gold, 18K Gold and fine steel. This 39mm watch features an iconic dial, which is derived from the famous design of 1952 constellation series watches.
