Manufacture Jean Rousseau, a luxury French leather goods brand, has added a new, more conventional watch strap specification to its NATO-style custom watch straps for the Sony Wena 3, which incorporates the latest smartwatch functions (e-money payment, touch display, Amazon Alexa, activity log, etc.) since January 2021. This is a standard watch strap specification made with two straps rather than a single NATO strap, allowing for a thicker strap at the lug attachment point.
Only the buckle part is a smartwatch

From the front, it looks like a regular mechanical watch.

The leather materials used are four types, including the highest quality Mississippi alligator, known as the "jewel of leather," as well as grain calfskin, goat leather, and Alcantara. Customers can choose their favorite color from approximately 300 colors, including popular vintage colors and metallic brushed finishes.
