SMART WATCH in Watch for him

Case Shape: It features a "squircle" design—a blend of a square and a circle. This is a very popular aesthetic for contemporary smartwatches (reminiscent of the Apple Watch or certain Fitbit/Amazfit models).
Finish: The case has a matte black or dark charcoal finish, which suggests a sporty yet understated look.
Strap: It’s paired with a black leather or high-quality faux-leather strap. The contrast between the high-tech watch head and the traditional leather strap gives it a "smart-casual" vibe, making it versatile for both the office and a sunset dinner like the one in your photo.

Sensors: While the face is dark, the thickness of the case indicates it likely houses sensors on the underside for heart rate monitoring and fitness tracking.
Display: It appears to have a curved glass or "2.5D" crystal edge, which helps it catch the light beautifully, as seen in your shot.
