The Diesel DZ4026, often called the “Sonar” model, features a unique radar-inspired dial and a minimalist style that sets it apart from standard watch designs.
Distinctive Sonar/Radar Dial
Circular concentric rings with a triangle marker evoke submarine sonar.
 
Swiss Quartz Movement
Reliable and low-maintenance; typical battery lifespan is 2–3 years using standard silver-oxide.
 
Original Black Leather Strap
Often paired with a grain-finish leather strap with black stitching.
 
This watch is in immaculate condition for its age. Original Diesel leather strap shows little wear. It will be very hard to find this vintage watch in such great condition
