IWC Ingenieur IW3521 Combination
This is a rare IWC Ingenieur IW3521, a stainless steel and yellow gold combination model with a YG bezel and crown.
The Ingenieur model was designed by Gerald Genta, famous for designing the Nautilus and Royal Oak.
This is the IW3521 model, and its 34mm size is exquisite and comfortable to wear.
The movement is a Jaeger-LeCoultre caliber, and the automatic winding rotor uses platinum.
It boasted high water resistance, anti-magnetism, and shock resistance at the time, offering excellent practicality.
Regarding its condition, the dial, hands, and crystal show no noticeable scratches or scuffs.
The bezel, case, and bracelet are also in beautiful condition with only minor scratches. (It has been finished with a light polish.)
Everything is original, and the overall condition appears to be good. (The shape and edges are also well preserved.)
