The use of an automatic movement, combined with its anti-magnetic case, solidifies the watch’s historical and innovative standing. While it retains the design cues of Genta’s era, it also updates the line with modern technology.

#### Rarity (11.1% Weight): 8.7/10

**Explanation**: The IW3521 is a relatively rare model, especially due to its compact size compared to modern Ingenieur watches. Though it is not produced in extremely limited numbers, its desirability among IWC enthusiasts and collectors of Genta-designed watches makes it sought-after in the market.

#### Material (11.1% Weight): 9.0/10

**Explanation**: The IWC Ingenieur IW3521 features a stainless steel case, known for its durability and resistance to wear. Additionally, the anti-magnetic inner case provides protection against strong magnetic fields, enhancing the material score. The finishing and construction are top-notch, befitting a tool watch of this caliber, though there are no exotic materials like titanium or precious metals in this specific model.

#### Movement (11.1% Weight): 9.2/10

**Explanation**: The IW3521 is powered by IWC’s in-house automatic caliber 887/2, which offers precision and reliability.

Its relatively modest 34mm case size makes it wearable for various wrist sizes and occasions, while the design remains subtle enough to pair with business attire. Its tool watch functionality means it can handle rugged environments, though its smaller size may not appeal to those looking for a larger, sportier watch.

#### Dials & Design (11.1% Weight): 8.9/10
