Customers have praised this watch band, saying it fits perfectly and that they're extremely satisfied. Its concave design ensures a perfect fit, something that's difficult to find at other stores.
Concave Machining - Special Technology for Ingenieurs
One of the most distinctive features of the IWC Ingenieur series is its unique case shape, with lugs that curve inward, making it difficult to perfectly fit a standard flat strap.
Why concave machining is necessary
- Unique case shape: The lugs are curved inwards
- In pursuit of the perfect fit: Integrated with the case without any gaps
- Beautiful appearance: Smooth continuity between case and strap
- Improved fit: Natural fit to the wrist
Why it's difficult at other stores
Many strap makers refuse to process the concave shape, stating that it is "difficult to do." The reasons are as follows:
- Requires advanced technology: The difficulty of accurate curve processing
- Complexity of thickness adjustment: Precise adjustment to suit lug thickness
- Risk of failure: Trial and error is difficult with high-quality leather
- Time and cost: It takes several times more effort than usual
