FKM RUBBER (SAILCLOTH PATTERN BLACK) - FOR IWC INGENIEUR AUTOMATIC 40

OCT 2026: Fresh out of our handcrafting workbench, our FKM Rubber strap with sailcloth pattern made for the IWC Ingenieur Automatic 40 series. This FKM Rubber strap with sailcloth pattern is fully hand constructed and is made to fit directly to the watch head without needing any additional adaptor, reducing the effective lug to lug measurement and making the watch much more wearable on the wrist. The rubber is soft, durable and requires no breaking in from day one. 

Do note that even though the strap is made of upper FKM rubber material, because it is still held together by hand stitching as well as glue, it is only splash proof and not fully waterproof. This is not a machine mold made rubber strap but an artisan crafted strap

This strap comes with quick release functionality 

**Current turnaround time for crafting as of Oct 2026: approximately 7 business days
