Ersatzteil - Schlaufe | Schwarz FKM | Robustes Armband | 45 mm / 49 mm

The 45mm size fits my watch perfectly, and the black FKM material is a solid upgrade over my old band—it feels smooth against the skin without any of that sticky rubber texture. Swapping it onto the Rugged Band took me under a minute, so I grabbed a second one to have as a backup.

The loop’s matte black finish matches the rugged band exactly, and it clicks in with zero wobble on my 49mm. Washed it under hot water after a muddy hike and it dried spotless, no stains or stretch.

The black FKM loop swapped in perfectly with my existing rugged band, and the material feels denser than the stock version. It’s held up through a week of sweaty runs with zero stretching, which is exactly what I needed.
