CNC-machined aluminum case with anodized finish. A premium, sleek wearable designed for your Amazfit Helio Strap.
A CNC-machined aluminum piece, sand-blasted and anodized for enhanced durability and protection. Available in 3 anodized finishes: Gold, Black and Silver.
The adapter is compatible with both the Amazfit Helio Strap and the Amazfit Helio Ring Core.
The wristband comes in two sizes. This is particularly important if you have a very small or very large wrist to ensure a secure fit.
If your wrist measures exactly 170mm, both sizes will work. We recommend S for a snugger fit or L if you prefer a looser feel.

The Strap Forge started with a simple observation: the Amazfit Helio Strap is a great device, but its design is not exactly fashion-friendly. We set out to change that.
This product would not exist without the Reddit community. Every iteration, every improvement came from real feedback.
Yes, our products are specifically designed for the Amazfit Helio Strap and Helio Ring Core.
No, the official Amazfit band is not compatible. Our case is designed to work with 23mm loop-style wristbands with a velcro closure.
You can purchase a compatible 23mm wristband from the Polar Loop store - their bands are fully compatible with our case.
The case and band can handle water exposure such as rain or handwashing. However, we do not recommend prolonged use in chlorinated water (swimming pools), as chlorine can damage the anodized finish over time.
No. The case is made from CNC-machined aluminum with an anodized finish. Anodizing creates a protective oxide layer on the surface that prevents corrosion and rust. This is the same finishing process used on MacBooks and Apple Watches.
Built to handle daily wear for years.

Make sure the aluminum buckle is positioned close to the case, not on the opposite side of the wrist. This makes a significant difference in how the band fits.
