Boss Stainless Garmin Fenix 6S Bands Replacement Quick Change (20mm)

The Garmin Fenix 6S takes a 20mm band, and our Boss Stainless band is made to that exact width. It locks into the 6S using the spring-loaded quick-change pins, so you can swap it on or off in seconds with no tools required. The included link-removal tool is only for adjusting the band's length to your wrist — not for fitting it to the watch. "Fenix 6S band size" is one of the most searched questions by 6S owners, so to save you the hunt: 20mm is the number you're looking for.

The band is crafted from solid stainless steel with a smart folding clasp, and comes in three finishes — rose gold, black, and silver. Every order includes the removable links plus a resize tool so you can tailor the fit at home, comfortably suiting wrists from roughly 160mm to 250mm. As a premium alternative to the standard sporty look, it turns the Fenix 6S into a proper dress watch — the kind of upgrade that takes it from everyday wear to a dinner table without missing a beat.

This one is for anyone who wants their Fenix 6S to dress up. It's a favourite with working professionals after a polished look in the office, travellers and retirees who like one watch that suits every outfit, and anyone heading to dinners, weddings or special events. The rose gold finish is especially popular as an elegant option, while black and silver lean classic and understated. If you love the tech of your 6S but want it to look the part off the trail, this is the band for that.

It's easy to mix these up. The Fenix 6S is the compact model with a 42mm case and a 20mm band — the size this product is built for. The standard Fenix 6 is larger at 47mm and the Fenix 6X is larger again at 51mm, and both use wider bands, so a 20mm band won't fit them. To check yours, read the text on the back of the watch case, or open Settings > System > About to see the model name. If it reads 6S — including 6S Pro, 6S Pro Solar or 6S Sapphire — you're in the right place. You can also browse the full Garmin Fenix 6S band range here.

Yes. Every 6S edition — the standard 6S, 6S Pro, 6S Pro Solar and 6S Sapphire — shares the same 20mm quick-change fitting, so this band fits them all with no difference in installation. If you've checked and your watch is actually a Fenix 6 or 6X rather than a 6S, the band width is different — get in touch with our Melbourne-based team via the Contact Us page and we'll make sure you land on the right band for your exact model.
