Watch Band Compatibility

Make sure your band fits

Use this page to quickly confirm which connector you need, then shop the correct listing.

Quick tip: If your watch uses standard quick-release pins, you’ll choose by width (20mm or 22mm). Apple Watch uses an Apple-style sliding connector (not quick-release pins).

Apple Watch Apple connector

Apple Watch bands do not use 20mm/22mm pins. They slide into the watch case and click into place.

Apple Watch sizing (choose the correct size group)

Small case group (one band size fits all of these):

  • 38mm — Series 3 or lower
  • 40mm — Series 4–6
  • 41mm — Series 7–9
  • 42mm — Series 10+

Large case group (one band size fits all of these):

  • 42mm — Series 3 or lower
  • 44mm — Series 4–6
  • 45mm — Series 7–9
  • 46mm — Series 10+

If you’re unsure, check the case size etched on the back of your watch.

Quick-Release Pins 20mm / 22mm

These bands use standard spring bars / quick-release pins. Choose 20mm or 22mm based on your watch’s lug width.

20mm quick-release (common compatible watches)

These models are commonly listed as using 20mm standard quick-release pins:

  • Samsung Galaxy Watch 5 (all sizes)
  • Samsung Galaxy Watch 4 (all sizes)
  • Samsung Galaxy Watch 3 (41mm)
  • Samsung Galaxy Watch (42mm)
  • Samsung Galaxy Watch Active / Active2
  • Samsung Gear Sport (SM-R600)
  • Samsung Gear S2 Classic
  • Huami Amazfit Bip / Bip Youth
  • AMAZFIT Watch GTR 42mm
  • Huawei Watch 2
  • Garmin Venu Sq
  • Garmin Vivoactive 3 / 3 Music
  • Garmin Vivomove HR
  • Garmin Forerunner 245 / 245M
  • Garmin Epix 42mm
  • Garmin Approach S4
  • Garmin Move Luxe / Move Style

Always verify: some brands release multiple case sizes with different lug widths. If your model name matches but your case size differs, measure the lug width or check your watch’s specs.

22mm quick-release (common compatible watches)

These models are commonly listed as using 22mm standard quick-release pins:

  • Samsung Galaxy Watch 46mm
  • Samsung Galaxy Watch 3 (45mm)
  • Huawei Watch 2 Pro
  • Huawei Watch GT (many models)
  • LG G Watch (W100 / W110)
  • LG G Watch Urbane (W150)
  • Fossil Q Founder / Q Marshal
  • Fossil Q Wander / Crewmaster
  • Fossil Q Grant
  • Garmin Approach S62 (and some Approach models)
  • Garmin Quatix 5 / Sapphire
  • Garmin Forerunner 935 / 945
  • Garmin Epix 47mm
  • Seiko SKX007
  • Amazfit GTR 47mm
  • Amazfit Pace / Stratos

Always verify: “Garmin / Huawei / Amazfit / Fossil” models often have size variants with different lugs. If you’re not sure, measure the lug width between the two “arms” where the band attaches.

Not sure which one you have?
  • Quick-release pin: you’ll see a small metal pin (often with a tiny slider) holding the band between two lugs.
  • Proprietary connectors: some newer watches use custom lugs/adapters instead of standard pins.
  • Fastest check: measure lug width with a ruler in millimeters (20mm or 22mm).

Want another band?

Make it a matching set

Once you know your fit, ordering a second band is easy—grab a backup for work, travel, or a different look.

Pro move: keep one “daily” band and one “clean” band so you’re never stuck.
