Lockable Watch Band Compatibility

Will a Lil Tracker Lockable Band Fit Your Watch?

Almost every watch falls into one of two categories: it either uses a standard 20 mm or 22 mm spring-bar connection, or it uses a proprietary connector that usually requires an adapter. Use the buttons below to jump directly to your watch type.

Standard Spring Bars

Most GPS trackers and many smartwatches use standard spring bars, usually 20 mm or 22 mm.

If your watch uses standard spring bars, the lockable band attaches directly. Choose the width that matches the watch.

Proprietary Connectors

Some watches use their own connection system instead of standard spring bars.

These watches can usually use the lockable band with a model-specific adapter that converts the connection to 20 mm or 22 mm. Adapters are sold separately.

Choose Your Watch

Direct Fit

Lil Tracker GPS Watches

All current Lil Tracker GPS watches use standard 20 mm spring bars.

Choose the 20 mm lockable band. No adapter is required.

If you are buying for a current Lil Tracker watch, select 20 mm.

Adapter Required

Apple Watch

Apple Watch uses a proprietary slide-in connector, so the Lil Tracker lockable band does not attach directly.

To use the band with an Apple Watch, purchase an Apple Watch adapter that fits your exact case size and converts the Apple connector to a standard 20 mm or 22 mm spring-bar fitting.

Choose the lockable band width based on the adapter’s spring-bar width, not the Apple Watch case size alone.

Amazon listings and compatibility options can change. Confirm that the adapter fits your exact Apple Watch case and accepts the same 20 mm or 22 mm band width you plan to order.

Usually Direct Fit

Samsung Galaxy Watch

Many Samsung Galaxy Watch models use standard spring bars and can accept the lockable band directly. The most common size is 20 mm, although some models use 22 mm or another connection system.

Check the exact model specifications or measure the space where the band attaches before ordering.

Model Dependent

Garmin Watches

Garmin uses several band systems. Some models accept standard 20 mm or 22 mm spring-bar bands, while others use QuickFit or another proprietary connection.

If the watch uses standard spring bars, choose the matching lockable band. If it uses a proprietary Garmin connection, look for an adapter made for the exact Garmin model.

Usually Adapter Required

Fitbit Watches

Many Fitbit models use proprietary connectors rather than standard spring bars.

To use the lockable band, look for an adapter made for the exact Fitbit model that converts the Fitbit connection to a standard 20 mm or 22 mm spring-bar fitting.

Check the Connection

Other GPS Watches and Smartwatches

Most other watches can be evaluated using the same simple rule:

  • If the original band is held in place by a removable spring bar, measure the width and choose 20 mm or 22 mm.
  • If the watch uses a slide-in, clip-in, screw-on, or model-specific connection, look for an adapter that converts it to a standard spring-bar fitting.

This applies to many kids GPS watches, senior safety watches, fitness trackers, and smartwatches from other manufacturers.

Compatibility FAQs

Will the band fit an Apple Watch?

Yes, with the correct Apple Watch adapter. The adapter must fit the Apple Watch case and convert it to a standard 20 mm or 22 mm spring-bar connection.

Will it fit all Lil Tracker watches?

It fits all current Lil Tracker GPS watches. Choose 20 mm.

What if my watch uses a proprietary connector?

Look for a model-specific adapter that converts the proprietary connection to a standard 20 mm or 22 mm spring-bar fitting.

How do I know whether I need 20 mm or 22 mm?

Measure the inside distance between the lugs or check the watch or adapter specifications.

What if I am still unsure?

Contact Lil Tracker before ordering and include the exact watch model plus a clear photo of where the band attaches.

How to Measure for the Correct Band

Measure the inside distance between the watch lugs, exactly where the band attaches. This measurement is the lug width.

Measurement What to Choose
About 20 mm Choose the 20 mm lockable band.
About 22 mm Choose the 22 mm lockable band.
No visible spring bars Check whether a model-specific adapter is available.

Do not choose by brand name alone. Different models from the same manufacturer may use different band widths or connection systems.
