COROS Watch Band Size Guide: PACE, APEX, VERTIX & NOMAD Compatibility

Buying a replacement band for a COROS watch should be simple, but model names alone can make compatibility confusing.

A COROS PACE 2 and PACE 3 do not use the same band width. Neither do the APEX 2 and APEX 2 Pro. VERTIX models can require an entirely different size again.

That means choosing a replacement strap based only on the watch family is not enough.

You need to know three things before ordering:

your exact COROS model, the required band width, and the attachment system used by the watch.

This COROS watch band size guide explains the most common 20mm, 22mm, 24mm and 26mm configurations and helps you identify the correct replacement strap for PACE, APEX, VERTIX and NOMAD watches.

COROS Watch Band Size Chart

One of the easiest ways to find the right replacement strap is to start with your exact model.

According to COROS's current compatibility information, band widths vary significantly across the product range.

The important lesson is that watch family does not automatically determine band size.

For example, moving from a PACE 2 to a PACE 3 changes the required width from 20mm to 22mm. Likewise, the APEX 2 uses 20mm while the APEX 2 Pro uses 22mm.

Always confirm your exact model before purchasing.

What Size Band Does the COROS PACE 2 Use?

The COROS PACE 2 uses a 20mm quick-release band.

COROS states that PACE 2 bands are 20mm wide and that the watch can work with selected third-party quick-release straps.

The same width is also used by the COROS APEX 2, creating useful compatibility possibilities between selected 20mm replacement bands.

A 20mm replacement band can therefore be a practical choice for PACE 2 users looking for a different material, color or style.

For running and everyday training, lightweight nylon and silicone are among the most practical options.

Silicone provides a smooth surface that is easy to maintain after sweaty workouts, while nylon provides a softer textile feel and additional flexibility around the wrist.

Before purchasing, confirm that the product specifically supports the correct 20mm quick-release connection.

What Size Band Does the COROS PACE 3 Use?

The COROS PACE 3 uses a 22mm band, not the 20mm size found on PACE 2.

COROS confirms that PACE 3 silicone bands are 22mm wide and use a quick-release mechanism.

This distinction matters because PACE 2 and PACE 3 may look closely related as members of the same product family, but their replacement straps should not automatically be treated as interchangeable.

If you own a PACE 3, look specifically for a compatible 22mm option.

This wider format gives PACE 3 users access to a broad range of sport-oriented replacement strap styles, including silicone, nylon and woven designs.

Is the COROS PACE 3 Band 20mm or 22mm?

It is 22mm.

This is one of the most useful compatibility details to check because shoppers upgrading from a PACE 2 may assume their existing 20mm bands will fit the newer watch.

The PACE 2 uses 20mm.

The PACE 3 uses 22mm.

The width difference means a standard PACE 2 replacement band should not be assumed to fit PACE 3.

What Size Band Does the COROS PACE Pro Use?

COROS PACE Pro also uses 22mm quick-release bands.

COROS states that PACE Pro is compatible with 22mm bands and uses a quick-release mechanism that allows the existing strap to be swapped relatively easily.

This places PACE Pro within the same general 22mm ecosystem as PACE 3 and several APEX models.

However, matching width alone should never replace checking the specific replacement band's stated compatibility.

Connector design, hardware and construction can still matter.

If a third-party product specifically lists PACE Pro compatibility and uses the correct 22mm quick-release format, it is much safer than buying based only on width.

What Size Band Does the COROS APEX 2 Use?

The COROS APEX 2 uses a 20mm quick-release band.

COROS's specifications list a 20mm width for the APEX 2 and a 22mm width for the larger APEX 2 Pro.

That difference is particularly important because shoppers searching simply for a "COROS APEX band" may encounter straps designed for several different generations and case sizes.

For APEX 2:

Band width: 20mm

Attachment: Quick Release

COROS also lists the PACE 2 and APEX 2 within its 20mm compatibility group.

What Size Band Does the COROS APEX 2 Pro Use?

The larger COROS APEX 2 Pro uses a 22mm quick-release band.

COROS explicitly identifies this as one of the physical differences between APEX 2 and APEX 2 Pro.

The difference can be summarized simply:

APEX 2 = 20mm

APEX 2 Pro = 22mm

This is exactly why checking the full model name matters.

A customer who owns an APEX 2 Pro but purchases a generic 20mm "APEX 2 band" could end up with an incompatible strap.

When shopping online, search using the complete device name rather than only the APEX family name.

For example, “COROS APEX 2 Pro 22mm replacement band” is significantly more precise than simply searching for “COROS band.”

What Size Band Does the COROS APEX 4 Use?

COROS's current compatibility guide introduces another important distinction within the newer APEX 4 generation.

The APEX 4 42mm uses a 22mm quick-release band, while the larger APEX 4 46mm uses a 24mm quick-release band.

This means even two watches from the same generation can require different strap widths.

When shopping for APEX 4 replacement bands, always include your case size.

Do not simply purchase something labeled “APEX 4 band.”

Instead, verify whether you own the 42mm or 46mm version first.

This is a useful general rule whenever a smartwatch is available in multiple case sizes.

What Size Band Does COROS NOMAD Use?

COROS NOMAD uses a 24mm quick-release band according to COROS's current compatibility chart.

That makes it different from many of the PACE and APEX models that commonly use 20mm or 22mm bands.

If you own a NOMAD, search specifically for a 24mm strap that confirms compatibility with the watch.

Do not assume that a 22mm COROS band will work simply because it comes from another COROS model.

The correct width remains essential for secure installation.

What Size Band Does the COROS VERTIX 2 Use?

The COROS VERTIX 2 uses a 26mm band.

COROS identifies VERTIX 2 bands as 26mm wide and compatible with selected third-party quick-fit options.

This larger band width matches the bigger, outdoor-oriented design of the VERTIX family.

If you are shopping for a VERTIX 2 replacement strap, look for a product that explicitly states 26mm compatibility rather than assuming that a more common 22mm sports-watch strap will fit.

What Size Band Does the COROS VERTIX 2S Use?

The COROS VERTIX 2S also uses a 26mm band.

COROS lists both VERTIX 2 and VERTIX 2S with 26mm straps, and its comparison information shows both watches using the same width.

COROS also supplies VERTIX 2S with silicone and nylon options, illustrating how different materials can be used depending on activity and personal preference.

For demanding outdoor activity, nylon can provide a lightweight textile feel while silicone provides a smooth and practical sport-oriented option.

Is COROS PACE 2 Compatible With PACE 3 Bands?

Not as a direct size match.

PACE 2 uses a 20mm band, while PACE 3 uses 22mm.

Because the widths differ, a normal 20mm PACE 2 replacement strap should not be assumed to fit a PACE 3.

This is a common example of why upgrading to a newer generation does not necessarily mean your existing band collection will transfer with you.

Always check the replacement band requirements when changing watches.

Are COROS APEX 2 and APEX 2 Pro Bands Interchangeable?

Not as standard replacement straps.

APEX 2 uses 20mm.

APEX 2 Pro uses 22mm.

COROS confirms both the width difference and their quick-release attachment systems.

Because the widths are different, the two bands should not be treated as interchangeable.

Are All 22mm COROS Bands Compatible?

No.

A shared width is useful information, but width alone does not prove complete compatibility.

Several COROS watches use 22mm quick-release bands, including models within the PACE and APEX families. However, COROS's compatibility information still distinguishes specific band products and supported watches.

When purchasing a third-party strap, verify both:

22mm width

and

specific model compatibility

This reduces the risk of buying a strap with the correct nominal measurement but an unsuitable connection or construction.

What Is a Quick-Release COROS Band?

A quick-release watch band uses a small lever connected to the spring bar.

Sliding that lever retracts the pin, allowing the strap to be removed from the watch lugs without using a traditional spring-bar tool.

COROS uses quick-release systems across many current PACE and APEX models.

For example, the APEX 2 uses a 20mm quick-release connection while the APEX 2 Pro uses 22mm.

PACE 3 and PACE Pro also use 22mm quick-release systems.

The system makes changing between different compatible straps relatively straightforward.

Silicone vs Nylon COROS Bands: Which Should You Choose?

Once you have identified the correct band width, material becomes the next decision.

Silicone COROS Bands

Silicone is particularly practical for running, gym sessions and sweaty workouts.

Its smooth construction makes it easy to wipe after exercise, while its flexibility makes it well suited to repeated movement.

For runners who train regularly, silicone is one of the easiest materials to maintain.

Nylon COROS Bands

Nylon provides a softer and more textile-like feel around the wrist.

COROS itself offers nylon alongside silicone on several watches, including APEX 2-series and VERTIX models.

Nylon can be particularly appealing for long-distance running, everyday wear and users who prefer a lightweight strap.

The trade-off is that woven materials can take longer to dry after becoming heavily saturated with sweat or water.

What Is the Best COROS Band for Running?

For running, prioritize secure fit, low weight, comfort and moisture management.

Both silicone and nylon are strong options.

Choose silicone when easy cleaning and quick drying are priorities.

Choose nylon when you prefer a lighter textile feel and additional flexibility.

The exact material matters less than correct fit.

A band that is too loose can allow the watch to move excessively during exercise, while a strap that is overly tight can become uncomfortable during longer sessions.

The ideal setup keeps the watch secure while remaining comfortable throughout training.

How to Measure Your COROS Watch Band Width

If you are unsure about your model, the safest approach is still to identify the exact watch before ordering.

Band width refers to the distance between the inside edges of the watch lugs where the strap connects.

Common COROS replacement sizes include:

20mm

22mm

24mm

26mm

However, manually measuring should be a secondary verification method rather than your primary compatibility check.

Two watches can look similar while using different straps.

Your exact COROS model provides much more reliable information.

How to Find Your COROS Watch Model

If you are uncertain which COROS watch you own, check the device information within the watch settings or COROS app, your original packaging, purchase confirmation or documentation.

Once you know the exact model, compare it against the manufacturer's compatibility information before selecting a replacement strap.

This extra step takes very little time and can prevent ordering the wrong size.

Common COROS Band Buying Mistakes

The most frequent compatibility mistake is shopping only by brand.

Searching for a generic “COROS watch band” is not precise enough because COROS watches use multiple widths.

Another common mistake is shopping only by product family.

“PACE band” can mean 20mm or 22mm depending on the generation.

“APEX band” can also refer to different widths.

Finally, do not assume that every third-party strap with the correct width automatically supports every watch using that measurement.

The product should ideally identify your watch model explicitly.

Is a 20mm Band Compatible With a 22mm COROS Watch?

No. A 20mm strap is narrower than a 22mm connection and should not be treated as a compatible replacement.

Choose the exact width required by your watch.

Find the Right COROS Replacement Band

Choosing a COROS replacement band becomes much easier once you stop shopping by brand alone and start with your exact watch model.

PACE 2 and APEX 2 users should look primarily at compatible 20mm options.

PACE 3, PACE Pro and APEX 2 Pro users typically need compatible 22mm straps.

Newer models such as NOMAD can use 24mm bands, while VERTIX 2 and VERTIX 2S use larger 26mm straps.

After confirming compatibility, choose your material based on how you use the watch.

Silicone works particularly well for sweat-heavy training.

Nylon provides lightweight comfort for running and extended wear.

Other styles can help transition the watch from sport into everyday use.

The most important rule is simple:

model first, band width second, material third.

That order makes it much easier to find a COROS replacement band that fits both your watch and your lifestyle.
