How to Identify Your Apple Watch Model, Size and Choose the Perfect Band

Not sure which Apple Watch you have, or which band will fit? This guide helps you find the right connector size, measure your wrist and change your band in seconds.

Step 1: Find your case size

Turn your Apple Watch over. The case size (for example 41 mm or 45 mm) is engraved on the back, together with the model.

Step 2: Check your connector

Our Apple Watch bands come in two types:

1. Bands with a connector choice. On the product page you choose 38 / 40 / 41 mm or 42 / 44 / 45 / 46 / 49 mm. The table below shows which one fits your watch.
2. Bands with a universal connector, like our wrap bands. The universal connector fits both sizes, so there is nothing to choose. You only pick your wrist size, if the band offers one.

Not sure which type you are looking at? If the product page does not ask you to choose a connector size, the band has the universal connector.

Which connector do I choose?

Your Apple Watch	Choose
Series 1, 2, 3 38 mm case	38 / 40 / 41 mm
Series 1, 2, 3 42 mm case	42 / 44 / 45 / 46 / 49 mm
Series 4, 5, 6 and SE (1st, 2nd and 3rd generation) 40 mm case	38 / 40 / 41 mm
Series 4, 5, 6 and SE (1st, 2nd and 3rd generation) 44 mm case	42 / 44 / 45 / 46 / 49 mm
Series 7, 8, 9 41 mm case	38 / 40 / 41 mm
Series 7, 8, 9 45 mm case	42 / 44 / 45 / 46 / 49 mm
Series 10, 11, 12 42 mm case	38 / 40 / 41 mm
Series 10, 11, 12 46 mm case	42 / 44 / 45 / 46 / 49 mm
Ultra, Ultra 2, Ultra 3, Ultra 4 49 mm case	42 / 44 / 45 / 46 / 49 mm

Good to know: Apple reused "42 mm" for the small case of Series 10 and newer. On bands with a connector choice, a 42 mm Series 10, 11 or 12 takes the 38 / 40 / 41 mm connector. Only the old 42 mm Series 1, 2 and 3 takes the larger one.

Step 3: Measure your wrist

1. Use a flexible measuring tape or a strip of paper.
2. Wrap it snugly around your wrist where you normally wear your watch.
3. Note the measurement in cm.

Wrist sizes differ per band, because every design is made and fits a little differently. Always check the size options on the page of the band you like and choose the one that matches your wrist.

Between two sizes, or outside the sizes shown? Please contact me before ordering. Depending on the design, a custom size is often possible.

Step 4: Change your band

Remove the old band

1. Place your watch face down on a soft surface.
2. Press the band release button on the back.
3. Slide the band out sideways.

Attach the new band

1. Slide the new band in until you hear or feel a click.
2. Give it a gentle tug to make sure it is secure.
