Titanium Band Size Guide

Not Sure What Band Size to Pick? Let’s Make It Easy.

We’ll help you find the perfect match in seconds.


👇 STEP 1: Find Your Watch Model

What Apple Watch Do You Own?

  • Apple Watch Ultra / Ultra 2 (49mm)

  • Series 1–10 & SE: These watches generally come in two sizes: large and small.

We show these sizes on the website as: 44mm / 45mm / 46mm for the large and 40mm / 41mm / 42mm for the small watches. Apple changes the mm size almost every year, but the same bands fit all generations. 

Example: Series 10 comes in 46mm and 42mm. Series 9 comes in 45mm and 41mm.

If you're not sure, please look at the back of your watch and find the size as shown below:


👇 STEP 2: Measure your wrist

Our titanium bands are a one-size-fits-most fitting up to 9" wrist circumference. If you have a very large wrist size, we recommend to add a pair of extension links to your order.

How to measure your wrist:


Use a tape measure or a piece of paper to measure just above the wrist bone (where your watch sits).
