The Bradley wasn’t the first watch design we came up with.

By collaborating with people in the blind community, we learned that we had misconceptions about what people with vision impairments want in a watch. We also underestimated the impact of including marginalized people in the design process — how diverse experiences push us to create better products that more people can use.

Listen to our founder, Hyungsoo Kim, explain how we designed a watch for everyone, sighted and blindthe Bradley timepiece.
