Every watch built by hand

Hi, I'm Luke. I started JellyLab to make a great watch a little more personal.

I left a career in finance to mod Casios full time. Every JellyLab watch starts as a brand-new, genuine Casio, gets disassembled and rebuilt at my bench in Houston, and ships in a box I 3D-print a few feet away.
