EON “SpringTimer” Mod – Custom LF20W Beige Casio with Multicolor Screen & Oil Fill – Twin Graph-Inspired Digital Watch

Introducing the EON “SpringTimer” — our bold, colorful tribute to the newly released Casio LF20W.

This is one of the first known customizations of this model, and we wanted to mark it with a fresh and vibrant aesthetic. Inspired by the arrival of spring, we installed a custom-made multicolor screen filter inside the case and sealed it with premium silicone oil (hydromod), enhancing the contrast and pushing water resistance to 100m+.

It’s a true evolution of the classic Twin Graph platform: thinner, sleeker, and packed with functions. This is one of the most compact and capable digital mods we’ve ever done — and we’re proud to debut it here.
