BEFORE YOU ORDER
Questions we get daily
Does modding void the Casio warranty?
Yes — opening the case ends Casio's coverage. That is why we replace it with our own 12-month warranty covering assembly, sealing and finish on every part we touch.
Is it still water resistant after the mod?
Every build gets new gaskets and a 20 bar pressure test before it ships. Swimming and showering are fine; we still ask you to skip the sauna.
Can I send in my own GA-2100?
Yes. Choose the send-in option at checkout and we deduct the donor watch from the price. We inspect it first and tell you if the module needs work.
How long does a build take?
Ten to fourteen days for standard configurations. Hand-painted dials take fourteen to twenty-one days because each layer has to cure.
Do you ship outside Indonesia?
We ship tracked and insured to more than sixty countries in three to seven working days. Import duties are shown at checkout before you pay.
Drop alerts, no noise
