Frequently Asked Questions

Find quick answers to the most common questions about our product.

A G-Shock Mod Watch starts as an authentic, brand-new Casio G-Shock and is hand-rebuilt with premium high quality parts — including full stainless steel cases, brushed metal straps, and custom dials. The result is a luxury-looking timepiece that retains all the toughness of the original G-Shock.

Yes, 100%. Every G-TUNE Mod starts with a genuine, brand-new Casio G-Shock purchased directly from official sources. We never use counterfeit or grey-market watches. Your mod comes with the original box and parts, papers, and warranty card.

Custom-configured watches typically take 4–8 business days to build before shipping, as each one is assembled by hand. You'll receive updates throughout the build process, and once your watch is finished, we'll send you a tracking number so you can follow your order. Shipping then takes 4–7 business days.

Yes. All G-TUNE Mod Watches keep the original Casio G-Shock international warranty, even though G-TUNE is not affiliated with Casio: we don't modify the movement, and the Casio warranty covers the movement, not the bezel or the strap. You also get our G-TUNE store warranty (2 years). Your package includes the original warranty card and documentation. To activate the warranty, you can send us the watch and we'll handle it — you'll just need to include the original band, watch, and box.
