No, JellyLab is not associated with Casio. JellyLab is an independent watch modification service that customizes authentic Casio watches, but is not associated with Casio.

Yes! Luke is the owner of JellyLab and completes the majority of watch mods himself.

Yes, this website ships to the following regions:

• United States
• Canada
• United Kingdom
• European Union
• Switzerland
• Japan
• Hong Kong
• Australia
• New Zealand

If you are ordering from a region not listed, we can still fulfill your order via our Etsy store linked here.

I currently only offer the models:

• Casio Royale (AE1200)
• Caso F91-W

I plan on expanding this in the near future.

JellyLab only modifies new watches. This ensure consistent quality and avoids personal watches potentially getting lost in transit. Prices include a brand new base watch.

Yes, any internal modification occurs between the "glass" of the watch and the time module. This allows the watch to maintain its factory water resistance, even after modification. See my video here for a demonstration.

No, modifying the watch voids the factory warranty.
