Key information for overseas buyers, retail distributors, and procurement partners.
Yes. All Cosmo replacement watch bands utilize a precision-engineered 18mm quick-release pin system. They fit seamlessly across all JrTrack hardware generations including JrTrack 2, JrTrack 3, JrTrack 4, and the flagship JrTrack 5 SE.
Because our wearables are designed specifically for children aged 6–12, safety is paramount. All band materials undergo rigorous chemical and mechanical testing. They are non-toxic, hypoallergenic, BPA-free, and fully compliant with international REACH, RoHS, and CPSIA requirements.
We provide full OEM/ODM manufacturing capabilities for qualified distributor partners. This includes custom Pantone color matching for silicone molding and textile weaving, branded laser-etched buckles, and custom retail packaging solutions.
The integrated quick-release spring bars allow tool-free installation in seconds. Users simply slide the quick-release lever inward to attach or detach the band from the watch casing without needing specialized jewelry tools.
