Frequently Asked Technical Questions
What quality standards and pressure testing procedures do Maxima waterproof watches undergo?
Every timepiece in Maxima's Waterproof Collection undergoes a double pressure testing regime compliant with ISO 22810 standards. First, a dry vacuum and over-pressure test confirms initial gasket compression and case integrity. Second, a post-assembly wet immersion condensation check ensures zero moisture ingress before final packaging.
What materials are used to ensure long-term water resistance?
We utilize surgical-grade 316L stainless steel, high-density aqua-fiber polymer composites, synthetic sapphire or hardened mineral crystals, and high-grade Viton/Nitrile synthetic rubber O-ring gaskets resistant to saltwater, sweat, and UV exposure.
Does Maxima offer OEM/ODM manufacturing and private labeling for international buyers?
Yes. As a vertically integrated watch house with six decades of manufacturing experience, Maxima provides complete OEM/ODM solutions, custom dial branding, bespoke case finishes, tailored packaging, and flexible B2B order volumes for global importers and retail chains.
What is the warranty coverage for wholesale waterproof timepieces?
