One-Year Limited Warranty
One-Year Limited Warranty
Warranty Coverage
The90 warrants the Gem, Pendant, and Charger against manufacturing defects in materials and workmanship for one year from the date of original purchase. If a hardware defect arises, The90 will, at its discretion, repair the device or replace it with a functional equivalent.
Warranty Exclusions
This Limited Warranty does not cover:
Accidental Damage: Cracks to the Quartz Glass or metal gouges caused by drops, impact, or misuse.
Environmental Abuse: Damage resulting from submerging the Gem or exposing it to high-pressure water (e.g., diving, water skiing) or extreme heat (e.g., saunas, steam rooms, or hot tubs).
Battery Neglect: Failure caused by "Deep Discharge"—leaving the device at 0% charge for more than 7 consecutive days.
Unauthorized Service: Damage resulting from attempted repairs or modifications by any party other than The90.
Normal Wear: Subtle cosmetic changes to metal finishes or chains over time.
Device Care & Maintenance Guide
Sensor Integrity & Quartz Care
The90 Gem features a precision Quartz Glass face to provide accurate "Skin Intelligence" data.
Clarity: Keep the sensor window clear of thick sunscreens, heavy lotions, or oils. We recommend wiping the face daily with a soft, lint-free cloth.
Handling: Avoid applying excessive direct pressure to the Quartz Glass face to prevent stress fractures.
Water & Temperature Guidelines
Daily Exposure: Your Gem is designed for a life in motion and is safe for rain, showering, and splashing from pools or the ocean.
Post-Swim: Always rinse the Gem with fresh water after exposure to salt or chlorine to prevent mineral buildup.
Thermal Awareness: Metal and glass naturally absorb heat in direct sunlight. If your Gem feels uncomfortably warm against your skin, move to a shaded area or tuck the pendant under a garment for a few minutes.
Battery Health Protocol
To maximize the lifespan of your internal battery:
To prevent permanent battery degradation, do not allow your Gem to sit at 0% charge for more than 1 day.
Low Power Alerts: We recommend docking your Gem as soon as you receive a notification from The90 App.
Storage: If you are not wearing your Gem for an extended period, store it with at least a 50% charge.
