This is a collaboration between TIMEX and and wander. TIMEX is a watch brand founded in Connecticut, USA in 1854. This collaboration features a model from the sustainable outdoor line, EXPEDITION NORTH. The crystal is made of anti-reflective sapphire crystal for enhanced visibility, and the movement is solar-powered, storing power from sunlight. The strap is made of upcycled materials, reducing environmental impact. Once fully charged in sunlight or other light sources (approximately 4-5 hours), the solar-powered watch will operate for approximately 4 months in the dark. It is water resistant to 10 ATM. Case: Stainless steel; Crystal: Sapphire crystal; Strap: Nylon *Products with solar movements may not function upon arrival; this is not a malfunction. Charge the watch under a light source before use and it will function normally.
