Package contents (Greek market) - what is included / not included
- Included: 1x Apple Watch Ultra 3 (MEWM4QF/A) with Alpine Loop (Medium), USB-C to Magnetic Fast Charger, instructions/warranty booklets.
- Not included: separate wall charger with USB-C port (Modern Apple practice - reduces e-waste). Absence of charger follows e-waste reduction schemes and packaging options of manufacturers and distributors.
We recommend using a 20W+ USB-C certified PD charger for fast charging and optimal user experience.
Battery, charging and energy behaviour
- Rated autonomy: up to ~42 hours in normal use and up to ~72 hours in low-power mode/extended duration mode, depending on GPS and cellular usage settings.
- Fast charging with USB-C magnetic charger; recommended 20W+ charger power for faster crew.
- Energy consumption: depends on GPS, cellular and sensor usage; more demanding functions (GPS tracking, cellular streaming) increase consumption significantly.
Guidelines for optimal battery life: avoid constant high-power GPS streaming, enable power-save mode for sustained activities and charge between 20-80% for battery longevity.
Warranty, DOA, returns and business conditions
- Normal consumer warranty: 2 years where local law applies; many resellers offer additional after-sales or extended warranty services for B2B customers.
- DOA/RMA: standard DOA deadline 14 days for immediate replacement.
- Process: RMA registration, priority to B2B orders, local service centres for repairs and certified parts replacement.
Repair/turnaround time: usually 2-5 working days at official service centers, depending on availability of spare parts and local support.
