What to know before buying

Listing details to confirm

Battery duration is use-dependent: the feature claim gives up to 21 days in light usage and 14 days in normal usage, while the details table lists 21 days without a mode. The 46mm title conflicts with dimensions of 28 x 7 x 3.5 centimetres, and the listed 0.03 Kilograms weight and 64 MB RAM may warrant confirmation. The listing also calls the watch waterproof while separately giving 50 Metres and 5ATM ratings. Check these inconsistent or unconfirmed listing details before purchase.
