Samsung Gear Fit2 Pro fitness tracker, black with large band. Comes with original box, invoice and accessories. Screen has two small chips on it (see picture 3), however these do not affect the usability. Band is worn on the bottom, this is expected for age. New bands are available online. Battery still lasts a day, however may need charge after workout if using GPS.

edit: band broke at one side, new small size band will be included.
