The manual included is VERY brief, and does not include any instructions except how to set the time and auto-wind.  No directions for how to size the band are given, and trying to find the information on Stuhrling's website are nearly impossible, as the product number is not listed on any of the paperwork included in the packing material.  It would be much easier if they included the simple instruction 'resizing of band should be done by a jeweler.
