Tissot Seastar 1000 Chronograph Watch T120.417A

Got about 3 years ago.  Worn casually, never dropped or mishandled.  Put a new battery in about 6 months ago.  There are some scratches on the bottom half of the band from normal use typing on a computer for work and resting my hand on the desk.   New these are about $595.00 I believe now.   I paid $500.00
