This is my  second MTG900DA-8 G-Atomic Tough Solar Watch.  The first watch has been working for five years and no
problems until it stopped working.  I immediately ordered a new duplicate from Amazon since I had no watch and it was
not convient to see the time on my Cell Phone.
I took the new watch to a repairman to have links taken out of the band, I never thought about repairing the old watch,
considering the cost to repair.  The repairman put a new battery in the old watch for $10.00, it started working immediately and I
now have two great watches.
