Omega Seamaster 300 M loose parts?
I bought a second hand 2005 Seamaster 300M from a reputable dealer in December. I only wear it some evenings and weekends, and always take it of when getting 'active'. It never even got wet.
Since this week, without anything happening, it started rattling. Sounds like there is a part loose inside the watch. Does this happen more often, is it normal or is this watch that was sold to me as Like New Condition not good to begin with? I am worried that it might get very costly to repair.
Any idea what's the problem, and what I should expect from the jeweller I bought it from?
Thanks in advance,
