Thanks guys, I'm new to this so it was a bit confusing, but i think you have answered my questions. It does seem that the watch has gone through tough times, but it's still going strong in ticking!
Another question, do you know about how much it costs to have it professionally restored it to it's previous glory?
I might be leaving Sweden after living here for 3years and i think a Surevan would be a great departing gift. I'm wondering if it's worth the cost though ( the watch itself is about 200E).
