Longevity of a vintage speedmaster
I’m wanting to purchase a 1970s omega speedmaster. It’s a decent price and the I like the sellers. I would use this as a casual watch. I was wondering if servicing will become more difficult and expensive. Also I plan on keeping forever hopeful. How are these things built. Will it last another 50 years. Also how much should I wind it. I’m aware the bracelet is not original.
