Yes they're like any other spring bar and can fail, I always charge for them when I make a full service price estimate but I know that not every watchmaker does this. Over here they're €80 for the two including tax.

How long they last depends on several factors, most of which you already stated, keeping the watch clean is also quite important because often the dirt will mess with the spring bar over the years. Personally I would change them every service if it was my own watch.

Thank you Bas and all for the input and advice.
