i have a number of watches but my most everyday work favourite is my seamaster. I'm not a deep sea diver, or someone who inflicts any sort of stress on my lovely watch, I just commute to London and back. I went to get a new battery fitted by Goldsmiths as I do every 2-3 years and it's where I bought the watch many years ago. Today I am told it'll be £320 as it needs a service and the battery may have leaked again (told me this last time). They tell me this every time but I can't see how it's getting dirty or why they persist in using inferior batteries. I also keep my watch in a watch case when it's not in use along with my others and even pull out the bezel as advised so the battery doesn't deplete. I suppose I am asking if anyone knows why these omega watches seem to be prone to collecting dirt and have poor batteries and lastly why so expensive.
