One of the reasons I appreciate mechanical watches is because they are (reputedly) more easily repaired in the long-term than are quartz movements. I like the idea of being able to fix my watch when it breaks down in 15 years, instead of having to junk it because a board (as in a quartz movement) isn't being made any more. Here are my questions:
How do ETA and Sellita compare in terms of availability of parts to whoever would be fixing my watch? How do they compare in terms of availability of complete movements to whoever would be fixing my watch?
You could easily list the answers to this in a Punnet square: ETA parts availability, Sellita parts availability, ETA movement availability, Sellita movement availability.
My goal in asking these questions is to get a sense of which company's movements might best stand the test of time via repair and replacement, etc.-to me, these things define a sustainable watch. Everything wears down over time-I want to know what is most likely to be able to be fixed.
