The Breitling Watch Source Forums

I was wondering how Breitling would still be able to maintain certain movements if parts became restricted. I’m not so concerned about ETA and Valjoux movements, because these were mainstays of Breitling’s lineup and they probably have stockpiles of parts. These movements were also so prolific in the Swiss watch industry that it seems parts could be obtained from other venders if it became necessary. My concern is mostly with movements that weren’t very common but have now become restricted, i.e. the Lemania 1877.

It's really not an issue.

Movements that have been obsolete for 60+ years still have parts available, movements that have been obsolete for 100+ years are still maintained through the ability to make or source parts. Mechanical watches will be capable of being maintained for centuries regardless of attempts to restrict supply.
