I think you've been lucky! The warning signs will come when the battery replacement is required (flashing end-of-life indication) sooner than expected - e.g. the new battery only lasting for 12 months or less...
Unless the 'local jewellers' is an authorised Breitling dealer, it's risking rather a lot to let him loose on your watch, in my view. A colleague tried that, no pressure or power soak test was conducted, so when his watch failed after immersion in shallow water, it was endex.
Of course some 'local jewellers' might be capable of meeting the Breitling battery change requirements, but not all would be. A local jeweller here in British West Oxfordshire lost Breitling accreditation after customer complaints.
Careful what you pay for!
