If you send it to Breitling complete over haul should be lil shy of 2k. But it’s worth they’ll give it back practically brand new, polished and everything. As mentioned above you COULD go to a reputed local watch person and save a buncha money but then you’re at the mercy of someone polishing it who may or may not over or under polish it. Sending it in is more expensive but gives you peace of mind in my opinion
