I know it's recommended that you service a Breitling every 3-5 years.
My Super Avenger is almost 4 years old but still running between -4/+4 or -5/+5 secs per day.
Is it only really necessary to service the watch when it runs out of COSC, or will the watch need new parts/lubrication?
Also, I recently polished the bezel to a mirror finish;

When I send my watch to Breitling, will they re-brush the bezel for me?
If this is the case, I'd prefer to send it without the bezel as I don't really fancy having to spend a couple of hours having to cape cod the bezel again after a service,
