Dumb question, probably a FAQ: If these watches are so well sealed that they can handle a depth of 2000 meters, why would they need lube? Where did the lube go? How can it escape? |

Much like an automobile, I would venture to say that the viscosity of the lube changes over time...possibly causing the movement to "gunk" up. regards, Mark(msa6712) |

There are two main issues that need to be addressed by servicing. First off, the oils in the watch (there are at least two different types usually) do break down over time as has been suggested. They tend to thicken and lose their ability to lubricate effectively. I'm not a chemical engineer and can't explain to you what is happening at a molecular level, but that's the symptoms. Secondly, pieces wear out. These movements are not wear free and over the years pieces will need to be replaced. Remember that the balance wheel is vibrating a 28,800 vph - that's over 1.25 billion (with a b) vibrations in a 5 year maintenance cycle. The escape wheel is being stopped by the pallet fork over 600 million times - you get the idea. Not all of these parts are automatically replaced, but they do need inspection on a regular basis, and much like in a car, preventive maintenance is a lot easier (and cheaper) than dealing with the consequences of failure. |

Good question and excellent answer by Roffensian. I think it is better to call it a "service" rather than a "cleaning", which always made me wonder the same question. Michael |

Service is recommended every 5 years, but the simple answer is when it can no longer keep accurate time. The only exception would be if you dive regularly, especially in salt water when the seals should be checked and replaced every 12 months or so. A full service is generally $400 - $500 or so. |

I don't know are those real prices or estimates but it's somekind of info at least. http://www.breitling.com/en/maintenance/ |

After looking at that pdf, how often would you get a complete overhaul compared to regular maintenance? |

The regular maintenance is more useful if you need the seals changed, or if the watch needs significant regulation (i.e. beyond the adjustment that can be achieved via the index). The danger with trying to fix problems with regular maintenance is that the problem may not be in the escapement, and therefore this won't fix it. |
