First, I'm not so sure you got good advice from the person you spoke to about repairing the B&M. A quote for $2K doesn't sound right at all to me! But leaving that aside, the oil in a watch does naturally breaks down over time. The owners manuals should indicate so and recommend a suggested service interval (usually every ~3-5 years). This 'servicing' is normal, required maintenance, and it will include cleaning the movement and replacing the oils with fresh lube. Depending on watch brand, movement type, & watch maker, service costs are typically between $100 - $600. You should be able to have a common ETA movement serviced by a competent, local watchmaker for less than $150. BTW, service intervals are somewhat controversial among watch nerds. Some just wait till their watch starts running slow or erratically before bothering with it. However, if I were you, I'd spend a couple of weeks researching this on the Internet and then seriously consider having your Omega serviced in the near future. Or, you could buy a Seiko (grin). Stories of 20 year old Seikos that have never been serviced are pretty common.
