Maintaining a ETA 2892.A2

[j***@netzero.net]

I have a Xemex Avenue with a ETA 2892.A2 movement. It is almost 4
years old. Seems to function just fine. Time to overhaul or wait for
some indication...change in accuracy... before overhauling it? Does how
often I wear the watch enter into the calculation of frequency of
overhaul?

Typical service interval recommendation for modern watches is 5 years, but
if the watch is still running strongly you might get away with more. Need
for service depends partly on age of lubricants, but a watch that is worn
constantly will collect more dirt and have more wear, so will need service
sooner. It is a bit like a car, in that you can delay the service interval
without immediate consequences at the price of decreasing the overall life
of the product - even if the watch continues to run , invisible wear will
accelerate if the watch is beyond it's service interval so you'll end up
paying at the end. OTOH, something like a Seiko 5 you can just wear until it
no longer runs well and then toss - some people get 20 years without service
this way.

Jack. Thank you! As always, your intelligent informed responses are a
great help.

The 2892 is said to have a lot of spare torque to allow for the addition
of complications. If the watch is a daily wear watch and highly prized
it might do with some oil at 7-8 years otherwise just wear it. How is it
performing timekeeping-wise?

Don't forget those pesky reversing wheels. They are expensive to
replace and if left to gather junk, it'll happen much sooner.
