How often are reversers replaced?

[vintagewaferthin]

Was just wondering if replacing the reverser gears, or one of them is common during a overhaul? Im bringing in my 1980 5500 for a overhaul next week, and I was wondering if this would end up being done. I say that because when I bought the watch originally, I noticed that two of the reversers were missing their jewels. Im sure this caused a bunch of wear, no? Also, if one is replaced, do they all have to go?

They're usually replaced in pairs. The reversers are of course parts that see a lot of wear when a watch gets worn often, because they are part of the automatic winding system, that is why they can need frequent replacement during routine service.

Ok, figured as much. I remember looking at the movement pics when I bought it and it looked as if two of the reversers were missing jewels, but after reading up it appears that this is normal? RSC NY made no mention of this, so I'm assuming it is as it should be.

The reversers themselves don't have jewels (unlike many ETA movements) but they each rotate between two jewels in the upper and lower automatic bridge.

As with the majority of parts for this or any other caliber, regular maintenance will extend the Reverser Wheel life expectancy.

Interestingly, there is a percentage of "rough winding" wheels that can be brought back into proper function after a de-magnification. Although the percentage is less than 30%, there's merit to include this check in an evaluation.
