Pulled crown out, watch didn't hack
 

Had a weird one tonight: Pulled the crown of a time-only watch out to its second position (or is ti first?), felt it actually pull out, but then the watch didn't hack. Pushed it back in and tried again, and it did as it was supposed to. Is it possible it just wasn't fully engaged the first time? Or did I have some gear or something slip?

What Watch?
Was it hacking before today?

Such Watch with ETA have some models without a hacking movement.

It happens.
Sometimes things don't quite engage as intended as it's such a fine line inside these tiny things.
I've had that exact same thing as well as other silly little things happen from time to time and all is well with my watches as far as I can tell.

Yea, it's a modern Rolex three-hander. Seems to be a one-off thing.

Thanks. For a moment was worried that I'd managed to create a problem, unrelated to the problem, on a 32xx :cheers:.

Probably extended the crown far enough to engage the intermediate setting wheels, but not far enough to have the balance stopper hit the balance wheel. It happens sometimes.

It's not super common, usually a change of one of the parts (setting lever, setting lever jumper, intermediate setting wheels, minute wheel, stem, balance stop spring) can be enough to never have it happen again.

All parts are manufactured with a tolerance, some spings or gears might be a couple of microns thicker, and some are nicer finished than others when compared to different manufacturing years, etc. Sometimes you get a parts combination and have a glitch like this happen. It's not harmful.

Another example of something similar is when you have a 3185/86 GMT movement (happens on the 3135 as well but much much less common), that when you pull out the crown to the setting position it won't let you, like something is blocking, then after winding and/or quick setting the hour it pulls out to the second position just fine.
What happens is that the 3135-250 intermetiate setting wheels that are in all of the variations of the 31×× series, hit each other teeth on teeth, blocking pulling it out to the setting position.

Thanks for that. Sounds like a "pulled it out, just not all the way" situation? Not that on a relatively new Rolex 3230 that alone would indicate a need to have a part replaced because something is off? Or that's only if it happens repeatedly?

Single instance should be chalked up to a shrug of the shoulders and "meh, happens sometimes" then forget it and move on?

For what it's worth, I didn't attempt to set the watch (just pushed crown back in and pulled again) so I have no idea what was/wasn't engaged.

Great explanation.
Many thanks:thumbsup:

It can definitely happen again, but it is not something to worry about:thumbsup: If you don't force anything it will not do any harm in the movement.

Agree!

Much appreciated :cheers:
