Hacking movement

[ducksaw]

Can someone define hacking movement and let me know how to distinguish which models feature it?
Thanks

A hacking movement is one that allows you to stop the second hand by pulling the crown out to it's furthest point.

I believe all of the models have them now, but if I'm wrong, someone please correct me.

Hacking is a military term. As Paul stated it's a feature that allows you to freeze the seconds hand to sync the time with a known source.

The hacking feature started to come into the line in the early 70s.
Although many older references don't possess the hacking feature it is possible to "hack" many non-hacking watches by simply applying slight back pressure to the winding stem. This will stop the second hand. Sounds dangerous I know, but it has no adverse affect on the movement.
Not all watches will do this. I have one 1675 that I can hack in this manner and one that I can't.

A non-hacking non-quickset must not be fun to re-set when not kept wound

Great thread. I thought my 1675 didn't work correctly since it wouldn't stop with the stem out. Since reading this, I feel better about the 1675. Thanks all.

You are correct, Paulie!

The LAST Rolex watch to have a NON-hacking movement was the Daytona movt. Cal. 4030 ("Zenith" modified movt.)

So from year 2000 when Rolex introduced the new Daytona movt. Cal. 4130 featuring hacking seconds, all Rolex movts. have the hacking feature.

Why do you worry about that, Paulie? Your Sub never needs winding since it is battery powered, and also it has "hacking seconds" (in ONE second intervals, that is!)
