Pardon my ignorance of watch lingo, but what is "hacking" and it is good,:D bad :( or indifferent :? ? Thanx...........
Hacking is the abilty to stop the seconds hand from moving. The ETA2824-2 movement, for example, "hacks". It is used for sttinng time to the precise second. Among others, the lower end Seiko auto movements are not designed to hack; neither are the Unitas handwind movements. Some movements that do not hack can have hacking simulated with a slight backward pressure on the winding stem. Here is an excerpt from a TZ post:
1.1.2 What is a "hack" seconds feature?
This, AFAIK, is a military term referring to watches that stop the second hand, to allow for more accurate synchronization between two watches. In the most common type of hacking watch, when the crown is pulled out to the time-setting position, a lever is moved which contacts the rim of the balance, thus causing the movement to stop. John Davis has seen other methods used to stop the movement as well, including brakes on the third or fourth wheel.
A. Lange & Sohne have produced a watch that stops the balance when the crown is pulled out and automatically moves the second hand to the "0" position - to help facilitate setting against an accurate time reference.
