what is the meaning of sweep second hand. how is it different?

Answer 1

Bad luck that you just got four idiots with the wrong answer.

Quite old watches had the seconds hand in a little dial of its own, about a quarter of the size of the main dial, positioned between the centre and the six o'clock point on the main dial. I don't think you can get them any more. When someone engineered how to have all three hands rotating round the centre, and indicating on the same big dial, it was thought to be a big advance, and they called it a "sweep second hand" because it sweeps round the whole dial insted of twirling in its own little dial.

It has nothing to do with how quickly the hand moves, or what kind of noise it makes, only with how long it is and what point it turns around.

Answer 2

sweep-sec·ond hand
n.
A long hand on a clock or watch that measures seconds by moving the space of a minute for each second. Also called sweep hand.

In a quartz watch the second hand is propelled forward by a pulse like a regulator clock in a school or train station. The second hand is ultralight nowadays (unlike a mechanical system with a second hand which "balances" part of the escapement inertia and which would wiggle incredibly if it was ultralight). Even at higher movement rates the second hand on a quartz mechanism wouldn't look like the second hand on a mechanical watch.

Answer 3

Sweep second had means is moves smoothly around the face as opposed to "ticks"--where the hand moves in small increments, a "click" or second each. Also, if you put your watch to your ear, you won't "hear" the sweep hand, bu will likely be able to hear the small ticks or clicks each time the second hand moves on a non-sweep hand watch.

Answer 4

sweep means the second hand it moving continuously as opposed to ticking along

Answer 5

SOme second hands click-click-click.

better watches offer a smoother function and makes for better timing
