sweep hand
Low (Specialist)Formal/Technical (Horology)
Definition
Meaning
The long, thin second hand on an analogue clock or watch that moves in a continuous sweeping motion, unlike a ticking hand.
Refers specifically to a hand on a chronograph or stopwatch that can measure elapsed time to fractions of a second, often moving in a smooth glide. More broadly, can denote any long, slender indicator that moves across a dial.
Linguistics
Semantic Notes
The term emphasizes the continuous, smooth motion (sweep) as opposed to the jerky, one-second-per-step motion of a standard second hand. It's almost exclusively used in contexts discussing timepieces, instruments, or gauges.
Dialectal Variation
British vs American Usage
Differences
Usage is identical and specialist in both varieties.
Connotations
Conveys precision, quality (in watches), and technical detail. Often associated with high-end or specialised timekeeping instruments.
Frequency
Equally low frequency in both dialects, confined to horology, engineering, and instrument design.

FAQ
Frequently Asked Questions
Not exactly. All sweep hands are second hands, but not all second hands are sweep hands. A 'sweep hand' specifically denotes a continuous, gliding motion, as opposed to a ticking motion.
No. The term is inherently analogue, referring to a physical pointer. A digital display might simulate the effect, but it is not a 'hand'.
In mechanical watches, it's caused by the watch's balance wheel oscillating at a high frequency (e.g., 28,800 beats per hour), dividing a second into many tiny steps that appear smooth. Quartz watches typically tick once per second.
Yes, 'sweep seconds hand' is a common and synonymous full phrasing, emphasising it is the seconds hand that sweeps.
