NEEDLE vs. HAND （コンパスなどの）針 vs.（時計の）針

The long, thin pointer on a compass (= a tool used to find direction) and many other measuring devices is called a needle.

Each of the (usually 2 or 3) pointers on a clock is called a hand.

Be Careful! We do NOT call a clock hand a needle like the Japanese 時計の針.
コンパス（方向を知るための計器）や、他の測定機に付いている細長い針のことを needle といいます。

時計の針（通常2本か3本）のことは、hand といいます。

注意：日本語では、時計の「針」と言いますが、英語では clock hand のことを日本語のように needle（針）とは呼びません。

The needle of a compass always points north.
POLICE OFFICER: Do you realize that you were driving 125 kilometers per hour?
DRIVER: I'm sorry, officer, but my speedometer needle is stuck (= won't move).
Most analog clocks have at least two hands: one to tell the hour and another to tell the minutes. These are called the “hour hand” and the “minute hand”.
Does your watch have a second hand?
