If you've picked up an analog watch—or inherited one—and aren't sure how to read it or maintain it, you're not alone. Analog watches look straightforward, but the mechanics and best practices behind them deserve a clear explanation. This guide walks through how they work, how to read the time, and what keeps them running well.
An analog watch has three moving hands, each serving a specific purpose:
The hour hand (shorter, thicker) points to the hour. It moves slowly, completing one full rotation every 12 hours.
The minute hand (longer, thinner) points to the minutes. It moves faster, completing one full rotation every 60 minutes.
The second hand (thin, often a contrasting color) tracks seconds. Not all analog watches have one, but when present, it completes a full rotation every 60 seconds.
The dial (face) is divided into 12 numbers. Between each number are four smaller tick marks, representing the individual minutes in that five-minute block.
Reading an analog watch takes just three steps:
Find the hour. Look at where the hour hand (the short one) points. If it's between 3 and 4, the hour is 3.
Find the minutes. Look at where the minute hand (the long one) points. Each number represents five minutes: the 1 is 5 minutes, the 2 is 10 minutes, the 3 is 15 minutes, and so on. Count the small tick marks between numbers for the exact minute.
Check the seconds (if your watch has a second hand). The second hand uses the same dial—each number represents five seconds, and tick marks fill in between.
Example: If the hour hand points between 2 and 3, the minute hand points to the 4, and the second hand points to 6, the time is 2:20:30.
The accuracy and reliability of an analog watch depends on several factors:
Movement type plays the biggest role. A quartz movement (battery-powered) keeps very consistent time, typically losing or gaining only a few seconds per month. A mechanical movement (powered by a spring that you wind) or automatic movement (wound by your wrist motion) is less precise and may lose or gain 10–30 seconds per day, depending on the watch and how well it's maintained.
Age and condition matter significantly. Older watches or those that haven't been serviced in years may drift more noticeably. Dust, moisture, or wear inside the mechanism can affect timekeeping.
How you wear it influences automatic watches. If you don't wear an automatic watch regularly, it may lose power and stop. Mechanical watches require regular winding to stay accurate.
Environmental factors like temperature, magnetism, and shock can temporarily affect accuracy in any watch.
Quartz watches run on a battery, so maintenance is minimal. Replace the battery when it stops keeping time (typically every 2–3 years, though this varies). You should not wind a quartz watch—there's nothing to wind.
Manual mechanical watches need to be wound regularly—usually daily or every other day. Turn the crown (the knob on the side) clockwise about 20–30 rotations until you feel slight resistance. Don't force it. This winds the mainspring, which powers the watch.
Automatic watches wind themselves through your wrist motion as you wear them. If you wear the watch regularly (ideally 8+ hours a day), it should stay wound. If you stop wearing it for more than a day or two, it will gradually lose power and stop. You can hand-wind it using the crown by turning it clockwise if needed to restart it.
If your analog watch stops, loses time rapidly, or the hands are sticking or moving erratically, a watch repair professional can diagnose the issue. Common repairs include battery replacement, movement cleaning, seal replacement, or hand adjustment.
The right choice about repair versus replacement depends on the watch's age, sentimental value, and repair costs compared to purchasing a new one—factors only you can weigh.
