When choosing a watch, many buyers only focus on appearance and brand, ignoring the core technical knowledge behind timepieces. A watch’s durability, time‑keeping accuracy and collection value are determined by its internal movement, structural design and material craftsmanship.

This article sorts out basic watch knowledge, compares three mainstream movement types, explains core movement parameters, common watch materials, water‑resistance standards and daily maintenance skills.

The movement is the heart of a watch, deciding power source, precision, service life and wearing experience. The mainstream watch movements on the market fall into three categories: mechanical movement, quartz movement and solar movement.

Mechanical watches run purely by mechanical energy without batteries. Power comes from the energy stored inside the mainspring. It divides into manual‑winding and automatic‑winding versions.

Manual‑winding mechanical watches need regular crown winding to store spring energy.

Automatic mechanical watches rely on the oscillating rotor. Arm swing during daily wear drives the rotor to wind the spring automatically. Frequent manual winding is not required for daily use.

Mechanical watches attract collectors with delicate hand‑crafted mechanics. Hundreds of tiny gears, balance wheels and springs cooperate precisely.

Shortcomings also exist. Influenced by gravity, temperature and impact, time deviation is unavoidable. Daily error within ±15‑30 seconds counts as normal. Periodic professional maintenance is required.

Quartz watch represents practical‑oriented timepieces. Powered by battery, the quartz crystal vibrates at a fixed high frequency. The chip converts vibration signals to drive watch hands.

Compared with mechanical watches, quartz watches deliver outstanding time accuracy. Monthly error is only several seconds. It is barely affected by external environment.

There is no complex mechanical transmission structure. You only need battery replacement every few years.

Disadvantages lie in weak craft‑collection value. Quartz watches focus on high cost‑performance and practical experience.

Solar watch is an upgraded variant of quartz movement, belonging to eco‑friendly intelligent movement.

Built‑in photosensitive components under dial absorb natural light or artificial light, convert light energy into electric power and store inside special rechargeable cell to supply watch operation.

Fully‑charged solar watch can keep running over 6 months in total dark environment. It avoids frequent battery replacement, balancing accuracy, convenience and environmental‑friendly performance. Solar watches are great choices for daily‑worn timepieces.

When evaluating watch quality, do not judge merely by appearance. Pay attention to three core parameters: vibration frequency, power reserve and craftsmanship.

Vibration frequency

Vibration frequency means oscillation times of balance wheel per hour. Common standards are 21600 vph and 28800 vph.

Higher vibration frequency brings stronger anti‑interference ability and stable time‑keeping performance. High‑end mechanical movements usually adopt 28800 vph. Meanwhile parts wear distributes evenly for better long‑term stability.

Power reserve

Power reserve stands for how long the watch can keep running after fully‑wound.

Basic mechanical movements offer around 40‑42 hours power reserve. Improved high‑end movements can reach 70‑80 hours or even longer. Long power reserve allows the watch to keep running even if you do not wear it for one or two days, improving practical experience greatly.

Movement finishing craftsmanship

Movement finishing is not only visual decoration. It reduces part friction, improves stability and extends movement service life.

Entry‑level movements often have plain finishing. Mid‑range movements apply basic fish‑scale polishing. High‑grade movements come with internal Geneva stripes, pearl grain polishing and precise chamfer decoration. These fine details are important signs to distinguish watch grades.

Common watch case materials include stainless steel, alloy, titanium and precious metal.

Stainless steel is the most widely‑used material, balancing hardness, anti‑corrosion and cost‑performance. Titanium case features light weight and skin‑friendly performance. Precious‑metal cases serve for high‑end collection‑grade watches.

Sapphire crystal is mainstream for mid‑high‑end watches. It owns high hardness and scratch‑resistant property. Mineral glass is mostly used on entry‑level watches with lower anti‑scratch performance.

Main strap types: metal bracelet, leather strap, silicone rubber strap and nylon strap.

Metal bracelet is durable for daily wear. Leather strap brings comfortable texture but needs protection against sweat and water. Silicone rubber strap suits sports‑style watches with waterproof property. Nylon strap is lightweight and cost‑effective.

Water‑resistance mark on watch does not mean the watch can be worn for bathing, sauna or hot spring.

Watch water‑resistance is tested under static cold‑water environment. High‑temperature steam will age and deform internal waterproof gaskets, resulting in damp and rust inside movement.

‑Avoid heavy impact and violent sports. Impact may shift precise internal movement parts.

‑Keep away from magnetic sources such as mobile phones, wireless chargers and speakers. Mechanical watches are easy to get magnetized and run fast.

‑Do not wear watches for bathing, sauna or hot spring.

‑Wipe case and strap regularly to remove sweat and dust, prevent long‑time corrosion.

‑Mechanical watches need full‑service oil‑washing maintenance every 3‑5 years. Replace aging waterproof gaskets meanwhile.

Understanding watch movement types, core parameters, material features and water‑resistance limits helps you pick suitable watches. Proper daily care can greatly extend your watch service life.
