Automatic Watches (without Battery)

General Warnings
Sensitivity to magnetic fields: Automatic watches are susceptible to magnetic fields (e.g., from speakers, magnetic clasps, or electronic devices), which can affect their accuracy. Keep the watch away from strong magnetic fields.
Check water resistance: Automatic watches are not always fully waterproof. Check the specified water resistance rating (e.g., 3 ATM, 5 ATM) and avoid water exposure unless the watch is specifically designed for it.
Regular maintenance: To ensure the precision of the watch, it should be serviced by a professional every 3–5 years.
Winding the watch: Automatic watches require regular movement to remain operational. If the watch is not worn, it can be manually wound carefully. Do not overwind the crown, as this may damage the mechanism.

Material and Care Instructions
Handle with care: Mechanical movements are sensitive to shocks. Avoid hard impacts or drops to prevent damage.
Sensitivity to chemicals: Contact with chemicals such as perfumes, cleaning agents, or cosmetics can damage the case, seals, or strap.
Cleaning: Clean the watch regularly with a soft, slightly damp cloth. Avoid using aggressive cleaning agents.

Health Warnings
Allergies: Certain materials (e.g., stainless steel, leather straps) may cause skin irritation or allergic reactions in sensitive individuals.
Weight of the watch: Automatic watches can be heavier than quartz watches due to the mechanism. Avoid wearing the watch too tightly to prevent pressure marks.

Quartz Watches (with Battery)

General Warnings
Battery replacement: Do not attempt to remove or replace the battery yourself. Contact an authorized service center to avoid damaging the watch.
Caution with leaking batteries: If a battery leaks, it can damage the watch mechanism. Replace empty batteries promptly.
Not rechargeable: The batteries used in quartz watches are not rechargeable. Do not attempt to recharge the battery, as this can lead to overheating or explosion.
Check water resistance: As with automatic watches, water resistance is important. Battery replacements may affect the seals. Have the water resistance rechecked after a battery change.

Material and Care Instructions
Sensitivity to heat and moisture: High temperatures or extreme humidity can damage the watch's electronics. Avoid prolonged exposure to direct sunlight or humid environments.
Avoid chemicals: Keep the watch away from aggressive substances such as perfumes, cleaning agents, or lotions to prevent damage to the case or strap.
Cleaning: Wipe the watch with a soft cloth and avoid water unless the watch is waterproof.

Health Warnings
Allergies: Certain materials (e.g., leather straps, plastic, or metal cases) may cause skin irritation. Choose hypoallergenic materials if you are known to be sensitive.
Caution with battery ingestion: Button cells in quartz watches pose a risk if swallowed. Keep the watch and spare batteries out of reach of children.
