A well-cared for watch can last for many generations. Be sure to have it thoroughly checked every two years by a professional. There are though a few things you can do yourself to extend its lifespan. For example, try to avoid your watch coming into contact with water or abrasive substances that may scratch. Magnetic fields and direct sunlight can also damage the mechanism or battery. Ideally, polish the gold with a damp cloth and the leather watch strap with a soft cotton cloth. Have any damaged glass replaced by a specialist as soon as possible.
