Watches are essential for many people, fulfilling not only an important timekeeping function, but also playing a vital role as fashion accessory. Sometimes, however, they require upkeep, be it a battery replacement or a more intricate repair. While involved maintenance, particularly of antique and highly valuable watches, should be the domain of skilled professionals, it is possible to perform some repairs at home, with the right tools and know-how. When in doubt, consult a watchmaker.
