Keep it clean and dry
Wipe the case and bracelet with a soft microfiber cloth after wear. If the watch is water resistant and the crown is secured, occasional gentle cleaning can help remove sweat and dust.
Respect magnetism
A magnetized movement can run fast or irregularly. Keep mechanical watches away from speakers, magnetic clasps, and strong electronics when possible.
For long-term accuracy, schedule professional service according to the brand's recommended interval or whenever performance changes noticeably.
