Cleaning watches ultrasonically: what to check first
Ultrasonic cleaning works well on watch cases, bracelets and clasps, but the water resistance rating matters before you start: a watch rated for daily wear (30m/3ATM or higher) generally tolerates the light vibration and brief water exposure of a cleaning cycle without issue, while vintage or unrated watches carry more risk of moisture working past aging seals. A dedicated watch stand, like the one included here, keeps the case elevated and stable during the cycle rather than resting directly on the tank floor, which is the detail most generic jewellery cleaners overlook.
