Even though the watch is designed to be waterproof, it is not completely airtight, and tiny particles of dust can still find their way inside. Additionally, over time, the seals and gaskets that keep the watch waterproof can degrade, allowing dust to enter. Finally, when the watch is opened for battery replacement or maintenance, dust can also enter if not properly sealed afterwards. **
