 | There are some very good reasons why. First, the oil that keeps your watch running smoothly (and is just as important to it as oil is to your car's engine) will break down over time. Unlubricated watch parts can be abraded by friction. The problem can get even worse. Friction can create a fine dust that will in itself act as an abrasive. Additionally watches "breathe" -they expand and contract in response to hot and cold, allowing dust-carrying air to enter the case through microscopially fine cracks. This is true even of water-resistant watches, whose case-back and crown openings are protected by gaskets, which if not periodically replaced lose their effectiveness. This lack of lubrication combined with the entrance of airborne soil greatly increases the premature wearing of parts which can be quite costly to replace. This insidious process isn't evident until something goes wrong. |
