Rolex recommends servicing their watches approximately every ten years, but this can vary based on several factors including the specific model, usage, and individual wear patterns. Regular servicing is essential to maintain the watch's precision, performance, and waterproofness. Over time, oils within the movement can break down, which can affect accuracy and longevity. Additionally, factors such as exposure to water, temperature changes, and daily wear can influence the service interval. It is beneficial to pay attention to how the watch is performing; if there are any signs of difficulties such as inconsistent timekeeping or unusual sounds, it may be advisable to consider servicing sooner.
