Don't just assume your 200-meter+ Rolex is ready for a dive without an AD's seal of approval. Always check the seller's credentials, as you don't want a 'Franken-watch' or surprise service bills later. It's not just about water resistance; it's about the integrity of the piece.
As of the latest market analysis, the premium for high-end Rolex models, such as the ceramic Daytona and GMT-Master II, continues to fluctuate but is showing signs of stabilizing. The current market price, which often reflects a significant discount from the Manufacturer's Suggested Retail Price (MSRP), indicates a slight cooling down in the premium for these sought-after pieces. This trend could be attributed to a more balanced supply-demand dynamics and increased availability through authorized dealers. However, it is important to monitor the market closely, as fluctuations can occur due to various factors, including seasonal demand and collector interest.
