About this watch
The Rolex Sea-Dweller 16600 Comex MK2 is a masterpiece of luxury watchmaking, boasting an impressive array of technical specifications and design elements that make it a true gem. The watch's robust stainless steel case, polished and brushed to perfection, houses the iconic Mercedes hands and a glossy black dial adorned with luminescent stick and dot indexes. The rotating 0-60 dive scale on the bezel emphasizes its functionality as a professional diving watch. Powering this timepiece is the renowned Rolex Caliber 3135, an automatic movement certified by the Swiss Official Chronometer Testing Institute (COSC) for high precision. With a 48-hour power reserve and frequency of 28,800 vibrations per hour, this movement is a marvel of Swiss engineering. The watch's exceptional water resistance of 1220 meters makes it perfect for deep-sea diving, while its sapphire crystal scratch-resistance ensures durability in harsh conditions. This collector's piece is not only a testament to Rolex's dedication to quality and innovation but also a highly sought-after investment opportunity due to its limited production runs and association with the esteemed COMEX diving company.
