The Rolex Deepsea Sea-Dweller with reference number 136660, released in 2023, represents the pinnacle of Rolex's diving watch technology. With a striking 44mm stainless steel case diameter, it is designed for extreme deep-sea diving and offers a robust and powerful presence on the wrist. The combination of a solid case and the characteristic ringlock construction gives the watch its exceptional resistance to extreme pressure. The black dial is simple, functional and easy to read, with large, luminous hour markers and hands that guarantee optimal visibility even in dark environments. A striking detail is the date display at the 3 o'clock position, which is equipped with a cyclops lens to enable clear and quick reading. Another technical highlight of this watch is the helium valve, which makes the Deepsea Sea-Dweller especially suitable for saturation dives. It regulates the pressure during the ascent and reliably protects the movement. Inside beats the high-precision caliber 3235, an in-house movement from Rolex that is not only known for its precision and power reserve of around 70 hours, but also for its extreme reliability and resistance to magnetic influences. The stainless steel Oyster bracelet is fitted with a secure Oysterlock clasp and the innovative Glidelock system, which allows fine adjustment of the bracelet length without tools to ensure a perfect fit over diving suits or on the wrist. The Rolex Deepsea Sea-Dweller 136660 combines innovative technology and robust design to withstand the challenges of the deep sea, while still remaining a stylish watch for everyday wear.
