rolex deep sea dial blu | Rolex deepsea blue for sale

The Rolex Deep Sea Dial Blu, more specifically referring to models like the Ref. 136668LB, represents the pinnacle of Rolex's engineering prowess and commitment to pushing the boundaries of underwater exploration. More than just a timepiece, it's a statement piece, a symbol of adventure, and a testament to the enduring appeal of a meticulously crafted diving watch. This article delves into the intricacies of the Deep Sea Dial Blu, exploring its design, functionality, market value, and its place within the broader Rolex landscape. We will also address frequently asked questions about this iconic model.

The Allure of the Deep Sea Dial Blu: A Visual Masterpiece

The defining feature of the "Dial Blu," officially known as the D-Blue dial, is its stunning gradient that transitions from a vibrant electric blue at the top to a deep, inky black at the bottom. This gradient is not merely an aesthetic choice; it's a deliberate homage to James Cameron's historic solo dive to the Mariana Trench in 2012 aboard the Deepsea Challenger submersible. Rolex partnered with Cameron on this groundbreaking expedition, and the D-Blue dial was introduced to commemorate this feat of human ingenuity and exploration.

The dial's visual depth mirrors the ocean depths it represents. The contrasting hues evoke the transition from sunlight-pierced surface waters to the crushing darkness of the abyss. The "DEEPSEA" inscription in bright green echoes the color of the Deepsea Challenger submersible, adding another layer of historical significance. The combination of the gradient blue-to-black dial and the vibrant green lettering creates a captivating visual effect that sets the Deep Sea Dial Blu apart from other Rolex models.

Beyond the color gradient, the dial features the classic Rolex layout with luminous hour markers and hands, ensuring optimal legibility in all lighting conditions, a crucial requirement for a professional diving watch. The Chromalight display emits a long-lasting blue luminescence, further enhancing visibility in low-light environments. The robust construction of the dial, coupled with the scratch-resistant sapphire crystal, ensures its durability and resilience against the harsh conditions encountered during deep-sea diving.

The Ref. 136668LB: A Specific Exploration

While "Rolex Deep Sea Dial Blu" can refer to several models featuring the D-Blue dial, the Ref. 136668LB is a specific iteration worth examining. While the provided information mentions searching for Ref. 136668LB on Chrono24, it's important to clarify that this reference number is not a typical Rolex reference. This could be a typo, a custom modification, or a reference specific to a particular dealer or market. Therefore, focusing on the more common and recognizable references associated with the D-Blue dial is more pertinent. These are primarily the 116660 and the later 126660 models.

Core Features and Functionality: Built for the Deep

Regardless of the specific reference, the Deep Sea Dial Blu models share a set of core features designed for extreme underwater performance:

* Ringlock System: This patented system is the cornerstone of the Deep Sea's exceptional pressure resistance. It comprises three key elements: a massive 5.5 mm-thick domed sapphire crystal, a nitrogen-alloyed steel compression ring, and a Grade 5 titanium case back. This innovative design allows the watch to withstand the immense pressure encountered at depths of up to 3,900 meters (12,800 feet).rolex deep sea dial blu

* Helium Escape Valve: As divers descend to great depths, they often breathe a helium-rich gas mixture to avoid nitrogen narcosis. Helium molecules are smaller than air and can penetrate the watch case. During decompression, the helium can expand rapidly, potentially damaging the watch. The helium escape valve automatically releases the trapped helium, preventing damage and ensuring the watch's integrity.

* Oyster Case: The robust Oyster case, crafted from Oystersteel (Rolex's proprietary 904L stainless steel), provides exceptional corrosion resistance and durability. The Triplock winding crown, featuring a triple waterproofness system, further reinforces the watch's water resistance.

* Movement: The Deep Sea is powered by Rolex's in-house Calibre 3235 (in newer models like the 126660), a self-winding mechanical movement renowned for its precision, reliability, and efficiency. It features a Chronergy escapement, offering greater energy efficiency and a longer power reserve of approximately 70 hours. The movement is also equipped with a Parachrom hairspring, providing greater resistance to shocks and magnetic fields.

* Oyster Bracelet: The Oyster bracelet, crafted from Oystersteel, provides a comfortable and secure fit. It features the Glidelock extension system, allowing divers to easily adjust the bracelet length to accommodate a wetsuit.

Market Value and Investment Potential: Navigating the Price Seas
