The initial foray into blue for the Submariner wasn't in steel, but rather in precious metals. Rolex first introduced blue dials and bezels on gold Submariner models. This strategic move positioned the blue Rolex Sub as a more luxurious and less overtly tool-like variant compared to its black steel counterpart. These early gold models were often seen as status symbols, blending the robustness of the Submariner with the prestige of gold and the captivating hue of blue.

The true breakthrough for the Rolex Blue Submariner came with the introduction of steel models featuring blue elements. This made the captivating blue aesthetic more accessible to a wider audience. The combination of robust Oystersteel with the vibrant blue dial and bezel proved to be incredibly popular, creating a watch that was both sporty and sophisticated. This marked a significant moment, solidifying the blue Submariner Rolex as a distinct and highly sought-after member of the Submariner family.

The introduction of Cerachrom (Rolex's proprietary ceramic) bezels further elevated the Rolex Blue Submariner. Cerachrom bezels are virtually scratch-proof, fade-resistant, and incredibly durable, enhancing both the functionality and the visual appeal of the watch. The deep, lustrous blue of the Cerachrom bezel, especially in models like the "Bluesy" and "Smurf," became instantly recognizable and contributed significantly to the modern Rolex blue Sub's iconic status.

The blue Sub Rolex is available in various materials, each influencing the shade and overall aesthetic of the blue. Oystersteel models offer a sporty and versatile look, while yellow gold and white gold models exude luxury and exclusivity. The blue hue itself can vary slightly depending on the material and model, ranging from a vibrant sunburst blue on some dials to a deeper, more matte blue on others. Rolex's mastery of materials ensures that the blue Rolex Sub remains visually stunning and exceptionally durable, regardless of the chosen material.

The dial and bezel are the defining blue elements of the Rolex Blue Submariner. Dials can feature a sunburst finish, creating a dynamic play of light, or a more matte finish for enhanced legibility in all conditions. The Cerachrom bezel, a hallmark of modern blue Rolex Submariner models, offers exceptional scratch resistance and color retention. The combination of dial and bezel colors creates a cohesive and striking aesthetic that sets the blue Submariner Rolex apart.

Several Rolex Blue Submariner models have achieved iconic status, earning nicknames and fervent collector interest:

• "Bluesy" (e.g., 116613LB, 126613LB): The "Bluesy" is perhaps the most recognizable Rolex Blue Sub. It features a stainless steel and yellow gold (Rolesor) construction with a vibrant blue dial and blue Cerachrom bezel. The combination of gold and blue creates a luxurious yet sporty aesthetic that is instantly recognizable and highly sought after.
• "Smurf" (116619LB): The "Smurf" is an all-white gold Rolex Blue Submariner with a blue dial and blue Cerachrom bezel. Its nickname derives from its predominantly blue appearance, reminiscent of the cartoon characters. The "Smurf" is a statement piece, showcasing the luxury and exclusivity of a full gold blue Rolex Sub.
• Oystersteel Blue Bezel Submariners (e.g., 126610LV "Bluesy" - though technically steel/gold, and 126619LB White Gold): More recent models in Oystersteel with blue Cerachrom bezels (sometimes paired with black dials in specific configurations) offer a more contemporary and sporty take on the blue Rolex Submariner aesthetic. These models maintain the robustness of Oystersteel while incorporating the captivating blue bezel, appealing to those who prefer a less overtly precious metal look.

Beneath the captivating blue exterior, the Rolex Blue Submariner houses Rolex's renowned movements, known for their precision, reliability, and longevity. Models typically feature self-winding mechanical movements like the Caliber 3135 or the newer Caliber 3235, depending on the specific reference and production era. These movements offer exceptional accuracy, chronometer certification, and robust performance. Functionally, the blue Sub Rolex retains all the dive watch capabilities of the standard Submariner, including water resistance to 300 meters (1000 feet), a unidirectional rotating bezel for timing dives, and highly legible displays even in low-light conditions.

The blue colorway adds a layer of sophistication and distinctiveness to the classic Submariner design. It's a color that evokes the ocean, adventure, and a touch of luxury. The blue Rolex Sub stands out from the more common black models, offering a way to express personal style while still enjoying the iconic status of the Submariner.

Certain Rolex Blue Submariner models, particularly vintage or limited production runs, can be quite rare. High demand, coupled with Rolex's controlled production, often leads to waiting lists at authorized dealers and strong prices in the pre-owned market. This scarcity and desirability contribute to the blue Submariner Rolex's potential as an investment.

Owning any Rolex carries significant prestige, and the Rolex Blue Submariner is no exception. Rolex's reputation for quality, innovation, and enduring design ensures that their watches retain value over time. The Submariner, in particular, is a cornerstone of horological history, and the blue Rolex Sub within that lineage benefits from this established legacy.

Historically, Rolex Blue Submariner models have performed well in the pre-owned watch market. While past performance is not indicative of future results, the combination of Rolex's brand strength, the Submariner's iconic status, and the desirability of the blue colorway suggests that well-maintained blue Rolex Sub watches are likely to hold their value and potentially appreciate over time. However, it's crucial to conduct thorough research and understand market trends before considering any watch as a purely financial investment.

The primary route for purchasing a new Rolex Blue Submariner is through authorized dealers. However, due to high demand, waitlists are common, especially for popular models like the "Bluesy" and certain Oystersteel blue bezel variants. The grey market offers immediate availability but typically at a premium above retail price. Weigh the pros and cons of each approach – patience and retail price from an AD versus immediate availability but higher cost from the grey market – based on your priorities.

Retail prices for Rolex Blue Submariner models are set by Rolex and can be found on their official website or through authorized dealers. However, actual market prices, especially in the grey market, can fluctuate based on demand, model rarity, and overall market conditions. Be prepared for potential premiums above MSRP, especially for highly sought-after references. Availability can also vary significantly, with some models being more readily available than others.

If considering a pre-owned Rolex Blue Submariner, thorough authentication is paramount. Purchase from reputable dealers with a proven track record and consider professional authentication services. Examine the watch carefully, checking for matching serial numbers, correct paperwork (if available), and signs of originality. Understanding the specific reference and its characteristics is crucial to avoid counterfeit or misrepresented watches.

Clean your blue Rolex Sub regularly with a soft cloth and lukewarm soapy water. Avoid harsh chemicals or abrasive cleaners. Rolex recommends a full service by an authorized service center every 5-10 years, depending on usage, to ensure optimal performance and longevity of the movement.

Store your Rolex Blue Submariner in a safe, dry place, preferably in its original box or a watch case. Avoid exposing it to extreme temperatures, strong magnetic fields, or direct sunlight for prolonged periods. Handle your watch with care to prevent scratches and impacts.
