The Rolex GMT-Master II, particularly the reference 116710BLNR affectionately known as the "Batman" due to its blue and black bezel, has captivated watch enthusiasts for years. Its striking "Schwarz Blau" (German for "black blue") color scheme, coupled with its robust construction and legendary reliability, solidifies its position as a highly sought-after timepiece. This article delves into the intricacies of the Rolex Schwarz Blau, exploring its history, technical specifications, variations, and its place within the broader Rolex GMT-Master II lineage.
The foundation of the Rolex Schwarz Blau's appeal lies in its Oyster architecture. This robust case, crafted from highly corrosion-resistant Oystersteel (Acero Oystersteel, as referenced in the provided text), is a hallmark of Rolex's commitment to enduring quality. Rolex's meticulous use of Oystersteel, a 904L stainless steel alloy, ensures exceptional resistance to scratches, corrosion, and the ravages of time. This material, superior to many 316L stainless steels, contributes significantly to the watch's longevity and its ability to maintain its elegant appearance even after years of wear. The seamless integration of the case, crown, and crystal creates a water-resistant seal, capable of withstanding significant pressure, a testament to Rolex's mastery of watchmaking engineering.
The "Schwarz Blau" moniker perfectly encapsulates the watch's distinctive bezel. This bi-directional rotating bezel, a defining characteristic of the GMT-Master II, features a Cerachrom insert in black and blue. Cerachrom, a proprietary ceramic material developed by Rolex, is virtually scratch-proof and resistant to fading, ensuring the vibrant colors remain true even under harsh conditions. The crisp, contrasting colors of the black and blue segments on the bezel not only enhance the watch's aesthetic appeal but also serve a crucial functional purpose. Each segment represents a different time zone, allowing the wearer to track two distinct times simultaneously. This functionality is particularly valuable for frequent travelers or individuals working across multiple time zones.
The heart of the Rolex Schwarz Blau beats the calibre 3186, a self-winding mechanical movement entirely manufactured by Rolex. This movement embodies the brand's dedication to precision and reliability. Its robust construction, incorporating a Parachrom hairspring, contributes to exceptional shock resistance and accuracy. The Parachrom hairspring, made from a paramagnetic alloy, is ten times more resistant to shocks than a traditional hairspring, ensuring the watch maintains its timekeeping precision even during strenuous activities. Furthermore, the calibre 3186 boasts a power reserve of approximately 48 hours, allowing for uninterrupted timekeeping even if the watch is removed for a period.
