Calling all Rolex enthusiasts! The legendary “Starbucks” GMT-Master, named for its vibrant green and black bezel resembling the coffee giant’s logo, continues to spark conversation within the watch-collecting world. While there’s technically only one reference number associated with this model (16750), variations exist, leading to the terms “Mk1” and “Mk2.” This comprehensive guide delves into the fascinating world of the Rolex Starbucks Mk1 and Mk2, empowering you to navigate their distinctions and choose the ideal timepiece for your collection.
A Legacy of Speed: Unveiling the History
The Rolex GMT-Master story begins in the 1950s, fueled by a need for innovation in aviation. Pan Am Airlines approached Rolex with a specific request: a wristwatch that could display the time in multiple time zones simultaneously. In 1954, Rolex answered the call with the GMT-Master. This revolutionary timepiece featured a 24-hour rotating bezel and a separate GMT hand, allowing pilots to track the time in their home zone while navigating across different time zones.
The “Starbucks” bezel, with its green and black color scheme, debuted in the late 1970s on the reference 16750. While the exact origin of the nickname remains unclear, some believe it stemmed from the bezel’s resemblance to the coffee chain’s logo, while others attribute it to the model’s popularity among airline personnel who frequented Starbucks. Regardless of its origin, the “Starbucks” moniker has become synonymous with this coveted Rolex GMT-Master variation.
Under the Hood: A Technical Breakdown
Despite sharing the “Starbucks” nickname and reference number (16750), the Rolex Starbucks Mk1 and Mk2 exhibit some subtle technical differences:
Movement:
Both models boast reliable automatic movements, but with a key variation:
- Rolex Starbucks Mk1: Powered by the highly regarded Rolex Caliber 1570. This robust automatic movement boasts:
- Automatic: The self-winding mechanism harnesses your wrist movement to power the watch, eliminating the need for daily manual winding.
- Caliber 1570: A reliable and proven automatic movement introduced in the 1960s. It features 26 jewels for smooth operation and a hacking function for precise time settings.
- Chronometer-certified: Each Caliber 1570 undergoes rigorous testing by COSC (Contrôle Officiel Suisse des Chronomètres) to guarantee exceptional accuracy. This certification ensures the watch maintains a daily rate of +/- 2 seconds, a testament to Rolex’s commitment to precision.
- Power reserve: Approximately 48 hours after the watch is fully wound.
- Rolex Starbucks Mk2: Powered by the modern and robust Rolex Caliber 3186. This advanced movement offers superior performance and reliability compared to the Caliber 1570. It features:
- Caliber 3186: Introduced in the 1980s, this movement offers superior performance and reliability compared to the Caliber 1570. It features 31 jewels for enhanced smoothness and a hacking function for precise time settings.
- Chronometer-certified: Similar to the Caliber 1570, the 3186 undergoes COSC certification, guaranteeing exceptional accuracy.
- Power reserve: Approximately 70 hours after the watch is fully wound. This extended power reserve is a significant improvement over the Mk1.
Here’s a table summarizing the key movement specifications:
| Feature | Rolex Starbucks Mk1 | Rolex Starbucks Mk2 |
|---|---|---|
| Movement | Rolex Caliber 1570 (Automatic, Chronometer-certified) | Rolex Caliber 3186 (Automatic, Chronometer-certified) |
| Power Reserve | Approximately 48 hours | Approximately 70 hours |
Materials and Construction:
Both the Mk1 and Mk2 prioritize robust construction with high-quality materials, but with a slight evolution:
- Case:
- Rolex Starbucks Mk1: Typically crafted from 316L stainless steel. This is a highly durable and corrosion-resistant material.
- Rolex Starbucks Mk2: Utilizes 904L stainless steel. This advanced steel offers superior corrosion resistance compared to the 316L used in the Mk1.
- Crystal:
- Rolex Starbucks Mk1: Often features an acrylic crystal. While offering good scratch resistance, acrylic crystals are more susceptible to shattering compared to sapphire crystals.
- Rolex Starbucks Mk2: Equipped with a sapphire crystal. This provides exceptional scratch resistance and maintains its clarity for extended periods. Sapphire crystals are the preferred choice for modern Rolex watches due to their superior durability.
| Feature | Rolex Starbucks Mk1 | Rolex Starbucks Mk2 |
|---|---|---|
| Case Material | 316L Stainless Steel | 904L Stainless Steel |
| Crystal | Acrylic Crystal | Sapphire Crystal |
| Water Resistance | 100 meters (10 ATM) | 100 meters (10 ATM) |
| Case Size | 40mm | 40mm |
| Bracelet | Jubilee (Stainless steel, Rolesor, or President) | Jubilee (Stainless steel, Rolesor, or President) |
Both models typically come equipped with a Jubilee bracelet. This five-link bracelet is known for its comfort and elegant drape. The Jubilee bracelet can be crafted from stainless steel, a two-tone combination of stainless steel and gold (Rolesor), or even full gold (President).
Functions and Features:
Despite the movement and material variations, both the Rolex Starbucks Mk1 and Mk2 offer the core functionalities that define the GMT-Master:
- Timekeeping: Displays hours, minutes, and seconds with clear and easy-to-read hands and indices.
- Date window: Displays the date at the 3 o’clock position.
- 24-hour rotating bezel: The iconic green and black bezel can be independently rotated to track a second-time zone.
- GMT hand: An additional hand that can be independently set to another time zone. The GMT hand can be adjusted without affecting the timekeeping function of the watch.
While the core functionalities remain the same, there might be slight variations depending on the specific model year and production run. For example, some later models might feature a slightly different luminous material compared to earlier Mk1 or Mk2 models.
A Matter of Style: Design and Aesthetics
Here’s where the true visual differences between the Rolex Starbucks Mk1 and Mk2 come into play:
Dial Design:
Both models share the classic Rolex GMT-Master dial layout with:
- Black glossy dial: A timeless and versatile background for clear readability.
- Applied hour markers: Typically made from white gold or luminescent material.
- Mercedes hands: A signature Rolex feature with a distinctive pointed hour hand resembling a three-pointed star.
- GMT hand: Typically differentiated by a colored arrow tip (red or green) to distinguish it from the hour and minute hands.
The key difference lies in the color of the lume plots and the presence of a magnifying Cyclops lens over the date window:
- Rolex Starbucks Mk1: Often features tritium lume plots. These plots have aged over time, developing a creamy yellow or light brown patina. This vintage aesthetic is highly sought-after by collectors who appreciate the history and character imparted by the aging of the lume material. The Mk1 might not have a Cyclops lens over the date window, depending on the specific production year.
- Rolex Starbucks Mk2: Utilizes Super-LumiNova lume plots. This offers a brighter and longer-lasting glow compared to tritium. The Mk2 typically features a Cyclops lens over the date window for magnified viewing.
Bezel Insert:
Both models boast the iconic green and black “Starbucks” bezel, but there might be slight variations in color and material:
- Rolex Starbucks Mk1: The green color on the bezel insert might appear slightly lighter compared to the Mk2. This is due to the natural fading of the bezel material overtime on some Mk1 models. The Mk1 bezel insert might be crafted from aluminum or acrylic.
- Rolex Starbucks Mk2: The green color on the bezel insert might appear slightly more vivid due to the use of potentially newer materials or less exposure to sunlight. The Mk2 bezel insert is typically crafted from ceramic.
Here’s a table summarizing the key design elements:
| Feature | Rolex Starbucks Mk1 | Rolex Starbucks Mk2 |
|---|---|---|
| Dial Lume | Tritium (aged patina) | Super-LumiNova (brighter, longer lasting) |
| Cyclops Lens | Optional (depending on production year) | Typically present |
| Bezel Insert Material | Aluminum or Acrylic | Ceramic |
| Bezel Insert Green Color | Potentially lighter green | Potentially more vivid green |
Case and Bracelet:
As mentioned earlier, both the Rolex Starbucks Mk1 and Mk2 utilize the iconic Jubilee bracelet. This five-link bracelet is known for its comfort and elegant drape, offering a timeless complement to the watch’s overall aesthetic. However, some collectors might have a preference for different bracelet options available for the reference 16750:
- Stainless Steel Jubilee: The most common option, offering a sporty and versatile look.
- Rolesor Jubilee: A two-tone bracelet combining stainless steel and 18k gold for a touch of luxury.
- President Bracelet: A full 18k gold bracelet, that exudes ultimate opulence.
The choice of bracelet material ultimately depends on your personal style and budget.
Water Resistance: Both the Rolex Starbucks Mk1 and Mk2 boast a water resistance rating of 100 meters (10 ATM). This makes them suitable for swimming and recreational water activities. However, it’s essential to avoid exposing the watch to hot water or sudden changes in temperature, as this can damage the gaskets that ensure water resistance.
Brand Image:
The Rolex name carries immense brand prestige, and the Starbucks GMT-Master is no exception. Both Mk1 and Mk2 models hold a unique position within the Rolex collector’s universe:
- Rolex Starbucks Mk1: Embodies a vintage aesthetic with its tritium lume and potentially lighter green bezel. This historical significance and “aged” character resonate with collectors who appreciate a watch with a story.
- Rolex Starbucks Mk2: This represents a more modern interpretation with its Super-LumiNova lume, potentially more vivid green bezel, and likely inclusion of the Cyclops lens. This appeals to collectors who prioritize functionality and a slightly more contemporary aesthetic.
The Final Lap: Choosing Your Champion
With a comprehensive understanding of the technical aspects, historical context, and design nuances of both the Rolex Starbucks Mk1 and Mk2, you’re well-equipped to make an informed decision. Here’s a quick guide to help you select your ideal Starbucks GMT-Master:
Choose the Rolex Starbucks Mk1 if:

Remember: Both the Mk1 and Mk2 are exceptional timepieces, each holding a unique charm within the Rolex Starbucks GMT-Master legacy. Ultimately, the decision boils down to your personal preferences for specific features, aesthetics, and historical significance.
Here are some additional factors to consider when choosing your Rolex Starbucks GMT-Master:
- Condition and Price: The specific condition of the watch, including the case, dial, bezel insert, bracelet, and service history, plays a crucial role in determining its price. A well-preserved Mk1 with box and papers might command a higher price than a Mk2 in lesser condition without original documentation. Carefully research market prices for both models to ensure you get a fair deal.
- Investment Potential: While both models are highly sought-after, the Mk1, due to its vintage nature and potentially limited production run within the reference 16750, might hold a slight edge in terms of potential investment appreciation. However, market fluctuations and overall watch condition significantly impact value.
- Trusted Sellers: Always purchase your Rolex Starbucks GMT-Master, whether Mk1 or Mk2, from reputable dealers or auction houses. This ensures authenticity and a smoother buying experience.
