Rolex has long been a benchmark of innovation, precision, and luxury in the watchmaking world. Two collections in particular – the green Submariner and the Day-Date – exemplify the brand’s evolution and enduring appeal. Each collection reflects a combination of design innovation, technical refinement, and cultural significance, making them both highly sought-after by collectors. 
Origins and Milestones
In 2003, Rolex introduced the first green Submariner, the ref. 16610LV, nicknamed the “Kermit,” to mark the collection’s 50th anniversary. This stainless steel diver featured a black dial and a green aluminum bezel – a first for a steel Submariner. The Kermit remained in production until 2010, when the next generation of replica Submariners, including the ref. 116610LV (“Hulk”), entered the market.
The current green Submariner, the ref. 126610LV, known widely as the “Starbucks” or sometimes the “Cermit” (a blend of Kermit and ceramic), was launched in 2020. Though sharing the iconic black dial and green bezel aesthetic, it embodies modern advancements in movement, materials, and ergonomics.
Bezel Material: Aluminum vs. Ceramic
The Kermit’s green aluminum bezel was groundbreaking at launch, offering a subtle, evolving patina over time. Each aluminum insert varies slightly depending on production year, giving collectors a unique, character-rich watch.
The Starbucks, in contrast, features Rolex’s Cerachrom ceramic bezel, which is virtually scratch-resistant and fade-proof. Its deep, olive-green hue is consistent and vibrant, maintaining color integrity under sunlight and saltwater exposure. 
Case Size and Design
The Kermit retained the classic 40mm case, while the Starbucks upgraded to a 41mm case with refined lugs, resulting in a more balanced and elegant wrist presence. The change reflects Rolex’s effort to modernize while preserving the Submariner’s distinctive silhouette.
Bracelet and Clasp
The Starbucks incorporates an updated Oyster bracelet with Glidelock, enabling fine adjustments without tools. The Kermit used an older folding clasp without such versatility, highlighting the practical improvements of the newer generation.
The Hulk’s Role
Between these models sits the Hulk (ref. 116610LV), produced from 2010 to 2020. Known for its green sunburst dial and monochromatic Cerachrom bezel, it serves as a transitional model bridging the Kermit and Starbucks in both style and movement.
Collectibility
The Kermit remains highly coveted, particularly rare variants like the “Flat 4.” Its limited anniversary production and unique aluminum bezel aging patterns contribute to strong appreciation in value. Meanwhile, the Starbucks enjoys strong secondary market demand due to its contemporary 41mm case, advanced Caliber 3235 movement, and limited dealer availability.
History and Significance
Introduced in 1956, the Rolex Day-Date quickly earned the moniker “President’s Watch” due to its association with world leaders, most famously U.S. President Lyndon B. Johnson. It was the first wristwatch to display both the day of the week and the date, coupled with a waterproof Oyster case and automatic movement.
The collection has consistently been produced in precious metals – gold and platinum – and remains a symbol of success and prestige. 
Design Evolution
Case Size: Originally 36mm, expanded to 41mm with the fake Day-Date II in 2008, then refined to 40mm in the Day-Date 40 series.
Bracelets: The iconic President bracelet features semi-circular three-piece links with a concealed Crownclasp. Some modern models offer leather straps or flat-link Oyster bracelets.
Dials and Bezels: Day-Date watches include a wide variety of dials – traditional stick markers, Roman numerals, diamond indexes, and even exotic materials such as meteorite or semi-precious stones. Bezels may be fluted, smooth, textured, or diamond-set.
Movement Evolution
Early references (6510, 6511) housed the cal. 1055, progressing through the cal. 1555, 1556, and 3055 with key innovations such as hacking seconds and the Single Quickset.
Later movements, like the cal. 3155, introduced the Double Quickset, simplifying calendar adjustments.
The current cal. 3255, featured in Day-Date 36 and 40, delivers 70-hour power reserve, anti-magnetic and anti-shock properties, and 14 patents, exemplifying Rolex’s continuous technical refinement.
Investment and Collectibility
Day-Date watches retain value exceptionally well due to their exclusive use of precious metals, historical significance, and technical innovation. Vintage models like the 1803, 18038, and 18078 offer entry points for collectors, while modern references in gold or platinum represent long-term investment potential.
Purchasing pre-owned models provides advantages: immediate availability, potential savings, and reduced initial depreciation. The timeless design, precision engineering, and scarcity of certain references make the Day-Date a coveted piece among enthusiasts and investors alike.
Both the green Submariner and Day-Date collections showcase Rolex’s mastery of design, technical innovation, and cultural resonance. The green Submariner illustrates the evolution of a professional sports watch across generations, while the Day-Date embodies status, prestige, and horological refinement.
Whether appreciating subtle variations in a vintage Kermit, the contemporary appeal of a Starbucks, or the enduring elegance of a Day-Date, collectors and enthusiasts alike recognize the significance of these watches in Rolex’s storied legacy.
