White gold Rolexes are no small investment. To make the right choice for your watch box, it helps to know what sets these two Rolex Submariner watches apart. Let’s get into the differences between each of these blue-bezeled icons.
The Tale of Two Blue Submariners: Cookie Monster and Smurf

Rolex never confirmed the nicknames, but both “Smurf” and “Cookie Monster” were already entrenched as proper nouns in the watch world. The moniker was as intuitive for the former as it was for the latter, especially since both Rolex nicknames were drawn from popular culture. For the “Smurf,” the nickname came naturally. Its all-blue look and white lume reminds a lot of collectors of the eponymous cartoon character. The “Cookie Monster,” with its black/blue bezel and dial combo, loosely mirrors the quirky Sesame Street favorite.
Of course, what really makes them both special is the solid 18k white gold finish. A material usually reserved for the most exclusive Rolex watches. It’s also worth noting that unlike stainless steel watches, white gold Rolex watches are often called “stealth wealth” due to their more understated nature. Yellow gold watches shout luxury and prestige, while a white gold Rolex says very little to the average passerby. A common joke is that these watches could be the “plainest Submariner” to the untrained eye but feel like solid gold on the wrist of collectors.
The biggest difference between the two really comes down to color, although both share the same colorful blue Cerachom bezel. Cerachrom refers to Rolex’s proprietary scratch-resistant ceramic bezel. The Swiss watch maker introduced the innovation in the mid-2000s as a replacement for the company’s aluminum inserts. You can learn more by visiting our Rolex Submariner bezels guide. The blue bezel is the visual signature that both watches are known for by collectors and the foundation of both models’ nicknames.
Rolex Smurf

Rolex first introduced the Smurf in 2008. This was the first white gold Submariner to feature this kind of striking all blue appearance. It was a daring design move for Rolex at the time and made a very powerful statement, as it was instantly recognizable as a blue-on-blue combination. Even since its release, the Smurf has had quite the cult following.

Rolex Cookie Monster

The Cookie Monster was introduced in 2020 as a modern reinterpretation of the Smurf. The new model has a number of technical and design improvements. The black dial provides a dramatic contrast with the blue bezel as opposed to the matched look of the Smurf. Rolex has also improved the case architecture with a 41mm diameter and refined lugs for a more comfortable wear. The new Caliber 3235 movement is more precise and provides a longer power reserve.

Head-to-Head Comparison: Cookie Monster vs. Smurf
While both watches share the same white gold construction and striking blue bezel, the “Cookie Monster” brings a modern edge with its larger 41mm case, black dial, and upgraded Caliber 3235 movement. The discontinued “Smurf,” with its all-blue charm, remains a favorite among collectors for its rarity and classic Submariner proportions.

The Collector’s Choice: Which is the Better Investment?

Both watches make solid investment pieces. They just appeal to different kinds of collectors. Smurf is discontinued which means values will only go up in time as demand increases and supply will be finite. The unique all blue color and 12 year run of production have also enshrined the lore of this timepiece. This watch is for a collector who is in it for both the wearing and the investment value.
Production of the Cookie Monster is ongoing, and as a result is easier to find new from an authorized dealer than the Smurf. Even so, considerable backorders are still the norm for Rolex models in high demand and in precious metals. The technical merits of the Cookie Monster as a modern watch with the advanced Caliber 3235 movement are also more to the modern tastes and it can be seen as the more desirable watch if one had to choose. On the secondary market, both are priced higher than the original retail price. This is not unexpected for any white gold Submariner due to high demand, but Smurf values have remained high due to their discontinued status and Cookie Monster values are high due to demand for this most sought-after current-production model.
The Final Verdict on These Iconic Rolex Watches

What it really comes down to is the kind of collector you are and the types of watches you like to wear. The Smurf has a bolder monochromatic design featuring the bright blue dial and bezel. A true statement piece and discontinued as well. The Cookie Monster has a more classic and versatile appearance featuring the black dial. It makes a slightly more understated but equally luxurious daily wearer with the benefit of more modern Rolex technology.
