The Calibre 3235 marked a strong evolution of the classic time-and-date movement at Rolex

Together with the different materials for the bezel, the other highly important difference between these two generations of green Submariners lies in what’s hidden inside, the movement. The Kermit 16610LV is powered by one of the most revered movements ever created by Rolex, the long-lasting calibre 3135, itself an evolution of the 3035 (1977-1988). The 3135 has been at the heart of all Submariner Date models from 1988 up until 2020. The Submariner Starbucks 126610LV is powered by a new generation of calibre, the 3235 (first seen in 2016 in the Datejust 41), which introduced major updates to the entire architecture, to the kinetic chain and the escapement, introducing the optimized Chronergy escapement.

The Calibre 3135 is known as one of the most reliable and enduring movements of its time. Measuring 28.5mm, like most Rolex replica watches uk base calibres, it beats at 4Hz, has a bi-directional automatic mechanism, 48 hours of power reserve and is regulated by a classic Swiss lever escapement with a Glucydur balance with Microstella adjusting nuts. It has existed with either a Nivarox or a blue Parachrom hairspring (which was gradually implemented as of 2008-2009). It is chronometer-certified by the COSC.

The Calibre 3235 marked a strong evolution of the classic time-and-date movement at Rolex, with the introduction of a highly revised architecture. The most important element is the Chronergy escapement, with an optimized geometry, offering better chronometric results and improved energy consumption. Together with an updated mainspring, the 3235 offers a generous 70h power reserve. It is equipped with a blue Parachrom hairspring, a Paramagnetic balance with Microstella nuts and a Paraflex antishock system. It retains the 28.5mm diameter dear to the brand, a 4Hz frequency, a bi-directional rotor (now with ball bearings) and the same jewel count (31 in both cases). It is, however, chronometer-certified by the COSC and then internally regulated to run within a -2/+2 seconds/day frame.

In the same vein as the evolution of the material used for the bezel, the bracelets used by rolex replica have evolved over the years. But here, seeing the Kermit and the Starbucks one next to another, you can feel how massive the differences are, specifically when looking at the clasps. Of course, both models are equipped with an Oyster bracelet made of 904L steel. The Kermit relies on the reference 93250, while the Starbucks uses the reference 97JB00. Both are brushed on flat surfaces and polished on the sides, and their length can be adjusted thanks to screws.
