The Glidlock was introduced to the Submariner Date family with the creation of the 116610 in 2010 and the Submariner No-Date with the 114060, in 2012. In precious metal versions of this bracelet there is a ceramic insert for the teeth of the micro adjustment system so as the protect them from wearing out prematurely.

Increasing water resistance and innovations to the case, dial and bracelet represent only part of Rolex’s focus on technical advancement and progress over the 67 year evolution of the Rolex Submariner.
Over the history of the model reliability, shock resistance and accuracy in time keeping has always been of paramount importance and this comes down to the movement driving the Submariner Date and No Date watches. The movements that have powered the Submariner including the 1575, 3035, 3135, with Date, and the 3000, 3130, without Date, are some of the most beloved in watchmaking history.
By 2010, for the Submariner Date 116610 and by 2012 for the Submariner No Date 114060, Rolex had switched over to truly excellent movements, respectively the 3135 and 3130 calibres, featuring the Parachrom hairspring. Like all 31-series movements, they beat at 4Hz, or 28,800vph, (this vibrational speed was introduced with the 3035, in 1981, in the reference 16800).
They featured a free sprung balance with Microstella adjustments screws, which has been a Rolex calling card since the 30-series movements. They both featured full transverse balance bridges as opposed to balance cocks in the previous 30-series movements, and overcoil hairsprings for more concentric breathing, as opposed to flat spirals. Further, these hairsprings were laser welded to the stud, while hairsprings in the 30-series of movements were glued. Being made from Parachrom these hairsprings were not susceptible the erosive effects of magnetism.
So how do you improve on an already impressive movement? In 2015, Rolex responded with the launch of the Calibre 3235, an automatic movement with date, which represented an incredible leap forward in terms of performance in terms of accuracy, reliability, shock resistance and power reserve. This movement would feature 90 percent new components, an increase of power reserve from 50 to 70 hours, a proprietary escapement that was 15 percent more efficient and 14 patents.
