THE LIGHTNESS OF TITANIUM MEETS THE HARDNESS OF DIAMOND
RM 11-05 AUTOMATIC CHRONOGRAPH GMT
By using the pusher between 4 and 5 o’clock, the running chronograph can be reset without first having to stop the mechanism. This was originally developed for pilots in order to not waste time (and therefore accuracy) from stopping, resetting and starting the chronograph whilst crossing a navigational point.
While the chronograph function is activated, the hours and minutes show up the elapsed time thanks to the counter at 6 and 9 o’clock, the seconds are indicated by the central hands.
The RM 11-05 features a GMT hand filled with Super-LumiNova. It can be easily adjusted using the pusher at 9 o’clock.

Cermet’s physical properties are widely recognised, hence its frequent use in ballistic protections and in aerospace for re-entry shuttle components, exterior fuselage pieces and in the brakes on competition vehicles. Cermet has a mass to volume ratio of 4.1 g/cm3 and a hardness of 2,360 Vickers, comparable to other performance high-ceramic making it eminently suitable for use in bezels, an area highly vulnerable to scratches, while ensuring that entire assembly is light in weight.
This bezel and the caseback in grade 5 titanium are affixed to a caseband made of Carbon TPT®, which also contributes to lowering total weight.
The complete case construction is water-resistant to 50 metres thanks to two Nitrile O-ring seals and is assembled using 20 spline screws in grade 5 titanium and 316L stainless steel washers.
