A rubber-coated white gold protective ring placed on the case middle and secured on the side by seven self-locking screws, is enhanced by seven decorative elements straddling the bezel.These "ramparts" protect a monumental sapphire crystal a full 3.3 mm thick, glareproofed on both sides, which literally seems to rise out of the case.The Swiss replica Rolex 118239-WR Men's watch machined metal face of the C1 Tourbillon Gravity adopts Concord's hallmark layered constructionposed of twelve parts including four sapphire crystals, it is enriched by a dark DLC-coated grid which, like a lattice-work motif, accentuates the depth and perspective of the dial.The various subdials and time measurement indications are superimposed to create a sense of perfectly mastered space.In the foreground, the hour circle is off-centered between 10 and 11 o'clock and placed on a sapphire crystal providing glimpses of the mechanism gear-trains.
Surrounded by applied luminescent hour-markers, it features luminescent hands with a taut profile that requires particularly careful adjustment.Partially hollowed, they alternate solids and voids according to an asymmetrical pattern that results in strong pressure on the central stem.The power-reserve indicator between 7 and 8 o'clock Swiss replica Rolex 116233-BKSBRJ Men's watch displays the level of wind of the movement in respect to the available three and a half days of autonomy.It is accompanied by a spherical differential gear visible through the dial between 9 and 10 o'clock, which serves to transmit the barrel rotation to the power-reserve hand without influencing the movement operation.
During winding, this mechanism serves to compensate for the difference in speed between the counting train and the gear train of the power reserve.Just opposite the power-reserve indication, the trust index display provides information on the amplitude of the balance.It serves to preserve an extremely high level of precision by avoiding excessive tension in the mainspring due to maximum winding.By ensuring that the trust index hand remains at the centre of the graduated scale (and does not reach the + zone) when Swiss replica Rolex 116203-CSO Men's watch winding the watch, the user can maintain perfect accuracy.Clad in the Concord shade of blue and thus providing the only colorful accents on the dial, the power-reserve and trust index hands cleverly point to these two horological complications.
