Louis Erard Regulator Power Reserve,It is powered by ETA Peseux 7001 RE9 mechanical hand-winding caliber with Louis Erard complication. This movement is based on well-known ETA 7001 movement and one extra module developed by Louis Erard in cooperation with the manufacturer of Swiss-made movements, Soprod S.A. A sober white dial showing hours by Roman numerals on an offset subdial at 12 o’clock, small seconds at 6 o’clock, and power reserve at 9 o’clock accentuate the classic sophistication of a richly nuanced collection.
Regulator-type watches are typically typified by their use of three distinct dials for the hours, minutes, and seconds. Minutes are displayed on the bigger important dial whereas an higher sub dial is used to point the hours and a decrease one is used to point the seconds. 
The polished stainless steel case is water resistant to 165 feet (50 Meters or 5 ATM) and protected with an anti-reflective sapphire crystal on both sides. Additional comfort on the wrist ensures 100% leather black crocodile imitation strap with stainless steel folding clasp.
Although there are three sub-dials and four hands, the dial leaves an impression of tidiness and refined elegance.
White background makes the perfect combination with blue hands and beautifully written Roman numerals.
