Case material: Steel; Charge: Automatic; Conditions: New Presentation condition : With dealer guarantee ; Price on request Gmtbroker Reference: Q8018420 True Second (aka Dead Beat Seconds): Rather than a smooth running seconds hand, the hand on this watch ticks second by second, allowing the wearer to measure time more precisely. The ticking seconds hand is powered by a separate dedicated hairspring positioned near the center of the movement. Separating the hairsprings enable the movement to maintain its amplitude despite the significant additional energy required to power the jump of the seconds hand. - Stainless steel case polished bezel ring & lugs, brushed finished case edge. - Very fine grained silver dial. - Polished applied index hour markers. - Luminous (cream colored) dot hour markers painted on the case ring surrounding the dial but under the crystal. - Polished baton shaped hands with cream colored luminous fill. - Date window located at the 3 o'clock position. Additional features: - Independent hour adjustment while the minute & seconds continue to run, allows for convenient adjusting the time while traveling. - Hour hand & date can be adjusted forward or backward without risk of damaging the movement. - Jaeger LeCoultre Caliber 770, equipped with JLC's Gyrolab® balance, beats at 28,800 vph, composed out of 275 parts, contains 36 Jewels & has an approximate power reserve of 40 hours. - As with all JLC watches this watch has undergone a rigorous 1000 (41 days) test before leaving the factory.
