An iconic IWC Chronograph Pilot watch with a very cool Mecha-Quartz movement. The movement was made by Jaeger LeCoultre. The JLC caliber 630 'Mechaquartz' caliber is a movement with a quartz base powering a mechanical chronograph. Since the chronograph is mechanical, it has the same feel as a conventional chronograph movement, including mechanical zero reset. But the Mechaquartz is much more compact than a conventional automatic chronograph movement. The 630 JLC caliber was used by Jaeger LeCoultre and IWC. Black Chronograph Dial with Date window between the 4 and 5 o'clock hour markers. The case measures 36mm without crown and chronograph buttons. The watch is used but only shows very light marks on the bezel and the case back. A good polish would probably make it look as good as new. The new aftermarket leather watch band has the IWC buckle. Has a battery and works nicely.
