The chronograph and second time-zone functions are united within a single model: the Master Compressor Chronograph Ceramic, an exclusive series limited to 500 pieces. The hi-tech ceramic case, protected by a sapphire crystal, is characterised by its high resistance to scratches and by the presence of a crown with a compression key, patented by the brand, which ensures maximum water-resistance. The semi-opaque black dial features luminescent hour and minute hands and a red chronograph seconds hand, while the GMT hand occupies a subordinate position while maintaining optimal legibility. The day/night indicator is also present, appearing in a small porthole below the Jaeger-LeCoultre inscription. The chronograph hour and minute counters are located at 3 and 9 o'clock, while the continuous seconds hand and date window are placed at 6 o'clock and between 4 and 5 o'clock respectively. For the movement, the House has relied on the automatic 757, with a 65-hour power reserve.
