Pilot's Watch Double Chronograph Steel (IW377801)
The IWC Pilot's Watch Double Chronograph (ref. IW377801) features a mechanical automatic movement with approximate 44-hour power reserve; matte black dial; chronograph function with 30-minute register at 12 o'clock and 12-hour register at 6 o'clock; small seconds subdial at 9 o'clock; day & date displays at 3 o'clock; split-seconds hand for intermediate timing; sapphire-crystal, transparent case back; and 46mm (17.5mm thickness), stainless steel case on a black alligator strap with a stainless steel deployant clasp.
A particularly conspicuous feature on the double chronograph is the third push-button at “10 o’clock”. This can be used to stop the split-seconds hand at any time and to synchronize it again with the chronograph seconds hand, making it ideal for timing laps or intermediate times.
