Royal Oak Selfwinding Chronograph
A flyback chronograph in steel with a black “Grande Tapisserie” dial.
The 26240 is the 41 mm Royal Oak chronograph. Its movement, calibre 4401, has a flyback function: one press of the lower pusher resets the chronograph and starts it again.
Two counters, for 30 minutes and 12 hours, sit at 3 and 9 o’clock, with small seconds at 6. The date is between 4 and 5 o’clock.
This version is all steel with a black dial and black counters.
