<small>[[Reference:day-date|Day-Date]] → '''6611'''</small>
<small>[[Reference:day-date|Day-Date]] -> '''6611'''</small>


The 6611 is the reference that turned the Day-Date into the President. It arrived in 1957, about a year after the [[Reference:6510|6510]] and [[Reference:6511|6511]] originals, and it brought three firsts at once: the President bracelet, the "Superlative Chronometer Officially Certified" dial line, and a rebuilt caliber with a free-sprung Microstella balance and chronometer certification. The 6510 and 6511 invented the complication; the 6611 fixed its weak points and gave the line the bracelet and the dial text that define it today.
