  2. 2022
    Fifty and a new heart

    For the 50th anniversary the ref. 16202 replaced the 15202 as a faithful homage to the original 5402. In December 2022 a steel example sold at Phillips New York for 107,100 dollars against a 40,000 to 80,000 estimate.

    The Jumbo carries on

    The ref. 15202 kept the 39 mm Jumbo case and calibre 2121 from 2000, first adding a silver dial and later pink gold. For the 40th anniversary in 2012 it was reworked as a homage to the 5402, with Petite Tapisserie dial and AP logo at six.

    A chronograph at twenty-five

    The first Royal Oak chronograph, reference 25860, arrived for the line's 25th anniversary, powered by a 5.5 mm-thick calibre 2385.

Help

What is lug width?

The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.

Measure it in 30 seconds

  1. Take the strap off, or look at the back of it: many straps print their width.
  2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
  3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

Strap, quick release or system?

Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
