The watch shown is the 126710BLNR. Homages follow other references too, so compare shape and scale.

How to recognise one

Eight marks make the look. The count says how many of the 24 homages keep each one.

  • Two-colour 24-hour bezel

    15 of 24 keep it. A bezel split into two colours, black and blue here, numbered every two hours up to 24.

  • Arrow GMT hand

    22 of 24 keep it. A fourth hand with an arrow tip points at the 24-hour bezel; on the 126710BLNR it is blue.

  • Date at 3

    20 of 24 keep it, 3 not compared yet. A date window at 3 sits under a magnifier on the crystal.

  • Triangle at 12

    9 of 24 keep it, 15 not compared yet. A lumed triangle at 12 that points to the centre of the dial.

  • Round hour plots

    7 of 24 keep it, 16 not compared yet. Lumed circles at most hours, with bars at 9 and 6.

  • Mercedes hour hand

    5 of 24 keep it, 19 not compared yet. The hour hand carries a ring with three spokes near its tip.

  • Crown guards

    2 of 24 keep it, 22 not compared yet. The case swells into two shoulders either side of the crown.

Each close-up covers about 12.5 mm of watch, using the listed case width and estimated photo edges.
