With a tape measure
Pass the ribbon around the wrist, just above the bone, without tightening. Read the measurement at the crossing point: this is your wrist size.
Template
The template to print to measure your wrist size and choose the correct length.
You can measure your wrist circumference using a tape measure. If you do not have a tape measure, you can cut out and use the BRM Chronophages template opposite. Allow half a centimetre more than the bare measurement if you like to wear the watch loose.
Pass the ribbon around the wrist, just above the bone, without tightening. Read the measurement at the crossing point: this is your wrist size.
Print the template below at its actual size, cut it out, wrap it around your wrist and read the measurement where the band overlaps.
At actual size, without scaling.
Following the dotted line.
Around the wrist, without tightening.
Read the marking at the crossing point.
This strip is drawn in actual millimetres: printed at 100%, it comes out at the correct size. On screen, however, it depends on your display resolution — do not measure anything on it.
B.R.M — Wrist size template
Cut out the strip following the dotted line, wrap it around your wrist without tightening, and read the marking at the point where the strip overlaps. First check that the scale reference measures exactly 50 mm: if not, reprint at 100%, without 'fit to page'.
Before printing: in the print window, select 100% scale and untick 'fit to page'. Then check the scale marker against the ruler: if it does not measure 50 mm, the measurement will be incorrect. In the absence of a ruler, a bank card measures 85.6 mm in length.
Wrist size determines the length; the width depends on the model. Here is the size guide and their compatibility:

The introductory text and the four steps come from the B.R.M boutique — page 'Determine your strap size', CMS identifier 7 (view the original page), including the typographical error "BRM Chronophages", left as is. The strap width guide is reproduced word for word from the frequently asked questions. The printable ruler is new: the boutique only offered a PDF, still downloadable above. The half-centimetre of comfort is a recommendation from the prototype, to be validated by the workshop.
