Mondaine leather strap plain. Authentic Mondaine Swiss Railway Watch Strap with Mondaine stamped on the inside of the leather strap, and embossed on the buckle.
You have a choice of three colours – black, red and white and a choice of sizes – 12mm, 16mm, 18mm, 20mm and 22mm (not all straps are available in all variations). (Please note that the 18mm mat finish version has been discontinued and is no longer available).
This refers to the width of the gap between the two stanchions which house the strap. If you are unsure, the size is stamped on the inside of the watch strap on the tail end; try angling a light, or sunlight, over it if it is not immediately apparent. For some sizes, an extra long strap is available; the total length of the XL strap is 92mm from the securing point to the buckle pin position, plus 103mm from the securing point to the last hole; total 195mm.
There is also a choice of polished chrome or matt chrome version of buckles. Usually the mat version matches the case on the black faced watch but of course, the choice is yours. The difference is slight.
