Soft cloth strap in an OD#7 or possible Olive Green shade. Very comfortable to wear with plenty of adjustment for the larger wrist, my example came with 11 eyelets. Well stitched single piece construction with two loops for the spring bars. Two cloth keepers and a brushed buckle complete the look. The watch head sits tight between the loops, with the back resting on the strap i.e. the watch is not in contact with your wrist. I'm using it with my M.R.M.W A-17. Would work equally well with the A-11. An excellent price and I've seen images of this strap type in use with these watches from the period.
