WTB - GMT Master II Bezel Nylon Retaining Gasket
 

A friend of mine has the above watch but the nylon gasket that holds the bezel assembly on the watch case has snapped due to sand getting under the bezel.

Does anyone know where I can get one? Her watch is out of warranty, so looking to help her out if I can.

If someone knows the size of the nylon gasket, that would help too, the broken one is too stretched to measure accurately.

Thanks in advance.

Still looking for this.
