Afternoon All

Having some work done on my old SeaDweller. The bezel has always been a tad temperamental so I asked James (Hyman - recommended on here!) to have a look, which he has done - so far without success!

The question is whether the recess on the inside wall of the bezel which may require a runner gasket? Understandably, James doesn't want to fit a similar gasket in case it caused an issue and I couldn’t get the bezel back off if it proved to not be correct.

Does anyone know if there should be a runner gasket and if so what size etc?

Thanks! Francis
