Hi, does anyone with a Wademan know of a similar but longer resin strap that will fit?

I want to wear this over clothing, and the standard strap is quite short. But as the strap fits onto a sort of "strap adapter" thing thats connected to the bezel, it's made quite short anyway, so a standard length strap fitted to the same adapter should make it quite long. It's the usual 16mm with shoulders about 22mm.

Cheers,
Dave
