I should have researched this before posting on here.
It is a known thing that prolonged wear of a silicone watch strap can cause irritation/burns and its not just after market straps but Apple/Garmin users have also reported suffering from this.
I've never fitted the original bracelet but it seems for extended wear such as camping at LM for 6 days if I really want to wear my baby Dreadnought I'll have to put it on the bracelet.
I am away from UK until July so its lucky I also brought my Anniversary Everest with me, which is on its Jubilee bracelet.
