What are you actually worried about @Kryton57 – Getting it stolen? damaged? lost?
From my personal opinion (and youve kinda said yourself) – the watch is for wearing – and ive worn my nice watches while working/living/holidaying in other countries before (some good, some not so good) and never experienced any issues with damage or theft.
I wear mine on Nato straps, and maybe takes attention away from them.
However the key is to be sensible out and about. You’ll be in a group, and unlikely to be raucous too with the self professed group age.
Only drugs youll be looking for is Voltarol by the sounds of it…..
