Help with bracelet on vintage Omega Seamaster

I bought this watch for my recent wedding and am absolutely in love with it. I really don't want to wear anything else.

However, the bracelet came apart a few months ago and the watch hit the ground with a bump.

It's since been serviced and working well - but I still need to find a replacement strap.

Does anyone have any ideas or help on where I might find something? I spoke to a really helpful man in my local Omega shop and he suggested sending it to Switzerland, but that this would take several months.

Thanks in advance for any help!

Thanks. A few of them are very frayed and you can see some kind of mould on them. It did come off before and I'm worried it would happen. It's more than just that specific pin.
