Remove the pin and collar.
Take a small pair of cutting pliers and squeeze (gently) the collar in the center to close it up a bit. Test by pushing in the pin to make certain the pin doesn't drop through before reassembly. Not the best solution, but usually works if you don't have spare collars about.
Kip, if you'll indulge me I should like to ask do you know why this happens from your experience? If the pin and collar have been cozy for some time, why should it suddenly work loose - unless there is wear? In which case a new pin/collar would be the definitive solution?
Thanks

Usually it is just wear and tear over time. Dirt can be another issue that also can cause premature wear. Sometimes dirt/body cheese that gets in can actually help hold a wearing pin/collar and when it gets clean(ed) the pins get loose. More frequently this happens on links that have been involved in the adjustment process of a bracelet, but not always.
Yes, a new pin collar would be the best solution, but these are not always readily available. A local watch repair place may have some.

It's not easy to source pins and collars, is it?

Thanks for that Kip, I do like to understand the root cause if possible.

It would be very handy if all bracelet manufacturers supplied extra pins (and collars if applicable) with any bracelet/watch purchased. Hardly any cost at all, surely, and such a benefit to the recipient. CW, and other manufacturers should also have spare links for sale, should a bracelet not be long enough, although that's probably a rare event. The problem in that case is generally lost links.
If (when?) it happens again, I’ll try swapping for another pin/collar set from an extra link. Hopefully that will take care of it....assuming it happens again.

Half links would be a plus as well.

There’s a compression detent in the centre of the collar which matches a corresponding ‘dent’ in the centre of the pin which together provide a very positive click when the pin has been pushed home as well as stopping it coming back out. It’s feasible that the detent in the collar may have been broached out when an adjustment tool has been used.
Kip’s suggestion to slightly compress the collar is good. I might be tempted to very gently tap a knife edge across the collar indent.
