If you’re looking at this you’ll already know that these end-pieces are super-rare.
I discovered that the hard way myself so had these laser-cut copies made and finished them off by hand.
They work pretty well and have been tested out on one of my own Monacos with a genuine/original bracelet.
They come as a pair and with a genuine Mk1 bracelet they should just drop straight on.
You can also use them with the non-Heuer specific NSA bracelets (like Squinky sells) but you need to tweak the loops on the bracelet – easy job.
So, if you’re looking to preserve your originals or just need some end-pieces to complete a bracelet, these could be your answer.
I have a few sets, so give me shout if you’re interested in buying some.
