i just won a 1069 bracelet and i think i saw
it here on a lyre lugged Speedy, so does somebody know the endlinks i need?
The bracelet looks like this.

 

I have a De Ville 146.017 and it came with the bracelet 1069 with 524 end links (19mm).

Hope that helps

 

524

19mm so may fit your straight lug speedy. I use mine on this (2 different examples)

 

My 1069 has 524 end links as well - and incidentally, it fits the aqua terra quite nicely as well
