1116 bracelet with screwed links

Good evening from Vienna, Austria!

I just put a 1116 bracelet for sale and wanted to ask the forum about 1116 bracelets with screwed interchangable links, since I do not want to sell a questionable bracelet.

A member droped me a line that he has never seen a 1116 with screwed links, all of his have double spring bar links.

So if you have a 1116 with screwed links, please post pics. I have 2 1116 with screwed links and one with double spring bar links. I think, that the screwed links execution is the oldest version of the 1116, but I might be wrong.

The one I put for sale here came with a Speedy 145.012.

I am happy to get more infos, thank you in advance and kind regards,

Max

I have a 1116 with a 31 stamped and no screw link. Yours is a 11 right? I read it's the older version.
As for the 1171, I guess the first series may have had screw links.
