Hello,

I have a 516 (first picture) and am looking for the second one. I received two offers, displayed in the other pictures. I'm worried because the shape is completely different. Also, the fonts of the numbers are different. Are they legit?

My watchmaker says #2 is good (top) but #3 looks no good at all (bottom).

Another pic. #2 top, #3 bottom. Pay attention to the distance between numbers and borders. It’s completely different.

The ones depicted in that book (only one pic, and rather small) look also different. The production is very varied.

I asked several people who are more expert than me. There is a general agreement that both end links are legit. I therefore decided to keep them.
