The most iconic Sinn imo. I've had this one for a while now and, at the time, I hesitated quite a lot if I should get the indices or numerals. Considering I already had a few divers with either stick or round indices, I'm glad I went with the numerals.
I also think it's more appropriate for a Pilot watch.
I have the bracelet, but it's such a strap monster so I almost never use it.
