Well I finally ordered my first Sinn today. I've been looking and reading for quite a while. Couldn't decide if I wanted acrylic or saphire. I was worried about the look of of the saphire and how it would affect the black dial color. I certainly like the idea of no scratches but I noticed that a couple of people mentioned scratches and swirls to the exterior AR coating. That seemed to negate the whole reason for the saphire crystal. I ordered mine with the acrylic because it can be polished and I know the black face will look better without the bluish hue that is reflected with the coated saphire.
It should be here by Wednesday of next week. It's the Sinn 356 Flieger Acrylic on a strap. Just checked and it was infact the last one before the price increase. My order is marked complete and the item now shows out of stock. So glad I finally placed the order. I had started to order it Thursday night but was still unsure on the acrylic/saphire thing. They emailed me and said they were down to the last one so I ordered. I'm glad I did.
