Hello, I have been in the market for a Sinn 556 a, however, the Dekla Turbulenz has caught My attention. It is similar in aesthetic and has a hardened case. However the Sinn has an impeccable reputation, quality and high resale value. Does anyone have experience or care to comment on the Dekla. There are a lot of reviews and testimonials on the 556 but not so much on the Dekla.
