I just wanted to check in and let you guys know how impressed I am with my new Sinn 556. It has gained a total of 3 sec in the last 11 days. I have only taken the watch off to shower everyday. I never realized the quality of Sinn watches. Are all of their automatics this accurate? I am hooked on these watches and I am going to shift my collection towards Sinn watches and stray away from Omegas for the most part.
