Sinn 6012vsSinn EZM 13.1

The Sinn 6012 is a handsome, complicated chronograph featuring five dial-side complications, including a moon phase, built on a modified ETA 7751 movement. Reviewers note its clean dial offers good legibility, though one wished for a red accent on the date pointer. One long-time enthusiast considers the Frankfurt series, including the 6012, to be overpriced. The 14.5mm thickness makes it a slightly tall dress option. Overall, owners and reviewers find the Sinn 6012 to be a well-executed, complicated chronograph, with the primary reservation being its perceived value.

Owners widely praise the Sinn EZM 13.1 for its robust, tank-like build and purpose-built, rugged design with unique technological features. Some owners note accuracy averaging +6 to +8 seconds per day. One owner reported a misaligned hour hand, a stuttering chrono register in extreme cold, and discovered its case was not made by SUG. Owners are split on the watch's chunky nature and bracelet, with some finding it unsuitable. Overall, owners rate the Sinn EZM 13.1 highly for its unique, rugged design and robust build.
