Introduction
Famed for creating robust and functional watches that are crafted for professionals facing extreme conditions, the Sinn EZM1 Chronograph epitomizes the thoughtful design that has embodied the German watchmaker’s timepieces for decades. Showcasing the peak of mechanical durability it was launched publicly in 1997. While the various references within the EZM collection can lay claim to being designed for doctors, paramedics, and firefighters who require reliable performance in environments where a functioning watch could the difference in life or death, the EZM1 was designed specifically for German Customs Forces. Fitted with a black dual-hand chronograph dial with an offset date aperture, the EZM1’s display is tremendously unique thanks to its unusual design and red accents. Boasting a 41mm bead-blasted titanium destro-case, the EZM1 showcases that while Sinn might be best-known for pilot’s watches, they can make an incredible watch for specific groups like Customs Forces too.
