SINN U2 S
Boasting a case made of specially hardened submarine steel with a hard coating, this ticking jack-of-all-trades from Frankfurt am Main resists corrosion by saltwater and stays watertight to 2,000 meters. But that’s not all: Sinn’s own stay-dry technology relies on a sulfate capsule to effectively capture any moisture that might penetrate into the case as the years go by. Furthermore, tests conducted inside a climatic exposure cabinet guarantee that this 44-mm wristwatch functions perfectly at temperatures ranging from -45 to +80 degrees C (-49 to + 176 degrees F). The bracelet and case are equally well protected against scratches; the former culminates in a folding clasp with a divers’extension mechanism. Along with the time of day or night and the date, ETA’S self-winding Caliber 2893 also shows the time in a second time zone. Considering all you get for your money, $3,230 is a good price to pay.
