Nixon Sentry Chrono Watch All Black This is a very rugged & hardwearing watch that also looks the absolute business. The sleek super tough black stainless steel body is the perfect casing to protect the Miyota Japanese Quartz 6 Hand Chronograph movement, meaning the precision internals of this watch will stand up to most things you can throw at it. Keeping the watch attached securely to your arm is a 23-20mm 3 link stainless steel wristband with a micro adjust double locking clasp. This is one badboy of a watch that is just as functional whether you are wearing it out to dinner or wearing it for work. 24hr Subdial Hardened crown Custom molded hands 100m water resistant Description by Adam.
