Definitely interesting design Definitely interesting design. But when using it's disappointing. The watch buckle adjusts poorly, squeals like an old bicycle chain, and gives you a constant discomfort by pulling out your hand hair.

Great quality belt! Great quality belt, arrived well-packaged too!

The standard of watch The standard of watch, battery life, customer service - all poor. THE BIGGEST ISSUE IS BATTERY LIFE - IT USED UP NEARLY 75% OF BATTERY POWER JUST OVERNIGHT WHILST SLEEPING. I think this is my 2nd or 3rd replacement and still having issues with charging points going rusty green - plus the charging points are hot when you put on wrist. Look elsewhere if you want to buy a watch - Suunto or Garmin for waterproof outside stuff.

Can't see the hands The hands on The Sentry are hollow, sort of like wire frames, not solid. So it's almost impossible to see them (so to see where they are pointing). In bright daylight or bright artificial light, you have to move your arm/wrist around until the light catches the thin-framed hands. In low light, fine. So think carefully, if you want to tell the time instantly, you won't be able to most of the (bright) time. All but renders the watch useless, or at best very frustrating. Silly design.

The quality is just not there The quality is just not there. I’ve had 3 watches all have issues, Nixon refuses to fix them as they’re “discontinued” (only 2 years old!!) and only offers a measly amount to buy a new watch. It’s an absolute joke, they’re a massive disappointment sadly. Spend your money elsewhere on a quality brand that stands behind their product. This however, is cheap garbage that is not stood behind.
