The easy-to-read GNX 20 marine instrument display with black digits on a white or colour background clearly shows depth speed wind and 50-plus marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent daytime and night-time readability with high-contrast digits scalable up to 36 mm.

The GNX 20 is the first glass-bonded marine instrument with a combination of directly driven LCD segments and a dot-matrix field to display graphical information. Its low power consumption — (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight) — is perfect for use on sailboats and provides a valuable instrument for cruising and fishing. Fully customisable user profiles display wind depth and speed data. Plus the GNX 20 includes an auto-scroll feature that rotates through data screens for hands-free operation. It can be installed with the included low profile flush mount or an optional flat mount for the ultimate glass helm solution and custom look for your boat.

Great Value
I've been really happy with this watch. I like a bigger, "chunkier" watch, and I specifically did NOT want smart watch features. This is a great weekend and chores watch. I can beat it up, do work in it, and not worry about it. And surprisingly, it's been pretty bullet proof so far. Since I've worn a watch for almost my whole life, I barely notice when I have one on. And I am not precious about them at all. This watch has hit countless door frames, washed hundreds of dishes in hot water, scrapes against the wall, tools, yard equipment. It's been absolutely rock-steady and I haven't needed to adjust the time at all, other than for daylight savings. At the price, it's unbeatable.

Fantastic for the money
I use this watch at work, so about 40 hours a week I wear it. I work outside in a commonly rainy area, and it's not uncommon for the watch to get wet. I've had it for a couple months or so now, and it really works great! Honestly all of the complaints I have about it can be fixed solely by looking at the price. The viewing angle isn't fantastic - it's a $13 watch. It does lose a little bit of time (a second or two within a week, maybe) - it's a $13 watch. The band is a bit uncomfortable (though it does hold very well, and has lots of size options) - it's a $13 watch. Those are minor things. Here's the good stuff. -Super easy to read -Very easy to use and set -Multiple features -Is genuinely waterproof. I haven't held it underwater, or anything, but for what I would consider 'average' use, it is perfectly waterproof. -Has an adjustable band that doesn't fall off -Fairly tough. I don't treat mine very well and it's held up perfectly fine so far. -It's cheap!
