From the MASTER OF G Series MUDMASTER, the watch that is designed and engineered to withstand rough land environments, come carbon resin models that incorporate a new type of structure.

The case is made of high-rigidity carbon material to protect against damage and deformation due to impact and other rough treatment, while metal button pipes ensure a tighter seal against the external environment. A filter further protects against the invasion of mud, for the high level of dust and mud resistance required when in severe environments. In addition, the dual back cover consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers. The bezel is formed of three layers of fine resin with carbon fiber inserts. The top layer is transparent, resulting in a bezel that shows the embedded carbon material.

Quad Sensor capabilities use compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurements, along with an accelerometer that keeps track of your step count, into a compact configuration. This provides the outdoor adventurer with the means to keep track of the surrounding environment while on the go.

A special G-SHOCK app, which simplifies configuration of watch settings, also includes a new Mission Function. The app automatically records altitude data measured by the watch and route information acquired by a smartphone's GPS. Manually obtained altitude points can be plotted on your route. Altitude measurement and the step count are used to perform consumed calorie calculations that take up and down grades into consideration, and to record the results in an activity log.

A watch button operation can be used to record your current location with the app. Then the second hand indicates the bearing to the recorded location, while the digital display shows the distance to the location.

These new models also support Mode Switching Customization. You can use the app to enable or disable modes individually so only enabled modes appear. You can even specify the sequence to be used when displaying the modes.

Best Sandal Ever
There is nothing about these that I don't LOVE. These are so comfortable and look so good. I have 6 pairs in every color. They r my absolute favorite. Run true to size. Listen to Amazon about sizing. They know... I am between size 7 and 7.5 and they recommended 7 and it was a perfect fit. I have not had any issues with the Velcro closure. Amazon has the best prices for UGGS.

Sandals that go with just about everything.
As a lover of everything Ugg, these didn't disappoint. They are some of the most comfortable shoes I have, very lightweight, and go with just about everything. They remind me of the old school Dr. Martens and I had a massive collection of those in high school. I have worn them quite a bit and you can barely tell as they are holding up extremely well.

Cute and comfortable!
Size: 6.5, Color: Chestnut
These are cute and surprisingly comfortable! My arches feel supported and the soles don’t feel as block-like as other platform style sandals! Things to note: The footbed liner is not made of suede and is a little slippery. It’s like a neoprene liner which was unexpected for an Ugg shoe. Also, I only intend to wear these sandals as slides (a la Birkenstocks) so the “adjustable” Velcro strap over the top part of the foot seems useless. It doesn’t snug the top down at all, functionally speaking it is only to wear around the back of the ankle. Maybe this matters to someone thinking they could tighten the top down a bit. The ankle strap is comfortable but could be a bit longer. Overall they are a cute option to the platform Birks that are very uncomfortable imo. Love the options to order half sizes. I’m usually a 6 in Ugg boots but ordered my regular shoe size 6.5 and they fit well. My heel would be at the very end of my sandal if I sized down. True to size. Keeping and will order in another color!
