    A real sports and smart watch. Easy to operate with a clear and readable face. The controls are well positioned and work well when wearing gloves for cycling and running. Price is very affordable and it looks good, is light and the perfect watch for either sport or in the office. Highly recommended.

    Just received this model today, it’s my 2nd Gravity Master and I love it. The photos both here and online do not do this watch enough justice, it’s a piece of work and its detailing & spec for the price is superb. Even at full retail, it’s worth every penny... it has a “high end” G-Shock feel with it's build quality & superb functionality and all without the “high end” price tag. The app via Bluetooth regarding setup is so intuitive & easy to use and you’ll have this watch setup in a matter of minutes. If you’re “old skool” and choose to set it up manually, that’s equally as easy... typical Casio format with little or no need for the manual if you’re familiar with the menus. Not only is the lume good but the backlight is quite possibly the best on any G-Shock I’ve seen to date... the analogue lights up nicely but what really stands out is the brightness and legibility of the dot matrix LCD display. Don’t be put off by the size of this watch either, it sits very ergonomically around the wrist and with very little weight given the “Mudmaster” style strap. This watch allied to the great service from FIRSTCLASS WATCHES has made the entire purchase a most pleasurable experience.

My G-Shock B100 Gravity Master is perfect for my work, travelling at almost the speed of sound, the perfect timepiece for my needs. Thanks for a first class experience from First Class Watches.
