        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.

        Excellent service from an excellent company. Phoned a couple of days before order would arrive and was reassured of my delivery date, as I would be out if the country. 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.
