In chic monochromatic black and gray, the MTG-B3000B features a soft urethane band.
This innovative, tough new style delivers full-on functionality, as well. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®. With Multi Band 6, Tough Solar charging system, and high-brightness LED light, this timepiece keeps you at peak performance, whatever your adventures may bring.
Combining rigidy, compact form, and lightness:
An even more advanced Dual Core Guard structure
We continue to improve our original MT-G Dual Core Guard structure, now protecting the module with a carbon-reinforced resin case and enclosing the exterior with metal components.
At the heart of the new structure is the unique case back, a solid piece of intricately shaped stainless steel. We give it high rigidity using integrated moulding to create a single form with raised sides, which serves as the lugs to secure the band and as the guards for crown and buttons.
Intricate metal exterior
for a totaly unique beauty of a form
We apply repeated processes of pressing, cutting, and polishing to make a stainless steel case back that is smooth on the wrist but protrudes upward in an intricate, 3D form.
Its configuration interlocks with the top bezel, with uniquely shaped screws joining the two.
With its stunning Sallaz-polished surfaces and intricate beauty of form, this timepiece shows off the profound look of the metal material itself, while also achieving a slim profile.
Advanced functionalty in dowsized form:
A slim, shock-resistant module
While maintaining shock resistance, we optimised the circuit board layout by using smaller, slimmer parts and integrating electronic componentry with high-density mounting technology.
This multi-hand chronograph is equipped with Smartphone Link and solar-powered radio control, but with a module 1.45 mm slimmer than the MTG-B1000.
That makes the watch more than 2 mm slimmer, at just 12.1 mm.
One-touch exchange for easy swapping
Simply press buttons located on both sides of the lugs to quickly and easily swap out the band without special tools. Fun customisation options are provided with two interchangeable bands: a layered-composite band made of hollow metal segments encasing fine resin parts, and a soft urethane band with a light, comfortable fit.
Black accented with distinctive and colourful IP
Ion plating (IP) in options of red or green provides vibrant accents to the bold black base colour. The MTG-B3000B features a monochrome black and grey appearance.
Super Illuminator
Super Illuminator (high-brightness LED light) for maintaining watch readability in the dark
Solar-powered

-
Solar Power
A solar cell provides power for operation
-
Auto-Hand Location
Using an LED, the positions of the hour, minute and second hands are checked at the 55'00" of every hour to ensure correct hand positioning. If the hand time does not coincide with the counter within the IC, the movement corrects the hand position automatically
-
LED Light (Super Illuminator)
A light emitting diode is used to illuminate the face/display. Super Illuminator uses high-brightness LED for easier reading
-
World Time (R27)
Displays the current time in major cities and specific areas around the world. R: Current time in major cities around the world. Values indicate number of cities/areas
-
Beeper Alarm
Beeper tone alarm sounds at the time you set
-
Stopwatch (24HR)
Accurate measurement of elapsed time with the touch of a button. The fraction indicates the unit of measurement, while the time figure indicates the maximum time measurement
-
Timer (24H)
Counts down from a start time specified by you. The value indicates the number of timers available, while the time figure indicates the maximum starting time. “REPEAT” indicates Auto Repeat, which automatically restarts timing at the end of each countdown
-
Full Auto-Calendar
Allowances are made automatically for months of different lengths, including leap year
-
12/24-Hour Timekeeping
Times can be displayed in either 12-hour or 24-hour format
-
Battery Level Indicator
Indicator shows the current battery level
-
Triple G-Shock Resistant

-
Neobrite
A luminous coating provides long-term illumination in the dark after only short exposure to light
-
Water Resistant (20 BAR)
The “BAR” value indicates the number of atmospheres to which water resistance is ensured. 20 BAR means water resistance to 20 atmospheres. Watches marked “200m” have the same water resistance as 20 BAR watches
