The first watch in the popular 2100 line to be included in the flagship Casio G-SHOCK MR-G family, the titanium MRG-B2100B-1A watch takes inspiration from kigumi—the ancient Japanese art of interconnected wooden construction without the use of nails—by utilizing this design inspiration for more than just style. True to the ancient art, form meets function: Casio designed this titanium watch with 27 separate components in the bezel alone, inserting buffering materials between the components as part of the tough Multi-Guard Structure. The hour indices are formed by two watch face components, adding further sophistication to honor the ancient Japanese art.
Precision excellence in design, beauty, and materials, the G-SHOCK MRG-B2100B-1A titanium watch is a study in watch making. Elegance and sophistication are the hallmarks of the mirror-finish black sheen and the kigumi-inspired latticework design of the face and construction of the bezel and indices. That elegance and sophistication are complemented by legendary G-SHOCK toughness with the boost of titanium metals, including the titanium alloy Ti64, an alloy used in the aerospace industry and for biomedical applications.
Precision, toughness, and beauty are the guiding design factors for the G-SHOCK MR-G family of flagship watches, and the attention to detail behind the design and construction of the MRG-B2100B-1A titanium watch ups the ante for the MR-G line. The top of the bezel is made of Cobarion®, a titanium alloy four times harder than pure titanium that also offers a white gleam like that of platinum. The watch band is fashioned from DAT55G, a super-hard titanium alloy that offers excellent processability, ensuring a comfortable fit.
Scratch resistance is a core component of Casio’s titanium watches. Diamond-like carbon coating enshrouds the titanium, and the sapphire crystal glass ensures the MRG-B2100B-1A titanium watch is scratch resistant to the highest levels of modern technology and design. The coatings are hand finished by master artisans, giving an artful and precise completion to a titanium watch inspired by an ancient Japanese art of craftsmanship and beauty.
The design and style may be influenced by an ancient artform, but the technology is wholly modern. The G-SHOCK MRG-B2100B-1A titanium watch is calibrated daily by a radio signal or through Bluetooth® connectivity, ensuring accurate timekeeping. Add in Tough Solar power charging and both magnetic resistance and 200m water resistance (wr 20 bar), and this titanium G-SHOCK watch is as reliable as a sunrise.

I had such a great experience with Time Machine Plus! I had a situation where I needed to call customer service to try and expedite shipping and they were EXTREMELY helpful-not only did I get the watch in time, it came with three days to spare!
I received the watch today and it is perfect; the packaging was incredible so no need to worry about any damage in transit. I cant say enough good things about my experience with Time Machine Plus, all the way around. 100% recommend 👍👍
Excellent features for the price. Looks better in person than in the photographs.
Excellent pricing and fast, efficient delivery.
Outstanding process all around from initial commo to delivery
Outstanding purchase, communication was flawless, fast shipping and packaged to protect my new watch. Excited to have a Longines AD I can trust!
OUTSTANDING CUSTOMER SERVICE
Great communication and price. Were very fast to respond to my emails and met my specific requests for this purchase. Peace of mind to buy from an authorized dealer and receive the longines 5 yr warranty. Buy with confidence.
Great company to work with, they go above and beyond to make sure their customer is taken care of.

Very nicely made watch with a nice leather strap and watch. The dial in the teal color is great. I initially bought that color the turtle conservation but it grew on me. In an all black outfit, the teal is a nice accept while the hour marks and hands glow in the dark. I love it!
Amazing
Absolute seamless transaction! Fast communication, shipped promptly, will gladly purchase from again.
Great watch!!! Love the design and precision! Shipping was immediate!! Highly recommend Time Machine Plus
The watch is great; is everything I expected from watching numerous YouTube videos and reading reviews from trusted independent sites. More importantly is the service from Time Machine. This is my SECOND purchase from them and they didn’t disappoint; although the watch appeared on their site several weeks earlier it was not on the site because it was sold out. I called, an order was placed and at a great price. Consistency is appreciated! How many times have you dealt with a business and the first experience was positive and later not so much? This review is not intended to be or sound in any way hyperbolic. Too often if something or someone sounds too good to be true it turns out that way; not so here and that is the reason for the seeming rave; because they are the exception.
Great field watch, comfortable, and the green dial looks beautiful. The 38mm model is the perfect size.
