The G-Shock 2100 Series GA-B2100LUU-8AER men's watch is an offering with a Japanese quartz movement, distinguished by its gray colored envelope and plastic strap. The watch offers a number of advanced amenities: 5 daily alarms, a perpetual calendar and a day-of-the-week indicator (with a choice of six languages). The watch's practicality is enhanced by the Hand Shift function, which pushes back the hands so they don't obstruct the digital displays, and a battery level indicator. The model also has a Mute function for muting the sound of the buttons. Water resistance of 200 meters makes this watch fully suitable for intensive contact with water, including swimming and diving.

Reviews about G-SHOCK Urban Utility GA-B2100LUU-8AER (6)
This model is an absolute hit and instantly won me over with its "concrete" finish. The gray shade looks incredibly professional in person and goes with literally everything, from a hoodie to a more casual shirt. I’m thrilled by how light it feels on the wrist, even though you can still feel that signature G-SHOCK sturdiness. The hand-slide function is a brilliant solution, because everything on the digital display is legible in a split second. Shopping at Zegarownia was a pure pleasure; the express delivery meant I could enjoy my new purchase the very next day.

I received this watch as a gift and liked it right away. It’s a sturdy model that combines a modern look with durability. It goes well with many styles, and its design is really well done. I definitely recommend this product to others.

I bought this watch for my boyfriend for Valentine's Day. He really liked the gray plastic strap—it's comfortable and practical. It's a really cool product.
