Review: Great watch for wife - My wife wanted another G shock but she doesn't like Baby G shocks and she wanted something that was fitting for her work place. She saw these come out and she liked the black one. I bought it as a gift and it 100% met her expectations. It's a good size for a small wrist. It doesn't say Baby G on it which is a turn off for some people. The black is a nice shade for a clean look and the rose gold like accents give the watch a little something so it fits in well in a work environment and jewelry coordination. If it was like the all black larger version it would be too tacti-cool for some settings. It's super light and it reads well. This watch definitely fulfills every bit of its specs, advertising and online appearance. Sometimes it's hard to tell how a watch will look in person and on the wrist but this one was spot on. If you are liking it but are unsure, spring for it. It meets the hype, and some. ## Features - From Casio G-Shock, this new GMAS2100 watch is a downsized version of the GA-2100 model - It is slim, lightweight, and compact in design and boasts a chic, monochromatic look ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08ZDPZZFP | | Additional Features | Shock Resistant, Timer, World Time, light, stop-watch | | Age Range Description | Adult | | Band Color | Black | | Band Material Type | Resin | | Band Width | 24 | | Bands | 1 | | Best Sellers Rank | #622,296 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #1,835 in Women's Wrist Watches | | Brand Name | G-Shock | | Case Diameter | 42 Millimeters | | Case Material Type | Carbon/Resin | | Case Thickness | 11 Millimeters | | Character | fashion | | Clasp Type | Buckle | | Clasp type | Buckle | | Closure Type | Buckle | | Crystal | mineral | | Customer Reviews | 4.3 out of 5 stars 251 Reviews | | Dial Color | Black | | Display | Analog-Digital | | Embellishment Feature | Crystal | | Face Style | Crosshair (possible other styles: Teaked, Linen) | | Gem type | Not known | | Included Components | Band | | Item Type Name | Sport Watch | | Item type name | Sport Watch | | Item width | 5 inches | | Manufacturer | G-Shock | | Manufacturer Part Number | GMAS2100-1A | | Metal type | Black Gold | | Model Name | Casio G Shock | | Model Number | GMAS2100-1A | | Pattern | Solid | | Power Source | Battery Powered | | Series Number | 2100 | | Shape | Octagonal | | Sport Type | Multi-Sport | | Strap Type | Two Piece Strap | | Style Name | Watches | | Theme | Sports | | UPC | 889232300252 | | Unit Count | 1 Count | | Warranty Type | Manufacturer | | Watch Movement Type | Japanese Quartz | | Water Resistance Depth | 30 Meters | | Water Resistance Level | Water Resistant | ## Images ![GMAS2100-1A - Image 1](https://m.media-amazon.com/images/I/81t1YBvN-sL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ G-shock with style. *by A***R on March 5, 2026* It is an elegant G-Shock, nothing fancy but it has its own style for sure. ### ⭐⭐⭐⭐⭐ Great watch for wife *by A***Y on July 14, 2021* My wife wanted another G shock but she doesn't like Baby G shocks and she wanted something that was fitting for her work place.
