G-SHOCK releases the latest GM-B2100 for the first time in yellow-gold
A new colour option for the GM-B2100 series with the octagonal metal bezel
Norderstedt, 21 February 2023 — G-SHOCK today announced the release of the new GM-B2100 in yellow-gold. The new GM-B2100GD-9AER features a full-metal design with the dominant octagonal bezel and boasts an impressive new yellow-gold hue.
First released in 2019, the iconic brand's 2100 line watch—the GA-2100 digital-analogue combo model—presents another interpretation of the very first G-SHOCK. Known for its distinctive octagonal bezel and sleek, simple design, the line has gained immense popularity worldwide. G-SHOCK has consistently developed the collection, such as with the GM-B2100, where the external components such as the bezel, strap and case are made of stainless steel.
The new GM-B2100GD-9AER is a robust watch that comes in a distinctive yellow-gold hue, offering another colour option for the GM-B2100 models. The IP finish is used on the bezel and strap, as well as on smaller design elements, such as the side buttons and screws. The appliqués on the top of the bezel and the high-gloss beveled sides enhance the textural look of the radiant metal.
Accents in a modified yellow-gold further emphasize components such as indexes and hands. They stand out from the black dial and give the watch an elegant look. Casual or formal, the versatile design can be paired with any outfit. The new colour scheme emphasizes the subtle and distinctive character of this watch.
The new G-SHOCK also offers a practical benefit with Tough Solar technology, which eliminates the need for regular battery replacement. In addition, the model is equipped with Bluetooth®. The connection to the smartphone via the new CASIO WATCHES app* ensures accurate time display and allows access to many other functions such as countdown timer, phone finder, world time and alarm, among others.
The GM-B2100GD-9AER has the following features, among others:
- Tough Solar technology
- Bluetooth®
- Shock-resistant
- Water-resistant to 20 bar
- Stopwatch
- Five alarms + countdown timer
- Automatic calendar

The GM-B2100GD-9AER model will be available from April 2023 at gshock.casio.com/de for an MSRP of €599.00.

About G-SHOCK
G-SHOCK was born from the idea and desire to create an indestructible watch. CASIO's engineers followed the "Triple 10" concept, which included making sure the watch could survive a 10-meter drop, withstand 10 bars of water pressure, and last 10 years on a single battery. Since its launch in 1983, G-SHOCK has stuck to this concept and continued to perfect the G-SHOCK models through development. The cult brand made a name for itself worldwide in the fields of fashion, sports and music. As a testament to this success, G-SHOCK is celebrating its 40th anniversary this year.
