The popular iconic style "YRA series" has appeared in G-SHOCK's FINE METALLIC SERIES (GM series). This time we will introduceGM-2100YRA-8ADRis a metal bezel model based on GA-2100.
A stainless steel bezel with a combination of hairline and mirror finishes, and a dial with a contrast of silver and red—a calm octagonal form with a vibrant personality. The combination with a slide band made of fabric material combines the hardness of metal with the softness of textile, and is a new proposal for G-Shock that can become a fashion statement.
GM-6900YRA-8DR and GM-5600YRA-8DR are also available in the same YRA series, and while they share the same design direction, they each have different forms. For those who are worried about which G-Shock to choose, a fun approach is to compare the YRA series lineup.

■ “GM series aesthetics” called FINE METALLIC SERIES
What sets G-SHOCK's GM series (FINE METALLIC SERIES) apart from other G-Shocks is the use of stainless steel for the bezel. The GM-2100YRA-8ADR uses a two-sided configuration with a hairline finish on the top of the bezel and a mirror-polished finish on the slope. The design changes between the subdued luster of the hairline and the sharp shine of the mirror depending on the angle at which the light hits it, creating a new look each time you turn the watch.
The thin octagonal form that characterizes the GA-2100 series gives it a more three-dimensional and sharp impression with the stainless steel bezel. This approach, which combines the lightness of a resin case with the texture of stainless steel, is one of the reasons why the GM series has been supported for many years.
■ G-Shock's new proposal of fabric slide band
The fabric slide band used in the GM-2100YRA-8ADR band is designed to combine the soft texture unique to textile materials with the ease of use provided by the sliding adjustment mechanism. The texture and visuals are different from regular urethane bands, making G-Shock stand out as a fashion item.
Combined with the dial color, which has a strong contrast of silver and red, the overall style of ``G-Shock that looks good on the street'' is completed. Not only can it be matched with sportswear, but it also blends naturally with casual street style.
■ Comparison of 3 YRA series models—Select by form
The YRA series has three models: GM-2100YRA-8ADR (GA-2100 base octagon), GM-6900YRA-8DR (6900 base round), and GM-5600YRA-8DR (5600 base square). Although the coloring concept is the same, each form fully demonstrates its individuality. The natural approach is to choose which G-Shock series you prefer.
The GM-2100 base follows the thin octagonal form known as the GA-2100 (commonly known as "CasiOak") and is the slimmest and most modern of the three models. It stands out for its comfortable feel when placed on your arm and its well-balanced appearance.

■ Buyer's comment
I think the GM-2100YRA-8ADR is the one with the highest degree of perfection in the context of ``enjoying G-Shock as fashion''. The hairline and mirror finish of the stainless steel bezel is quite exquisite when you look at it in real life, and it goes perfectly with the contrast of the silver and red dial. The addition of a fabric slide band creates a different "hand look" than other G-Shocks. The three models in the YRA series each have their own unique characteristics and are fun to choose from, but I feel that the slim octagonal shape of the GM-2100 is the most "modern".
