CASIO Casio G-SHOCK GM-S2100B-8AJF

[Product features]
This model uses metal material from the GA-2100 series, which inherits the octagonal form that was also used in G-SHOCK's first model, DW-5000C.
Among the GA-2100 series, the GMA-S2100 is based on the GMA-S2100, which has been thoroughly made compact and thin to fit any occasion, and the bezel cover uses hard stainless steel material to improve the texture. The hairline process along the circumference of the dial expresses the shading of the IP process on the bezel. Additionally, the flat dial is also vapor-deposited, giving it a stylish look. Furthermore, the indexes are mirrored to add a touch of glamor. It is a stylish model that maintains the concept inherited from the first generation, but pursues the quality of a watch and has refined its exterior and wearability.
