Why Choose "G-Shock"

G-Shock, created by Casio in 1983, was the brainchild of engineer Kikuo Ibe, who aimed to design an unbreakable watch. The result was the DW-5000C, featuring a shock-resistant structure, 200-meter water resistance, and unparalleled durability. G-Shock quickly became popular for its toughness, functionality, and bold design, appealing to athletes, military personnel, and adventurers. Over the years, the brand introduced advanced features like solar power, Bluetooth connectivity, and GPS. Celebrated for its innovation and resilience, G-Shock remains a global icon, known for watches that are “built to last.”

An ultra-thin module  encased in carbon fiber makes for a stylish G-STEEL timepiece with the slimmest profile yet.

Strong, yet lightweight, the carbon core guard structure absorbs external shocks and retains Bluetooth connectivity and solar power functionality even with smaller components and a thinner module. Measuring just 12.9mm from the back of the case to the top of the bezel, the GST-B400 is over a millimeter thinner than its predecessor .

Your choice of four distinctive styles—the simplicity of a silver metal band and silver case; light silver case set against dark resin band; dial in dramatic red vapor deposition finish paired with a black ion-plated bezel; or dial in bold blue vapor deposition finish with black ion-plated bezel and band. With top bezels treated with five different finishes and middle bezels treated with four, these G-STEEL timepieces deliver exceptional metal textures from every angle.

Was hunting for a Seiko astron for a while. Found this place listed as an authorized dealer and decided to look around. Moe was great, not only did he have them, he pulled out all of the stock in the back for me to look at and pick from. I ended up with a limited edition 50th anniversary astron. Super happy with the purchase. 10/10 service, I’ll be back!

Was walking around Menlo Park Mall and saw some posters outside this Jewelry Store that piqued my interest so I walked in and was greeted by really kind and knowledgeable staff. Ended up getting something I wanted for a while thats hard to find in stock at most places, but they had it available and offered me a great deal for it too! Definitely check this place out, nice inventory, nice staff, and family run business!
