When it comes to a statement watch, particularly one that's as durable as it is stylish, the watchmakers at G-SHOCK know no equal. Combining carbon fiber-reinforced resin — ensuring the case’s shock resistance while also reducing overall weight — with generously sized stainless steel buttons, the GSTB400 is not only the venerated brand’s slimmest timepiece ever, but it’s also an analogue watch that feels equally classic and futuristic. Add an opaque dial, attention-grabbing mirror finishes, smartphone connectivity and high-brightness readability (courtesy of the LED “Super Illuminator”), and you’ve got a handsome and utilitarian statement piece that can stand on its own this summer, from the city to the shore.
