Casio Analog-Digital GST-B400D-1AER

Product Information

Casio did a great job in reducing the size of the guards around the stainless steel buttons that are slim yet easy to operate. It makes the GST-B400 look less like an instrument. The top bezel shows no less than five different finishes, and the middle bezel has four different finishes. It sounds like a lot of decoration (and it is), but the result is subtle and brings a richness to a watch that is not only for the rich. Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. Introducing new color variations to the lineup of slim G-STEEL GST-B400 models with new, improved designs made possible by a thin module and carbon core guard structure. There is a standard model in this lineup, the GST-B400 with silver color face and resin band. I have a confession to make. When it comes to electronic watches with a gazillion functions, my mind goes blank. I’m not like a good friend of mine who practically lives for gadgets. He loves to try out everything, to dive deep into every single thing an electronic device can do. His Apple Watch holds no secrets from him. I, on the other hand, hate setting up electronic things. Think smartphones, TVs, laptops, and also electronic watches. I like my things mechanical. Mechanical watches, of course, but also other stuff that works with nuts and bolts and cogs and stuff. I love working on my racing bike, for instance. Changing the cassette, adjusting the gears, replacing the chain and cables, setting up the brakes — proper Zen stuff. When objects start bleeping when you touch them, I get grumpy. Technical amendments and errors excepted. The sizes in figures do not correspond to the original sizes.

After the Alert: The following operations are stopped to save power: all hand movement (excluding the day indicator), Bluetooth connection, if applicable, and alarmsThe button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. Invisible solar cells in the watch convert light into energy and supply all functions. A rechargeable battery provides the necessary capacity for operation in poor light conditions. The combination of stainless steel and carbon fiber reinforced resin supports the stability of the watch and provides a better wearing comfort. The GST-B400 is made possible by even further miniaturization of its parts and thinning of its modules without sacrificing any Bluetooth or solar function. Power consumption has also been significantly reduced.

The lower profile is a result of a newly designed module that is smaller with less components, combined with a high-density mounting with a flatter layout. With two analog hands, the Tough Solar-powered GST-B400 also consumes 55.7% less power than the GST-B200, and this allows for a new dial design with a metallic texture. For the GST-B400AD and GST-B400BD models, the dial is treated with a multilayer vapor deposition to create a vividly colored dial. The watch is equipped with energy-saving Bluetooth® technology, which offers power-saving data transfer at the push of a button. The watch can connect to a smartphone wirelessly via Bluetooth®, enabling access to a wide range of useful functions. Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810.The 49.6 mm case of the watch is made of stainless steel. The bezel of the model is made of stainless steel.
