The shadow caused by the cutting is used as the time scale to accurately indicate every minute and second. The concrete grid rises slightly in the “22nd” minute, echoing our brand name, along with the subtle tacit understanding that only the wearer knows. Field Edition Suitable for the popular Urban Outdoor style. The case itself can be regarded as a blackened cement grey model. The dark grey to black gradation shows the overall design lines.
