This model is based on the concept of colors found in nature and expresses a sense of comfort with nature. The base model is the GMD-S5600 which is a smaller and thinner version of the classic square design with an herb pattern printed on the dial. The bezel and band are made from biomass plastic which is expected to contribute to reducing environmental impact by using renewable organic resources such as corn as raw materials. With gentle colors and design expressions inspired by nature this watch is perfect for those who prefer a slow lifestyle. ・ Shockproof structure・ 20 ATM waterproof function・ Stopwatch (1/100 second (00000 to 595999)/1 second (1:000 to 23:5959) 24 hour meter with split) - Timer (set unit: 1 second maximum set: 24 hours measures in 1 second increments auto-repeat)・Multi-alarm・Time signal・Full auto calendar・12/24 hour display switching・LED backlight (with super illuminator and afterglow function)・Sound flash function (alarm/hourly signal/timer sound linked light emission)・Battery life approximately 3 years
