This versatile Spring Drive GMT is designed for any setting—from the boardroom to weekend adventures—yet its soul is rooted in the misty mountains of Nagano. The softly textured dial captures the serene atmosphere of morning fog blanketing the peaks in winter, a tribute to the region where Spring Drive was born. Crafted from high-intensity titanium, the case is 30% lighter than stainless steel for exceptional comfort. The Spring Drive Caliber 9R66 powers a smooth-gliding seconds hand, a GMT function for tracking a second time zone, and a 72-hour power reserve. With 10 bar water resistance, a sapphire crystal with inner AR coating, and a see-through case back, it’s refined, resilient, and ready for anything.

Technical information about this watch
Grand Seiko Evolution 9 "Mistflake" 41mm

100M / 10 ATM water resistance
Water resistance indicates a watch's ability to withstand moisture and water. Ratings are measured in metres (M) or atmospheres (ATM). For instance, 30M (3 ATM) is suitable for light splashes, while 100M (10 ATM) and above are ideal for swimming and diving. Regular maintenance helps retain water resistance over time.

41mm case size
Case size, measured in millimetres (mm), impacts the watch's look and fit. Men's watches typically range from 38mm to 46mm, and women's from 26mm to 36mm. Larger cases make a bold statement, while smaller cases offer a classic look. Choosing the right size ensures comfort and style.

72 hours power reserve
Power reserve is the duration a watch runs on a full wind or charge. Mechanical watches usually offer 40 to 80 hours, with some extending to several days. Quartz watches, powered by batteries, last several years. Knowing the power reserve helps maintain accurate timekeeping.
