Technical information about this watch
Grand Seiko Heritage 37mm

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.

37mm 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.

Approx. 3 years 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.
