Technical information about this watch

Grand Seiko Heritage 40mm

A water resistance icon in the shape of a shield. On the shield is a drop of water and beside the water are two lines that looks like waves.

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.

A watch movement icon display the inside gears of a mechanical watch.

GS Calibre 9R65 Spring drive automatic winding

Caliber 9R65 is the most widely used movement in the 9R Spring Drive series, known for its precision, durability, and reliability. Although the first Spring Drive watch launched in 1999, it took four more years of development to create a version that met Grand Seiko’s standards. The result was an upgrade from manual winding with a 48-hour reserve to an automatic system with a 72-hour reserve, powered by an enhanced Magic Lever mechanism for improved efficiency and durability. It offers ±1 second per day accuracy, along with a power reserve indicator and date display.

40mm 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.

A power reserve icon that looks like a gauge that indicates how much power is left.

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.
