Technical information about this watch

Grand Seiko Heritage 30mm

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.

It features components crafted with advanced MEMS engineering, including the pallet fork and escapement wheel, while the balance spring is made from the latest Spron alloy. With a mean daily rate of +8 to –3 seconds, a 50-hour power reserve, and 35 jewels, it beats at 28,800 vibrations per hour and includes a date display—combining precision, durability, and elegant design.

30mm 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.

50 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.
