What is the Grand Seiko SLGC007 Tentagraph?
The SLGC007 is a mechanical chronograph in Grand Seiko’s Evolution 9 collection. Grand Seiko calls it Tentagraph and describes the dial as snow blue, inspired by Mount Iwate in winter. The name refers to four features of its movement: ten beats per second, three days of power reserve, automatic winding, and chronograph. (Grand Seiko product page)
The dial’s chronograph display includes 30-minute and 12-hour counters. The watch also has a date display and tachymeter scale. Its exterior pairs a high-intensity titanium case with a ceramic bezel, a see-through screw case back, and a box-shaped sapphire crystal with anti-reflective coating on the inner surface. Grand Seiko lists luminous hands and indexes.
What movement is in the SLGC007?
It uses Grand Seiko Caliber 9SC5, a self-winding movement that can also be wound manually. The movement has 60 jewels and beats at 10 times per second. Its approximately 72-hour reserve—three days—remains the same when the chronograph is running, according to Grand Seiko. (Grand Seiko specifications; Grand Seiko on the Tentagraph name and movement)

How big is the Grand Seiko Tentagraph?
Grand Seiko lists the SLGC007 at 43.2 mm in diameter, 51.5 mm lug-to-lug, and 15.3 mm thick. The band width is 23 mm, and the listed weight is 154 g. Those measurements describe a substantial chronograph; diameter alone does not convey its full footprint, so lug-to-lug length and thickness are useful figures to consider when judging fit. The case is high-intensity titanium, while the bezel is ceramic. (Grand Seiko product page)
Water resistance and accuracy
The SLGC007 is rated to 10 bar water resistance. Grand Seiko also lists a screw-down crown and magnetic resistance of 4,800 A/m. These are manufacturer specifications, not a substitute for checking the watch’s condition or following care guidance before exposing a particular example to water. (Grand Seiko product page)

Grand Seiko publishes two different accuracy ranges, each tied to different conditions:
- Movement before casing: mean daily rate of +5 to −3 seconds per day, measured over 12 days in six positions under controlled conditions.
- Normal use: stated accuracy of +8 to −1 seconds per day.
The controlled movement test and normal-use figure should not be treated as interchangeable guarantees for every worn watch. (Grand Seiko product page)

What to compare before choosing a chronograph
For a useful comparison with another chronograph, look beyond the movement name. Check case dimensions and thickness, case and bracelet materials and weight, the movement’s reserve with the chronograph engaged, counter layout and timing function, water resistance, and the local price. Compare accuracy only when the quoted figures use comparable test conditions.
