Grand Seiko’s published dimensions are 40.0 mm across, 47.2 mm lug-to-lug and 11.7 mm thick. Its official regional listings show USD 9,700 on the Middle East page and ¥1,342,000 including tax on the Japan page; neither figure is a universal price.
This is a specifications and price overview based on Grand Seiko’s published information, not a firsthand hands-on review. The listed figures do not establish how the watch wears, performs on an owner’s wrist or appears in changing light.
What is the Grand Seiko SLGH013?
Grand Seiko identifies the SLGH013 as a Heritage Collection Hi-Beat 36000 80 Hours model and describes it as a new 44GS design. The brand says the original 44GS dates to 1967 and defined the Grand Seiko Style. Grand Seiko’s Middle East product page and its US Heritage Collection overview provide those descriptions.
The light-blue dial’s texture is inspired, according to Grand Seiko, by snow beginning to melt in spring on Mt. Iwate, the peak overlooking Grand Seiko Studio Shizukuishi. That is the manufacturer’s explanation of the design inspiration, rather than an independent assessment of the dial.

Grand Seiko describes the dial as flat with a wide opening, and highlights faceted indexes and hands. The index at 12 o’clock is twice the width of the others. The company also describes Zaratsu polishing on the case’s upper surfaces and reports a PREN above 40 as a corrosion-resistance measure for Ever-Brilliant Steel. These are manufacturer descriptions and specifications, not independently verified performance findings. See the official SLGH013 page.

How to interpret the SLGH013 accuracy figures
The two accuracy figures on Grand Seiko’s product page describe different things. The mean daily rate of +5 to -3 seconds per day is measured before the movement is assembled into a case: Grand Seiko says the test uses six positions, controlled conditions and a 12-day period. It should not be read as a guaranteed result on the wrist.
The page separately gives normal-usage accuracy as +8 to -1 seconds per day. That is the manufacturer’s stated range; the published specifications do not establish the result for a particular wearer or an individual watch.

Grand Seiko SLGH013 price by region
Grand Seiko’s regional pages list different market-specific prices. The Middle East page lists USD 9,700 and says the model is available at Grand Seiko Boutiques and Grand Seiko Salons. Grand Seiko Japan lists ¥1,342,000 including tax and provides a boutique-online purchase route. These are regional listings, not a currency-converted global MSRP. Tax treatment, retailer access and stock can vary, and listed prices or availability may change. Check the relevant market page for current details: Middle East and Japan.
SLGH013 wrist size and strap fit
The published case measurements—40.0 mm diameter, 47.2 mm lug-to-lug and 11.7 mm thickness—are useful comparison points when assessing whether the SLGH013’s dimensions suit your wrist. They cannot establish wrist presence or comfort; those depend on the wearer and are not documented by the manufacturer specifications.
Grand Seiko lists a 19 mm band width. Its Japan page also lists an official 19 mm RG03W19BL crocodile strap at ¥41,800 including tax. That listing confirms a manufacturer strap option, not compatibility of every third-party strap: width alone does not establish that an end link or clasp will fit. Check the regional listing for the current strap details at Grand Seiko Japan.
