It combines the classical proportions and double-signed dial of the pre-2017 era with the modern 9S66 mechanical GMT movement and several details created specifically for the 10th-anniversary edition.\u003c\/p\u003e\n\u003cp\u003eIts dial is undoubtedly the highlight. The combination of deep royal blue with warm gold markers and GMT hand creates a color scheme rarely seen among Grand Seiko’s standard-production mechanical GMTs, and the true depth and saturation of the blue is exceptionally difficult to reproduce accurately through photographs.\u003c\/p\u003e\n\u003cp\u003eThe blue anniversary rotor also makes the SBGM031 immediately recognizable from the caseback, while its 39.5mm diameter gives it exceptionally wearable proportions. With production limited to 1,000 examples worldwide, it remains a considerably less common and collectible alternative to Grand Seiko’s regular-production GMT models.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"JDM Horologist","offers":[{"title":"Default Title","offer_id":50982451478771,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/4984\/1907\/files\/wts-jdm-sbgm031-2012-grand-seiko-10th-gmt-anniversary-le-v0-dfq77m0dzfqe1.webp?v=1788701418","url":"https:\/\/jdmhorologist.net\/products\/grand-seiko-sbgm031-royal-blue-limited-edition","provider":"JDM Horologist","version":"1.0","type":"link"}
