Applied baton markers keep the look sharp and uncluttered, while the clean date window at 3 o’clock integrates seamlessly into the overall design. While some 61GS models were offered with both day and date, this configuration keeps things focused and balanced.\u003cbr\u003eThe date can be quickset via the knurled crown, signed with the GS logo, a small but satisfying detail. Slim dauphine hands, each defined by a fine black line down the centre, add contrast and precision, completing a dial that feels both refined and highly legible.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe movement is one of Seiko’s finest, a 25-jewel automatic hi-beat that operates at 36,000bph, made at their Suwa factory. It can also be wound manually and has a hacking feature. It is finished to a high level, with a nicely decorated rotor. The 61GS movement achieved the Seiko internal GS standard approval, which was adjusted to be within -3\/+6 seconds per day when it left the factory. It is based on the 61 SeikoMatic 5 movement and was engineered with technology developed from data from the Astronomical Observatory Concours competitions that Seiko did extremely well in during the late 1960s.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eA BIT OF TRIVIA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe Grand Seiko line made its debut in 1960, and continued until the 1970s (the mechanical Grand Seiko was revived in 1998 and continues production to this day). The most iconic of all the Grand Seiko case designs began as the manual wind 44GS in 1966 , and culminated in the automatic 61GS in 1968. The 61GS line was the result of refinements over the years including technology from the Astronomical Observatory Concours of the late 1960s.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe watch was designed by Taro Tanaka, the first graduate of a college design programme hired by Seiko. He wanted to design a watch that would “sparkle brilliantly” while on display, one that would compete with the Swiss watches of the time. He came up with a set of rules that would come to be known as the “Grammar of Design.” This meant perfectly flat surfaces and angles for cases, dials, hands and indices. All distortion would be eliminated, and the case finish would have a mix of high polish and brushed surfaces, couples with razor-sharp edges. The 6146-8000 is a perfect example of this design philosophy. Brilliant flat surfaces of mirror finish, with sharp lines delineating the different planes.\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cstrong\u003eOUR THOUGHTS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe Grand Seiko 6146-8000 is a true classic. Featuring the high-beat Cal 6145, it runs at 36,000 vibrations per hour for impressive accuracy. Its sharp, polished design reflects Seiko’s “Grammar of Design,” setting a new benchmark for Japanese watchmaking. Released in 1968, it showcased Seiko’s push to compete with Swiss brands. With its clean dial, quickset date, and lasting quality, it remains a highly sought-after vintage piece.\u003c\/p\u003e","brand":"Past2PresentWatches","offers":[{"title":"Default Title","offer_id":58374383468931,"sku":"GS9363WO","price":1395.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/2397\/4423\/files\/grand-seiko-6145-8000-front-_18.jpg?v=1783076785","url":"https:\/\/past2presentwatches.com\/products\/vintage-grand-seiko-6145-8000-watch-hi-beat-36000-automatic-1969","provider":"Past2PresentWatches","version":"1.0","type":"link"}
