The 4832 movement uses a 32768 Hz quartz oscillator and incorporates 7 jewels in its construction to reduce friction in key parts. A distinctive feature of many watches with this movement is a “jumping seconds” behaviour when the crown is pulled out for setting, where the seconds hand advances to the nearest 10-second mark to aid precise synchronization. The 36 mm stainless steel case says true to Seiko's 'Grammar of design' and the dial brushed dial ads a touch of class, the design reflects Seiko’s 1970s aesthetic for its higher-end quartz watches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA BIT OF TRIVIA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe 4823 belongs to what collectors sometimes call Seiko’s “serious quartz” era. By the mid-1970s, quartz was no longer experimental, but it hadn’t yet become disposable. Movements like the 4823 were built with proper metal gear trains and robust construction, reflecting a time when quartz technology was still treated as premium engineering rather than mass-market convenience.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eBattery longevity was also a genuine selling point at the time. Multi-year running without intervention felt futuristic, especially compared to mechanical watches that required regular winding or servicing. The 4823 helped normalise the idea that precision timekeeping could be effortless and consistent.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eInterestingly, many watches housing the 4823 still retained strong mechanical-era design language. Applied indices, brushed sunburst dials, and sharply faceted 1970s cases give them the aesthetic of traditional watchmaking, even though the technology inside was thoroughly modern. That blend of old-world styling with contemporary quartz performance gives these pieces a subtle crossover appeal today.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eFrom a watchmaker’s perspective, another point of interest is that these movements were still designed to be serviced rather than discarded.

It is fitted with Seiko’s Calibre 9940 Twin Quartz movement, which uses two quartz crystals and a temperature compensation circuit to significantly improve timekeeping precision compared with earlier single-crystal quartz movements. This Twin Quartz system allowed the 9940 movement to achieve exceptional accuracy, far surpassing standard quartz accuracy measured per month.\u003c\/p\u003e\n\u003cp\u003eToday the Grand Quartz 9940-8000 is appreciated by collectors of vintage quartz watches and Seiko enthusiasts not just for its historical significance as part of Seiko’s high-accuracy quartz development, but also for its combination of accuracy, build quality, and period-typical styling that reflects Seiko’s technical leadership in the era when quartz fundamentally reshaped the watch industry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTWIN QUARTZ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTwin Quartz is Seiko’s temperature-compensated quartz system, introduced in the late 1970s. Unlike standard quartz watches that use a single quartz crystal, Twin Quartz uses two crystals along with a specialized circuit that compares their oscillations and corrects for temperature-related timing errors. This was important because temperature changes are the main reason quartz watches drift over time, and Twin Quartz was designed to eliminate that issue.\u003c\/p\u003e\n\u003cp\u003eThe way Twin Quartz works is fairly clever: the two crystals are cut so that their frequency shifts in opposite directions when temperature changes. As the temperature rises, one crystal’s frequency increases while the other decreases. The circuit compares the two frequencies and adjusts the output, effectively canceling out the temperature drift. This made Twin Quartz far more accurate than typical quartz watches of the era.\u003c\/p\u003e\n\u003cp\u003eTwin Quartz first appeared around 1978, and it was used mainly in Seiko’s high-accuracy Grand Quartz models.

Unlike standard quartz watches that use a single quartz crystal, Twin Quartz uses two crystals along with a specialized circuit that compares their oscillations and corrects for temperature-related timing errors. This was important because temperature changes are the main reason quartz watches drift over time, and Twin Quartz was designed to eliminate that issue.\u003c\/p\u003e\n\u003cp\u003eThe way Twin Quartz works is fairly clever: the two crystals are cut so that their frequency shifts in opposite directions when temperature changes. As the temperature rises, one crystal’s frequency increases while the other decreases. The circuit compares the two frequencies and adjusts the output, effectively canceling out the temperature drift. This made Twin Quartz far more accurate than typical quartz watches of the era.\u003c\/p\u003e\n\u003cp\u003eTwin Quartz first appeared around 1978, and it was used mainly in Seiko’s high-accuracy Grand Quartz models.

After Grand Seiko had largely disappeared during the Quartz Crisis of the 1970s, Seiko relaunched the brand in 1988 with a renewed focus on precision and refinement. The 8N65 series belongs to this first generation of modern Grand Seiko quartz watches and predates the introduction of the famous 9F movement family in 1993.\u003c\/p\u003e\n\u003cp\u003eThe watch is powered by the Calibre 8N65, a high-accuracy quartz movement rated to incredible accuracy. At the time, this level of precision placed it far above ordinary quartz watches and reflected Seiko’s ambition to produce luxury-grade quartz timepieces. Although not as technically advanced as the later 9F calibres, the 8N65 represented an important step in the development of Grand Seiko’s modern quartz technology and established many of the principles that would later define the brand.\u003c\/p\u003e\n\u003cp\u003eThe 8N65-8000 was designed as a refined dress watch with compact proportions and understated styling. Featuring a slim stainless steel case around 35mm in diameter, sapphire crystal, applied hour markers, dauphine-style hands, and sharply polished surfaces associated with Grand Seiko finishing traditions. Its clean and restrained design reflects the Japanese approach to luxury and precision that became central to Grand Seiko’s identity.\u003c\/p\u003e\n\u003cp\u003eToday, collectors value the 8N65-8000 as an important “pre-9F” Grand Seiko and a significant part of the brand’s early modern history. Enthusiasts appreciate the watch for its elegant proportions, impressive quartz accuracy, and historical importance within the evolution of Grand Seiko. Well-preserved examples with original dials and sharp cases have become increasingly sought after, especially among collectors interested in early high-accuracy quartz watches.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA BIT OF TRIVA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Grand Seiko Calibre 8N65 is interesting because it represents one of Seiko’s earliest modern high-accuracy quartz (HAQ) movements produced after the relaunch of Grand Seiko in 1988. It was designed during a period when Seiko was trying to prove that quartz technology could still be luxurious, precise, and technically sophisticated rather than simply inexpensive and disposable.\u003c\/p\u003e\n\u003cp\u003eUnlike many cheap quartz movements of the period, the 8N65 was built to a luxury standard. The movement was carefully regulated at the factory and designed for longevity rather than simple replacement. Some examples still maintain extremely high accuracy decades later, which has helped build the calibre’s reputation among collectors.\u003c\/p\u003e\n\u003cp\u003eBecause the movement was produced before Grand Seiko became globally popular, relatively few people outside Japan were aware of watches like the 8N65-8000 for many years. As a result, collectors today often describe the calibre as an overlooked or “hidden gem” within Grand Seiko history.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ch4\u003e\u003cstrong\u003eOUR THOUGHTS\u003c\/strong\u003e\u003c\/h4\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp\u003eThe Grand Seiko 8N65-8000 feels like a forgotten chapter in Grand Seiko history, understated, precise, and quietly impressive. Its slim case and restrained design capture a kind of luxury that modern watches rarely aim for anymore. The 8N65 movement may predate the famous 9F, but it already showed Seiko’s obsession with accuracy and refinement. To me, it represents the moment Grand Seiko proved quartz could still be serious horology.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Past2PresentWatches","offers":[{"title":"Default Title","offer_id":58140103278979,"sku":"GSQ2600WO","price":795.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0783\/2397\/4423\/files\/grand-seiko-quartz-8N65-8000-front-_3.jpg?v=1780056124"},{"product_id":"vintage-seiko-king-quartz-4823-8000-watch-1976","title":"Vintage Seiko King Quartz 4823-8000 watch 1976","description":"\u003cp\u003e\u003cstrong\u003eSPECIFICATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReference\u003c\/strong\u003e: King Quartz\u003cbr\u003e\u003cstrong\u003eMovement\u003c\/strong\u003e: Quartz 4823\u003cbr\u003e\u003cstrong\u003eAge\u003c\/strong\u003e: April 1976\u003cbr\u003e\u003cstrong\u003eCase Size\u003c\/strong\u003e: 36mm\u003cbr\u003e\u003cstrong\u003eCase Thickness\u003c\/strong\u003e: 11mm\u003cbr\u003e\u003cstrong\u003eLug to Lug\u003c\/strong\u003e: 41mm\u003cbr\u003e\u003cstrong\u003eLugs\u003c\/strong\u003e: 19mm\u003cbr\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e: Used Seiko watch\u003cbr\u003e\u003cstrong\u003eBox \u0026amp; Papers\u003c\/strong\u003e: No\u003cbr\u003e\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003cbr\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e: 12-Months Warranty\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003ePOINTS TO MENTION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIn fantastic pre-owned condition, with light wear from use\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCase and bezel have some very light scratches and mark\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVertically textured dial\u003cspan\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eServiced Movement\u003c\/li\u003e\n\u003cli\u003eNew battery fitted\u003c\/li\u003e\n\u003cli\u003eEnglish and Kanji day wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eQuartz signed crown\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePaired with an unworn grey epsom leather strap\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTHE WATCH\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Seiko King Quartz 4823-8000 is a vintage quartz wristwatch from Seiko’s premium King Quartz lineup of the 1970s, powered by the Caliber 4822 high-grade quartz movement.

The 4832 movement uses a 32768 Hz quartz oscillator and incorporates 7 jewels in its construction to reduce friction in key parts. A distinctive feature of many watches with this movement is a “jumping seconds” behaviour when the crown is pulled out for setting, where the seconds hand advances to the nearest 10-second mark to aid precise synchronization.

Unlike standard quartz watches that use a single quartz crystal, Twin Quartz uses two crystals along with a specialized circuit that compares their oscillations and corrects for temperature-related timing errors. This was important because temperature changes are the main reason quartz watches drift over time, and Twin Quartz was designed to eliminate that issue.\u003c\/p\u003e\n\u003cp\u003eThe way Twin Quartz works is fairly clever: the two crystals are cut so that their frequency shifts in opposite directions when temperature changes. As the temperature rises, one crystal’s frequency increases while the other decreases. The circuit compares the two frequencies and adjusts the output, effectively canceling out the temperature drift. This made Twin Quartz far more accurate than typical quartz watches of the era.\u003c\/p\u003e\n\u003cp\u003eTwin Quartz first appeared around 1978, and it was used mainly in Seiko’s high-accuracy Grand Quartz models.

Unlike standard quartz watches that use a single quartz crystal, Twin Quartz uses two crystals along with a specialized circuit that compares their oscillations and corrects for temperature-related timing errors. This was important because temperature changes are the main reason quartz watches drift over time, and Twin Quartz was designed to eliminate that issue.\u003c\/p\u003e\n\u003cp\u003eThe way Twin Quartz works is fairly clever: the two crystals are cut so that their frequency shifts in opposite directions when temperature changes. As the temperature rises, one crystal’s frequency increases while the other decreases. The circuit compares the two frequencies and adjusts the output, effectively canceling out the temperature drift. This made Twin Quartz far more accurate than typical quartz watches of the era.\u003c\/p\u003e\n\u003cp\u003eTwin Quartz first appeared around 1978, and it was used mainly in Seiko’s high-accuracy Grand Quartz models.

It is fitted with Seiko’s Calibre 9940 Twin Quartz movement, which uses two quartz crystals and a temperature compensation circuit to significantly improve timekeeping precision compared with earlier single-crystal quartz movements. This Twin Quartz system allowed the 9940 movement to achieve exceptional accuracy, far surpassing standard quartz accuracy measured per month.\u003c\/p\u003e\n\u003cp\u003eToday the Grand Quartz 9940-8000 is appreciated by collectors of vintage quartz watches and Seiko enthusiasts not just for its historical significance as part of Seiko’s high-accuracy quartz development, but also for its combination of accuracy, build quality, and period-typical styling that reflects Seiko’s technical leadership in the era when quartz fundamentally reshaped the watch industry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTWIN QUARTZ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTwin Quartz is Seiko’s temperature-compensated quartz system, introduced in the late 1970s. Unlike standard quartz watches that use a single quartz crystal, Twin Quartz uses two crystals along with a specialized circuit that compares their oscillations and corrects for temperature-related timing errors. This was important because temperature changes are the main reason quartz watches drift over time, and Twin Quartz was designed to eliminate that issue.\u003c\/p\u003e\n\u003cp\u003eThe way Twin Quartz works is fairly clever: the two crystals are cut so that their frequency shifts in opposite directions when temperature changes. As the temperature rises, one crystal’s frequency increases while the other decreases. The circuit compares the two frequencies and adjusts the output, effectively canceling out the temperature drift. This made Twin Quartz far more accurate than typical quartz watches of the era.\u003c\/p\u003e\n\u003cp\u003eTwin Quartz first appeared around 1978, and it was used mainly in Seiko’s high-accuracy Grand Quartz models. The most famous Twin Quartz movement is the Caliber 9940, which powered watches like this Grand Quartz 9940 and similar references.
