STONEBRIDGE WATCHES SAYS...
The Seiko Grand Quartz represents one of the finest achievements of Japan's golden era of watchmaking. Produced during a period of intense competition to create the world's most accurate quartz timepieces, the Grand Quartz line was positioned just below Grand Seiko and combined exceptional precision with the outstanding build quality for which Seiko became renowned. This particular example, reference 4843-8040, dates to circa 1975 and is a superb example of the understated elegance that has made these vintage high-accuracy quartz models increasingly sought after by collectors.
Its beautifully finished silver sunburst dial displays a subtle depth that changes with the light, complemented by polished applied baton hour markers and faceted hands that provide excellent legibility. The framed day and date display at three o'clock completes the balanced design, while the sharp stainless steel case retains the clean angular lines that are characteristic of Seiko's mid-1970s styling. The watch is fitted to its original Seiko Grand Quartz stainless steel bracelet, an increasingly desirable feature that adds both authenticity and collectability.
Powering the watch is the highly respected Seiko Calibre 4843, a High Accuracy Quartz movement developed during Seiko's pursuit of absolute precision. Engineered to standards far beyond ordinary quartz watches of the period, the 4843 movement is renowned for its reliability, quality of construction and excellent long-term performance, making it one of the standout quartz calibres produced during this era.
Measuring 36mm excluding the crown, the case offers a timeless size that wears comfortably on a wide variety of wrists. Its balanced proportions, slim profile and integrated bracelet give the watch a larger presence than its dimensions might suggest, making it equally suitable as an everyday watch or as part of a carefully curated vintage collection.
This Seiko Grand Quartz is presented in excellent vintage condition with a clean dial, crisp caseback engravings and its original signed bracelet. It is supplied with a Seiko presentation box and has been carefully inspected prior to sale.
At Stonebridge Watches, we specialise in vintage and smaller wristwatches chosen for their quality, originality and timeless appeal. Every watch is carefully selected to offer collectors an honest and enjoyable ownership experience, and this Grand Quartz is a wonderful example of Seiko's engineering excellence during one of the most significant periods in horological history.
