2021 Grand Seiko GMT Quartz Blue 39mm SBGN005G

Here is a 2021 Grand Seiko GMT Quartz Blue SBGN005G from their Sports Collection. It has an impressively sculpted 39mm stainless steel case with exquisitely polished and brushed surfaces that curve over your wrist toward the drilled lugs. A lug-to-lug of 44.5mm and a case thickness of 11.5mm give the watch an impressive wrist presence. On the right side at 3 o’clock is a signed screw-down crown protected by crown guards, and a 24-hour satin-brushed steel fixed bezel with deeply engraved numerals filled in black holds a dual-domed sapphire crystal, AR-coated on the inside, above a dark sunburst blue dial. Applied Zaratsu polished facet-edged batons and trapezoid indexes mark the hours that play with the light as you rotate your wrist at 3 o’clock, a framed date window, an outer 24-hour chapter ring in blue for the night hours and silver for the daytime hours. Elegant dauphine hands are Zaratsu polished with razor edges filled with LumiBrite, a bright red arrow hand indicates the 24-hour position, and at 12 o’clock, we have the Grand Seiko motif and at 6 o’clock, a red “GMT”. On the reverse is a screw-down case back with the serial number engraved into it and a deeply embossed medallion in the centre, inside a Quartz Grand Seiko Cal. 9F86, this is a top-tier quartz movement. Seiko grows its own quartz crystals, and using a higher torque allows it to use these heavier GS hands, keeping its brand aesthetic intact. The watch comes fitted with its 19mm stainless steel bracelet, expertly brushed and polished, and features a push-button-release signed clasp, including all spare links. It also includes the Grand Seiko presentation box, swing tag, and paperwork.

This watch is sold with its original Grand Seiko Box, swing tag & unsigned Paperwork. The watch comes paired with its original stainless steel Grand Seiko signed bracelet with its Grand Seiko signed clasp, all spare links included. The watch is from October 2021 and is sold in worn condition, but overall very fair condition, as you can see from the photographs. The watch comes with our 12-Months Warranty.

Dials are what Grand Seiko do well and truly go above and beyond any brand in their price bracket. Anyone who has handled a Grand Seiko and louped a dial will know exactly what I am talking about. If you haven't, now is the time to book an appointment and see this incredible watch and our other Grand Seikos in the metal and see for yourself!

The first Grand Seiko debuted in Tokyo in 1960. The ref:3180 was made by Suwa Seikosha. In 1962, Taro Tanaka developed a set of design guidelines known as the "Grammar of Design," which aimed to create a cohesive look for Seiko watches. These guidelines encompassed nine key principles that distinguished the watches. Some of these principles involve Zaratsu polishing that makes the watch surfaces shine beautifully and reflect light in interesting ways. There’s also an emphasis on using unique shapes for the watch cases, ensuring that every part is perfectly shaped, and adding features like sharp, clean edges and well-designed hands and markers that catch the eye. Today, Tanaka's principles still apply to the modern Grand Seiko philosophy. Rather than sending its 25 Jewels Chronometer movement to the Swiss to be tested, Seiko decided to do the testing themselves. The European Chronometer Official Association believed that a chronometer-rated watch had to be independently tested to be awarded that designation. Seiko watches were not independently tested, so therefore they could not be chronometers. The ECOA did what irritated watchmakers do: they wrote a stern letter to Seiko requesting that the designation of Chronometer on Grand and King Seiko watches stop. Seiko obliged and ceased using a chronometer on their watches. In response, the Japanese Chronometer Authorisation Association was started in 1968 as an independent group to test timepieces to chronometer standards. The Association was short-lived: due to the rise of quartz watches, it closed in 1983. Today, Grand Seiko movements are tested over 17 days in 6 positions compared to COSC testing over 15 days in 5 positions. In 1985, Suwa Seikosha became Seiko Epson Corporation. In 2017, Seiko announced that Grand Seiko would become an independent brand.
