SEIKO 70's 61 GRAND SEIKO SPECIAL / Cal.6156A

Introducing the Seiko " 61 GRAND SEIKO SPECIAL " made in 1970 .

The 61 Grand Seiko was released in 1968 by Suwa Seikosha as the second generation Grand Seiko automatic model.

What is noteworthy is that the movement it is equipped with, Cal. 6145 , is the first 10- beat automatic high-beat model in the history of Japanese-made watches.

As this was the first domestically produced high-beat model, the various requirements for a watch, such as precision and durability, were extremely high, and development proceeded using all of the technology and experience that Seiko had at the time.

As a result, it has better isochronism than previous movements and achieves more stable, high accuracy even when subjected to posture differences and external disturbances.
It has passed Seiko's own " GS inspection standard," which is said to be stricter than chronometer standards.
It is one of the great watches that had a major impact on the development of later Seiko movements.

The " GS Standard" is Seiko's own testing standard.
The GS standards are said to be stricter than the chronometer standards of the time, and the " 61 Grand Seiko" (hereinafter referred to as " 61GS "), which meets the GS standards, boasts extremely superior precision.

The 61GS Special has precision standards that are stricter than the GS standard and has a movement that has been specially adjusted to meet these challenges.

It boasted top-class precision even among domestic models at the time, and due to its specially adjusted characteristics, it is a highly rare piece with only a limited number available.

The dial has aged to a pale beige, giving it an appealing vintage look.
The letters " GS " and " SPECIAL " are engraved at the 6 o'clock position, and both are colored gold, emphasizing the exclusivity of the " 61GS Special."

The stainless steel case adopts the Seiko style, which emphasizes the surfaces and edges and gives off a sharp luster.
Compared to the standard 61GS , the case diameter is one size smaller, giving the design a sharper look.

At the time, Seiko poured their efforts into developing the 61GS Special as the pinnacle of Grand Seiko in terms of both precision and design.
This is a watch that allows you to enjoy the essence of Japanese manufacturing.

The movement is equipped with the automatic winding model Cal. 6156A .

The movement has been adjusted specifically for this model, ensuring extremely high precision.
In addition, the high beat specification provides high isochronism, so accuracy will not be compromised even in a variety of usage environments.
It is packed with high levels of precision, ease of maintenance, and practicality.

Other features include a hack function that stops the second hand and a day-date function.
The days of the week are written in both English and Japanese.
Both the date and day of the week can be fast-forwarded by operating the crown, making it highly practical.

Size: height: 40.9mm , width: 37.7mm , thickness: 12.3mm , weight: 51g .

It has a simple design that is highly practical, but the sharp luster of the Seiko style gives it a strong presence when worn.

Of course, it goes well with suits and jackets, but it is also stylish, so it can be interesting to pair it with casual styles such as shirts and denim jackets.

Condition: The case has some small scratches, but no noticeable chips.
The medallion on the back cover has some light damage on the edges, but does not affect use.
The dial has changed color due to aging, but this does not affect visibility.
The movement is working fine and the calendar function works fine.

All watches sold in our store are internally inspected by a professional watch mechanic upon arrival and are only sold after being determined to be genuine, so you can use them with confidence.

When you purchase a watch, we will attach a new leather strap to it when you deliver it to you.
Please select the color you want from the order selection tab and place your order.
*For products that come with original watch straps or metal bands, the leather strap will not be attached and will be sent separately as a spare.
A special case for the watch will also be included with the shipment.

Please be sure to read the following information after purchasing an antique watch.

When selling antique watches at RESUME, we do not immediately hand them over to you when you place your order. Instead, we ask a professional craftsman to overhaul them (hereafter referred to as OH) and deliver them to you after the OH is completed. (This takes about 1 to 2 months.)

A professional craftsman with first-class watch repair technician qualifications will completely disassemble your watch, replace worn parts such as the internal gaskets, clean it, oil it, and perform a thorough overhaul, maintaining it to a daily accuracy of about ±1 minute.
When we deliver the machine, we will also send you our own overhaul certificate, which shows what kind of overhaul was performed, as well as photos of the machine being disassembled and maintained.

Of course, due to the nature of the product itself being a second-hand item, there is no guarantee that it will never break, but we ask for your understanding that we take this approach so that you can enjoy the original performance of the watch and use it with peace of mind in the future.

When you purchase a product, we offer a one-year warranty depending on the model. Even if the warranty period has expired, we will still repair the product for a fee. If there is no repair shop near you, please feel free to contact us.
