Introducing the Seiko " 5 Actus" made in 1970 .

The 5 Actus is a model series launched in 1970 targeted at young people.

Despite being reasonably priced, they come in a wide variety of designs and feature various functions such as automatic winding, water resistance, and day-date functions.

The 5 Actus was a popular watch among young people because it was a watch that was aimed at new workers and young people at the time, with young people featured in advertisements to reflect changes in people's lifestyles.


The Seiko " 5 Actus" we are introducing this time is a smart watch with a black dial.

The index is an upright bar index with a matte center and multi-faceted cutting process, which requires a lot of effort and cost.

The hands are dolphin hands with luminous paint in the center, and have a simple design that emphasizes practicality.
In addition, the black dial reduces light reflection, making it easy to see.

The dial is made of glass, which enhances its sharpness.

Looking at the case, we see that the crown at the 4 o'clock position is stored inside the case.
Not only does it provide a comfortable fit, but it also features a clean, smooth case silhouette.

The 5 Actus has a powerful and refined look, with all unnecessary decoration stripped away to highlight the appeal of the black dial.

The movement is a 23 jewel automatic, Cal. 6106C .

It is designed with practicality in mind, so it has stable operation and high durability.

It is equipped with a hack function that stops the second hand, and the calendar allows both the date and day of the week to be operated using only the crown.

This is a movement that even those who are new to vintage watches can use with confidence.


Size: height: 38.5mm , width: 35.9mm , thickness: 9.2mm , weight: 83g .

It's the perfect size for an average man's wrist.
The simple design makes it suitable for casual wear such as shirts, polo shirts, and T -shirts, as well as suits and jackets for business occasions.


The condition of the case is good with only minor scratches from use and no noticeable dents.
The dial is in beautiful condition with no fading or discoloration.
The movement is working fine and all functions such as the calendar work without any problems.


It is equipped with a genuine Seiko 5 Actus metal bracelet.

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

When selling antique watches at RESUME, we do not immediately hand over the watch to you upon receiving your order. Instead, we ask a professional craftsman to overhaul it (hereinafter referred to as OH) and deliver it 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 we 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 properly repair the product, but there will be a fee. If there is no repair shop near you, please feel free to contact us.
