Model: Seiko 7D46-0AE0 “Big Date” Kinetic Perpetual

Year: October 2008

Features:

The Hybrid. A 7D46 “Kinetic” movement. Kinetic movements originally served as a hybrid pre-cursor to the Grand Seiko’s Spring Drive movement. Just like in an automatic mechanical watch, your arm/wrist movements spin a rotor that powers the watch. However, unlike a standard automatic movement, energy is stored in a capacitor.

The Complication. The main complication is a leap year Perpetual Calendar with Big Date. The primary concern with an automatic perpetual calendar is the inconvenience of having to regularly reset it when it runs out of power. However, thanks to the “relay mode” you won’t have to worry about that as your watch will enter a hibernation state if you don’t wear it for a day. While hibernating the watch stops ticking, but a tiny IC stays powered and keeps track of the time and date. As soon as you pick the watch up the hands spring to life and the calendar and time set themselves accurately. It can stay in a state of hibernation for up to four years!

The Advantages. Being a hybrid between mechanical and quartz has several distinct advantages. Thanks to the quartz crystal the watch is accurate to +/- 15 seconds per month. However, unlike a quartz watch you don’t need to replace the battery every 1 or 2 years as the battery isn’t generating the power; your movement is. The recommended replacement for a Kinetic Capacitor is every 10-20 years! When fully powered, the watch has a huge 10-day power reserve.  

The Materials. The lightweight case and bracelet are made of solid titanium, ensuring exceptional comfort for everyday wear.

Condition: In very good condition overall. There are small scratches on the case and bezel. The photos represent the condition well. 

Scope: No original box or papers. 

Movement: 7D46 Kinetic Perpetual Calendar. 10-day power reserve, and a 4-year hibernation state if the watch is unworn.

Dimensions:

  • Case Width: 40.0mm
  • Case Thickness: 12.3mm
  • Bracelet Size: Fits up to 7.2 inch wrist

FAQs

Are your watches authentic?

Everything we sell is 100% authentic.

All of our watches are inspected and verified for authenticity - both inside and out. We have over 15 years of sourcing and collecting rare watches in Japan, which is often considered to be one of the best markets for authentic and fully original vintage watches.

Do you ship globally?

We are based in Japan and regularly ship all over the world. We typically use FedEx and it takes:

  • 3-7 business days to reach North America
  • 3-7 business days to reach Europe
  • 3-7 business days to reach Asia and Oceania.

All of our packages are securely shipped, fully insured, and trackable door-to-door.

Are all of your watches serviced?

Most but not all of our watches are serviced. The "Condition" section of each watch will confirm if the watch has been serviced.

All of our watches are tested by an independent watchmaker - if a service is needed, the watch will be serviced. If a service hasn't been conducted, it's because the watch itself is too new to need a service, or there is evidence of a recent service.

What payment methods do you accept?

We accept payment by all major Credit Cards and Wise.com

What condition are your watches?

Due to the vintage and neo-vintage nature of the watches we typically sell, the condition varies from watch to watch. However, our photos are high resolution and our descriptions are accurate. You can buy with confidence knowing there won't be any nasty surprises.

If the condition of a watch is ever misrepresented, we would offer a full refund.

Do I have to pay customs or taxes?

It depends on so many factors, including but not limited to the cost of the watch, the type of watch you've bought (vintage or new), and the import laws of your country. If you're unsure we recommend checking the import laws that relate to your country before ordering.

Are your watches water resistant?

Our serviced watches are typically tested to their original water resistant specifications, but we would never recommend pushing vintage or neo-vintage watches to their depth limits.

What is your returns policy?

Due to the vintage and neo-vintage nature of most of our watches, we do not offer returns under normal circumstances. All sales should be considered final.
