A lightweight titanium Perpetual Calendar from Seiko’s JDM “Big Date” Kinetic line. Very rare.

Model: SAGV005 / 7D48-0AD0 Seiko Kinetic Perpetual

Year: March 2008

Features:

The Design. One of the other frequently sought after “Grail Kinetics”. The grey dial of the SAGV005 initially appears chequered, but closer inspection reveals it’s simply a clever optical illusion created by its ridged texture. Housed in the much-loved titanium cushion case, the SAGV005 remains one of Seiko’s most wearable and collectible designs. The perfect mix of comfortable, stylish and distinct.

JDM. Only produced for a short time and only sold in Japan, this is a classic unintentional “limited edition” from Seiko. This watch rarely comes up for sale in the West.

Kinetic Movement. The 7D46 movement is 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 and then passed through quartz crystal.

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. When not in use, the watch enters “auto relay” mode which is essentially a form of hibernation. While hibernating, in order to conserve power, 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 all of 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.

High-End. It was a part of Seiko’s luxury line up at the time of release, costing over $1300 at the time, not adjusting for inflation. It features a sapphire crystal and a titanium cushion case with the original titanium bracelet.

Specifications:

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, new, or modified), and the import and tax 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?

All of our watch mods are tested by our own pressure depth testing equipment, and are guaranteed to resistant water up to 50m of depth. Seiko Originals have varied levels of depth resistance, which will be stated in the description of each watch.

Can I modify an existing design?
