The Edo purple of Tokyo, on your wrist
Seiko 5 Sports SKX Edo Purple: a very special edition
The Seiko 5 Sports HDB003K1 brings the well-known SKX aesthetic to a limited edition that stands out above all for its Edo purple dial. With a 42.5 mm diameter and production limited to 9,999 pieces worldwide, it keeps the sporty personality of Seiko 5 Sports but with a much more distinctive finish.
Edo purple is inspired by Edo-murasaki, a shade of purple associated with clothing during the Edo period. Seiko uses it here as the main design element, combining it with gold details on the Seiko 5 Sports logo and the Automatic inscription. The result is a dial that changes considerably depending on how the light hits it, thanks to its sunray finish.
The case takes the shapes of the SKX series as its starting point, with the crown at 4 o'clock and a unidirectional rotating bezel. The three-row stainless steel bracelet completes the package and maintains that sporty character, while the transparent case back allows you to see the automatic movement.
It is also designed for everyday use. It has 10 bar water resistance, LumiBrite on the hands and indexes for easy reading in low light, and a screw-down case back with the LIMITED EDITION inscription. These are details that maintain the functional character of Seiko 5 Sports even in an edition where design carries special weight.
Inside works the well-known 4R36 caliber, an automatic movement with manual winding that offers day and date, hacking seconds and approximately 41 hours of power reserve. A simple, proven movement that fits the philosophy of Seiko 5 Sports.
This Seiko 5 Sports HDB003K1 comes with the official Seiko warranty and the backing of our status as an official Seiko dealer in Vigo.
Frequently asked questions
How much can it deviate per day?
The 4R36 caliber has a precision specified by Seiko of −35/+45 seconds per day. In an automatic movement, it is normal for the time to gain or lose; the rate can also vary depending on the position in which the watch is left, temperature or use.
If you are looking for maximum accuracy and do not want to correct the time occasionally, a quartz watch offers greater precision. In an automatic like this Seiko 5 Sports, these small variations are part of the normal operation of a mechanical movement.
Why is it a limited edition?
The Seiko 5 Sports HDB003K1 is produced in a limited run of 9,999 pieces worldwide, making it a collector's piece. It is designed to commemorate the 145th anniversary of Seiko's founding. Once production is sold out, it will not be made again. The case back bears the "LIMITED EDITION" inscription.
Can I get it wet?
The manufacturer declares a water resistance of 10 bar (100 m). This means the watch is suitable for swimming and recreational water use, provided it is not used for scuba diving and the crown is not operated underwater.
Is 42.5 mm large?
It is a sporty size, in line with the SKX series from which it inherits its design. The asymmetrical case, with the crown at 4 o'clock, and its 46 mm lug-to-lug distance make it feel substantial but comfortable on medium or large wrists. If you are coming from 38–40 mm watches, you will notice a considerable presence.
