Raden is a traditional decorative technique in which the nacreous layers of shells such as green turban
shell and
mother-of-pearl are carefully cut and applied to the surfaces of lacquerware and woodcrafts. Its defining
characteristic
is the way its colors shift depending on the angle of light. The character “ra” (螺) refers to spiral shells,
while “den”
(鈿) signifies inlay.
Its history dates back to ancient Mesopotamia. Introduced to Japan during the Nara
period, raden has captivated
generations across more than 1,300 years of history and continues to be celebrated today as one of Japan’s
defining
traditional crafts.

Aizu Traditional Artisans
The title of “Traditional Artisan” is only awarded to technicians working in the manufacture of traditional
crafts who
possess advanced artisanal skills and techniques.
The dial has been realized in collaboration with Nobuichi
Otake, a Traditional Artisan whose work employs sophisticated
technical skills and an original sense of style.
Nobuichi Otake,
Traditional Artisan
Born in 1959, Kaneyama, Fukushima Prefecture.
Upon completing high school, Nobuichi Otake initially
worked at a hydroelectric power station. However, he had aspired
to work as a painter ever since he was a child. He happened to learn about the maki-e lacquer art
profession while
watching TV, and became an apprentice to Sone Takuo, a contemporary master artisan of Aizu lacquerware.
After five years
and five months as an apprentice, he became an independent Aizu lacquerware maki-e craftsman.
The Raden Production Process
1. Base coating
After filtering to remove any impurities, lacquer is applied to the dial so that the shell pieces can
adhere to it.
This must be done evenly and with the right thickness, since this will determine the
final result.
2. Shell crushing
The shells are crushed into small pieces before being distributed over the
dial, all entirely by hand.
The shiny inner layer of the finely processed shell is carefully crushed
into small and medium-sized pieces.
3. Distribution of shell pieces
Shell pieces of different colors and shapes are applied in a balanced manner according to the craftsman’s
intuition.
The color and shape of the shell pieces are adjusted to create a gentle gradient from the
center, before finishing with
fine flakes applied through a powder tube.
4. Coating application
The lacquer is applied again to cover the distributed shell pieces.
This fills the spaces between the
shell fragments, allowing the lacquer and shell to shine together as a uniform
surface.
5. Polishing
After the layers of lacquer have thoroughly dried, the surface is polished so that the shell pieces can reveal their full brilliance. Through this process, the lacquer and shell pieces become smooth and shine as one. Too much polishing can cause the shell pieces to chip, so this is a highly delicate process carried out with a craftsman’s touch.
The Craftsmanship
Behind Blue Glacier
& Sumi Monochrome
Gradient Finish
To ensure legibility of the hour markers, the raden is arranged in a gradient pattern that evolves toward the
outer edge
of the dial. The exacting vision of Knot’s product designers is brought to life by hand by the traditional
artisan.
The natural shell pieces are arranged at consistent intervals, adjusting the color and size as the
gradient transitions
towards the edge. This intricate effect is a result which can only be achieved by the skilled hand and
intuition of a
master.
Styling
An Exclusive Package, Made for Raden
The watch is presented in a Premium Automatic Collection box accompanied by an exclusive sleeve designed
specifically

The sign of ahigh-performance timepiece: high-beat movement
For the movement – the watch’s beating heart – Knot has adopted the movement made in Japan.
This
high-beat movement oscillates 28,800 times per hour (8 times a second), reducing the distance of the swing
of the
second hand and drastically increasing the precision of the watch.
“Sallaz Polishing” is synonymous with luxury Japanese-made mechanical watches A clear mirror-finished case, polished to perfection by the hands of skilled craftsmen
The Knot Premium Automatic model uses a case made from 316L surgical stainless steel – an exceptionally high-purity alloy also used in medical settings – and finished with Zaratsu polishing. Zaratsu mirror polishing is an advanced finishing technique that creates flat, distortion-free surfaces with sharply defined edges. Only a very small number of craftsmen are capable of performing this process, earning it the reputation of “phantom polishing”. Today, it is rarely seen outside high-end Japanese-made watches. By polishing each surface individually, different expressions can be drawn out from the same material. This highly sophisticated technique is made possible by the veteran craftsmen at Hayashi Seiki Seizo.
Staineless Steel Case
SUS316L
The case is made from high-purity stainless steel SUS316L, a corrosion-resistant material also used in
surgical
instruments. This metal emits almost no ions that can cause allergic reactions, making it safe to wear even
for those
with metal sensitivities.*
*Please note that this does not guarantee that all individuals will be
free from allergic reactions.
Non-reflective,
coated sapphire glass
The crystal of the Premium Automatic series utilizes the same level of sapphire glass with anti-reflective coating that can be found in luxury watches. The coating is on one side only, which increases the visibility of the clock face while at the same time minimizing discoloration of the glass.
3-Year Warranty
The Premium Automatic Series comes with a 3-year warranty from the date of purchase, designed to be cherished for years to come. Knot also operates its own atelier, offering repair and maintenance services to ensure your watch stays in excellent condition. For more information, please visit our Repair Inquiries page.
