The ultimate in metal form, created with leading-edge technology and time-honoured artisanship — unparalleled strength and beauty befitting the pinnacle of the G-SHOCK brand

Basara was a term of respect used for samurai commanders who shattered conventions with a rebellious style that combined strength and a bold, lavish aesthetic. For this trailblazing watch, we first specially commissioned the making of an actual, one-of-a-kind MR-G Hana-Basara suit of armour based on the Basara commander spirit. Then we created this exceptional watch using the armour as the design motif. Employing ultra-hard COBARION and DAT55G alloys developed in Japan and inviting in a cutting/polishing artisan to apply techniques rarely used in metalwork, we achieved mirror-surface facet cuts in metal — a feat considered virtually impossible. This watch exudes a distinctive aesthetic sensibility and worldview that embraces two of Japan’s proudest heritages: cutting-edge technology and traditional craftsmanship.




Born of artisanal technique and spirit, facet-cut bezel

For the bezel, we employed a facet-cutting technique borrowed from the gemstone arts. Cutting/polishing artisan KOMATSU Kazuhito applied crisp polishes to the many facets with their varying angles to achieve a brilliant, gleaming finish. Working with an ultra-hard alloy that is very tricky to process, kept production limited to just a few pieces per day — an intricate process that elevates this metal design to the realm of an artform.

KOMATSU Kazuhito

Cutting/polishing craftsman

President of the Komatsu Cutting Factory. Known foremost for his Hana Shinju faceted pearls produced by applying cuts to the surfaces of genuine pearls using traditional diamond-cutting techniques. The first Japanese artisan awarded 1st prize in the U.S.-based “Gemmy” awards for gem-cutting in 2009. Also awarded the 3rd Monodzukuri Nippon Grand Award Prime Minister’s Prize. One of the foremost Japanese artisans in this field, highly esteemed worldwide.

Super-hard alloys developed in Japan, combining strength with beauty

The bezel is made of COBARION®, a cobalt-chrome alloy boasting a hardness about four times that of pure titanium and said to have a more brilliant gleam than platinum. The case and band employ DAT55G, a titanium alloy with a hardness about three times that of pure titanium that offers excellent processability. With these super-hard alloys developed in Japan, we achieved an exterior design that delivers both strength with beauty.

Dark green DLC surface,
reproducing a time-honoured Japanese hue

The traditional Japanese hue kurogane-iro (literally “iron colour”) is reproduced on the bezel and band with our newly developed dark green DLC finish.
A name derived from the deep shade of green that appears on the surface of iron heated to high temperatures,
the colour evokes the distinguished presence of the iron-clad helmet and armour Basara samurai commanders wore.

Face design inspired by
Hana-Basara armour

The dial design incorporates a kusari katabira chainmail-inspired woven pattern and mirror-finished components with a folding fan pattern.
The index features a curved form achieved with nanoprocessing to evoke the curvature of
a Japanese sword. Adopting the Hana-Basara armour’s blend of green, red, gold and black hues, the watch face presents a creative design look.
