SEIKO – Presage Urushi Byakudan-nuri Edition



















SEIKOPresage Urushi Byakudan-nuri Automatic Limited Edition


Urushi Byakudan-nuri lacquer and the moon at dawn.
An inspired combination.

A new creation in the Presage collection of fine mechanical watches takes its inspiration from Japan’s everlasting fascination with the moon. Following on from the success of the recent release of a deep blue enamel dial that evoked the night sky, this new limited edition uses one of the most elaborate lacquer techniques of all, Byakudan-nuri, as well as traditional Urushi, to portray the rich tones of the sky and moon just before dawn.

The crescent shaped tip of the second hand is coated with a gold powder, giving it a special texture that resembles the surface of the moon. The power reserve indicator evokes the brilliance of the crescent moon illuminated by the sun. The crescent shape is also to be seen on the sapphire crystal case back, affixed by vapor deposition.


The Byakudan-nuri

Byakudan-nuri is a technique that has been used for centuries to decorate Urushi lacquer and, because of the complexity of the craftsmanship involved, was reserved exclusively for use in places and on objects of high status, including temples, shrines and on the armor of Shogun warlords.

Lacquer ArtistIsshu Tamura

The complex processes, Urushi, Byakudan-nuri and Maki-e, are completed by hand by the craftsmen and women in the studio of Urushi master Isshu Tamura in the Hokuriku region of Honshu, Japan’s main island.

Born in 1957, Isshu Tamura trained in the traditional Kaga Maki-e gold lacquer technique of Kanazawa. After honing his skills in the technique, Mr. Tamura set out to produce unparalleled original works of art. He has executed his technique in Kaga Maki-e not only in lacquerware, but also in the creation of luxury fountain pens and wristwatches which have received worldwide acclaim for their elaborate detail and fine beauty.

Urushi

First, the dials are made with the traditional Urushi technique in which jet black lacquer is painted by hand onto the metal base of the dial, dried and then polished.

These processes are repeated several times until the craftsman has achieved the exact depth of black that he desires.

Byakudan-nuri

Using a new layer of Urushi as the binding agent, the sub-dials are then sprinkled with a layer of very fine metallic powder. The whole dial is then repeatedly painted with a red-tinged semi-transparent Urushi lacquer and then each new layer is dried and polished for as many times as the craftsman deems necessary.

The effect is subtle but deeply satisfying. While the red of the sub-dials is deep, these two dials catch the light and shine when the ambient light grows brighter, just as parts of the sky catch the dawn light before others.

Maki-e

Now it is time to add the moon, using the Maki-e technique, in the form of the crescent shaped power reserve indicator. As with the Byakudan-nuri technique, the crescent is first coated with a layer of Urushi lacquer that acts as the adhesive for the fine, gilt-colored powder that is then applied to it.

Once the powder is on the dial, the craftsman gently taps it to disperse the powder evenly across the surface and then uses his own specially chosen material to perfect the surface.

The result is an indicator that not only reflects the shape of the crescent moon but has the moon’s shimmering, granular texture and contrasts with the smoothness of the sky against which it stands out.

CORUM – Bridges GOLDEN BRIDGE & Miss GOLDEN BRIDGE Diamonds























CORUMBridges GOLDEN BRIDGE & GOLDEN BRIDGE MISS “Snow” Exclusively Diamonds




For Christmas, Corum Covers 
Its Golden Bridges In Snow


The brand launches four editions of its famous Golden Bridge, decorated entirely with snow-set diamonds.

Christmas is in the air: just in time for the festive season, Corum is releasing two new versions of its Golden Bridge with a new “snow” setting. Made exclusively of diamonds, the snow setting involves arranging a random number of diamonds of all sizes in such a way that together, they cover up the entirety of the metal. It is a high-level jewellery practice for two reasons.

Firstly, the meticulous choice of the placement of each diamond. Though each one is different, they must still be as close to one another as possible, interlocking to the micron so the edges are almost touching. There is thus no consistency in this task, one which breaks away from the mechanics of brilliant and baguette cuts where all the diamonds are interchangeable.

In a snow setting, it is the setter’s own experience and daring which are at play. Each diamond is individually chosen and placed. The final composition is similar to a fresco or an expressionist painting, featuring many diamonds set individually and creating, together, the coherent image of a whole.

Next, there is the setting itself. As each diamond has a unique size, so too must each claw used for setting. It is a task requiring extreme precision which prevents the setting from being standardised, as each claw is individually worked to set its diamond and it alone.

“Ultimately, each snow-set Golden Bridge is completely unique”, explains Jérôme Biard, CEO of Corum. “They are at once true Fine Watchmaking and Fine Jewellery pieces, and we will never make two which are identical. This covering reflects Corums philosophy of thinking outside the box, of breaking with convention, to offer our collectors a calibre that is completely unique, our baguette movement, and a highly exclusive setting that had almost never been used in Corums history”.

Two models will be available in the snow setting: the Golden Bridge (with a 34 x 51 mm barrel- shaped case) and the Miss Golden Bridge (21 x 43 mm). Each case is fully set, including the crown, giving a unique glimmer to the baguette movement which stretches up and down the case and is entirely visible through the anti-reflective double sapphire crystal.

Each piece will be released in white gold and pink gold, meaning there are four models in total, for a total of 314 diamonds for the Golden Bridge and 245 diamonds for the Miss Golden Bridge, representing 2.68 ct and 1.28 ct respectively.
