Exhibiting at Watches & Wonders in Geneva for the first time, Seiko’s high-end marque Credor is rolling out the Credor Goldfeather Tourbillon Engraved (ref. GBCF997).

While the latest Credor is only a cosmetic variation of an existing model, but the latest Goldfeather Tourbillon is nonetheless a top-of-the-line model in both technical and decorative terms: the ultra-slim movement features a tourbillon, while the dial and movement are hand engraved.

The hand-engraved cal. 6850

Initial thoughts

Though this year’s Goldfeather Tourbillon is identical to last year’s edition save for decor, it looks strikingly different, underlining the different decorative techniques employed. While last year’s model was ornate and figurative, the latest version is clean and almost monochromatic.

The lack of colour belies the complexity of the dial decoration. The entire dial is engraved, right down to the radial graining. Instead of conventional brushing, the radial pattern is achieved with a manual engraving technique.

The stylistic different continues onto the movement, which is equally finely decorated, and also impressively slim. While the strength of the artisanal execution and ultra-thin watchmaking are obvious, the Goldfeather Tourbillon is fundamentally a facelift to a movement that’s been around for a long time. To go as far as its sister brand Grand Seiko, Credor would have to do something more novel.

Fine lines

The Goldfeather Tourbillon Engraved is self descriptive: it is all about engraving. The engraving on the dial and movement is almost entirely comprised of lines of varying widths and dots of different diameters, yet the result is nuanced and vivid.

The two piece dial is finished with a fine linear engraving in a radial pattern, giving it the appearance of a conventional brushed dial, at least at a distance. The Roman numerals are similarly hand engraved, as are the dots for the minute scale.

The bridges of the ultra-thin cal. 6850 are finished with similar techniques. A range of lines and dots cover the bridges in a radial arrangement, creating a sense of motion originating from the tourbillon.

As with Credor’s other extra-thin watches, engraving the bridges is especially challenging due to the slimness of the parts, which are as thin as 0.25 mm. The bridges are set in a specially designed vice and then engraved to ensure flatness is preserved; even the slightest distortion of the bridge will result in a misaligned pivot.

Aesthetics aside, this Goldfeather Tourbillon is identical to last year’s model, being the same slim platinum specimen that’s just 8.6 mm high.
