2010s Credor Signo Skeleton Platinum
A Signo with a mesmerizing skeleton dial, an ultra thin platinum case, and the Seiko 6899A hand-wound movement.
Overview
Credor has been around since 1974 with a focus on precious metal cases and fine art techniques. While it's a subsidiary of Seiko, the level of handiwork and extravagance is closer to independent watchmaking than what's seen in the more mainstream Japanese brands. Many are familiar with the Eichi models, but few realize the brand's breadth goes far beyond hand-painted porcelain dials.
The GBBD985 here is from Credor's appropriately named Art Piece Collection, and is an evolution of the skeletonized watch line that's been in production since just before the turn of the century. This watch features a gorgeous dial that's hand engraved with incredible precision by a master Japanese craftsman using traditional techniques. It's quite a feat considering the hand-wound caliber 6899 and its parts are very thin, causing the engraver to have to work within incredibly tight tolerances. Even without polishing on the mainplate bridge, the watch glimmers with such beauty and depth at nearly every angle.
Japanese brands, especially Grand Seiko, have long been praised for producing watches that punch above their weight in terms of finishing. However, it's rare to find a mechanical reference that unites a small diameter with a thin case and an interesting dial. Credor's GBBD985 does just that with a skeletonized dial, 34.7mm diameter, and 5.7mm thickness, all of which contribute to a delightful wearing experience.
