The Seiko Eichi II is perhaps the ultimate in Japanese watchmaking, a delicately simple timepiece executed with an exceptional devotion to quality and refinement. As movement finishing goes, the Eichi II is up there with the greats.
Steel screws used in watch movements are often blue. Traditionally this is done by heating the screws, hardening them and also giving them an attractive blue colour, a process Henrik Korpela explains in this in-depth article.
Black polishing, also known as spéculaire finishing, is employed to finish steel parts in a watch movement to create a mirror-like surface. Used for steel screws, levers and bridges, true black polishing is done by hand and only found in the best timepieces. Henrik Korpela explains the technique here.
EXCLUSIVE: Introducing The Seiko Credor Eichi II – The Finest Three-Hand Watch Made In Japan, And Possibly The World (With Specs And Price)Seiko has just announced the long anticipated Credor Eichi II, featuring a slim, 39 mm platinum case. A hand-wound, time-only wristwatch with a remarkably fine movement finish, the Eichi II is to mark the 40th anniversary of the Credor line and the 15th anniversary of the Spring Drive movement.
Greubel Forsey unveiled the stunning Tourbillon 24 Secondes Contemporain at SIHH 2012. Rather than a whole new movement, this is a variant of the Tourbillon 24 Secondes which has a single, inclined tourbillon cage that completes one revolution in a speedy 24 seconds.
Made by the Micro-Artist Studio at Seiko-Epson in Shiojiri, the Seiko Credor Spring Drive Minute Repeater is a hand-made and hand-finished to the most obsessive standards. As I wrote earlier in my article on the Credor Eichi, the movement finish executed at the Micro-Artist Studio is done according to the tutelage of no less than Philippe Dufour.
