【Limited models of the year 2021】- VINTAGE COLLECTIONS
Since its founding, Maker's Watch Knot has been rewriting the standards of the wristwatch industry many times and continues to send innovative products to the world.
Following the philosophy of the flagship model 「AT-38」, the second automatic series AUTOMATIC CHRONOGRAPH "ATC-40" is now available. The movement is a mechanical chronograph movement with a super complex structure with two mechanisms that can measure with time by using about twice the number of parts of "AT-38". It is a movement that emphasizes durability and accuracy adopting column wheel type and vertical clutch type mounted on high class mechanical chronograph.
In addition, we prepared two can holes in the lug part for attaching the strap. You can enjoy a separate type in the upper hole and a strapping type with the lower hole. It stabilizes the center of gravity balance of the whole clock and enhances fitness to the arm.
Same as "AT-38", the case is handling the manufacture of the forest device which manufactures the case of domestic best mechanical watch. "Sallaz Polishing" giving a beautiful flat finish without distortion is a mirrored polishing technology that is proud of worldwide production of forest insects that is rarely used even in Japanese luxury watches.
This year in 2021, new color has released. The most attractive feature of this vintage model is the dial, with tanned and aged color treatment. In order to faithfully reproduce this texture, we have adopted the cold forging method, in which tons of high-pressure press are directly applied to the brass. The gradation of the outer circumference gives the watch a vintage look that can been joyed for years.
