Mastercraft J3
The Mastercraft J3 collection is inspired by one of Minase’s earliest creations, the iconic M3. All Minase ingredients are here : precision engineering, meticulous hand-finishing and timeless proportions. Better, every line has been refined, every surface considered. The result is a mechanical watch that expresses the quiet elegance of Japanese craftsmanship.
Light Sand Dials
The Mastercraft J3 is available in three dial colors: white, beige and grey, all developed to create subtle depth and a soft interaction with light depending in the viewing angle and environment. Sharp-cut hands create a refined contrast against the sand-textured dial surface, adding subtle dimensionality to the minimalist design. To enhance the visibility, both indexes and the hands are treated with blue luminescent material.
Minase Philosophy
An attention to details that cannot be achieved through mass production is the heart of Minase’s philosophy. The Mastercraft J3 pays tribute to Japanese craftsmanship featuring steel parts meticulously hand-polished with the Sallaz technique, known for producing distortion-free mirror surfaces and sharply defined edges. With its cushion-shaped case and round dial opening, the Mastercraft J3 evokes a sense of classic elegance reminiscent of the 1970s.
Japanese Movement
For the first time in the brand’s history, Minase’s J3 series features a Japanese movement. The J3 is powered by the MIYOTA 90S5 automatic movement. Made by Citizen and launched in 2019, it is a popular and reliable engine and consists in an affordable alternative to Swiss calibers.
