Minase Mastercraft J3
Minase introduces the Mastercraft J3, a new model that refines the brand's philosophy of "ultimate simplicity" by reducing the dimensions and complexity of its predecessor, the M3. This iteration features a sleeker, slimmer case and a Japanese Miyota movement, aiming for accessible expression of the brand's signature hand-finishing.

The J3 is presented as an evolution of "ultimate simplicity," taking inspiration from the M3 but removing unnecessary details for a sleeker, smaller, and simpler design.
The 37mm case with a 9.9mm profile offers noticeably different proportions compared to the M3's 38.8mm diameter and 10.8mm thickness.
The case finishing features a mix of circular brushing and manual Sallaz polishing, creating distortion-free mirror surfaces and crisp transitions.
Minase replaced the Swiss Sellita SW200-1 movement with the Japanese Miyota 90S5, a 24-jewel caliber running at 28,800 vph with a 42-hour power reserve.
Dials are available in white, beige, or black with a fine sand-textured surface, featuring applied Sallaz-polished indexes and hands with blue luminous material.
The 18mm strap system uses a one-touch quick-change mechanism, compatible with various crocodile-pattern calfskin, embossed leather, rubber straps, and a stainless steel bracelet.
The watch's design evokes a 1970s feel through the combination of a round dial beneath sapphire crystal and an angular case.
