Our watches mainly feature a Seiko NH35 automatic movement (or NH34 for GMT models), renowned worldwide for its reliability and longevity. For open-heart watches, we use the NH38 movement, and for skeleton watches, the NH72. Our chronograph models, on the other hand, have a VK63 quartz movement. Each movement is adjusted and tested in the workshop before shipment to guarantee optimal precision upon receipt.
