What to know

The Presage Japanese Garden HCB008J1 trades twilight-green warmth for a black-and-gold depiction of a Kyoto garden after dark. The large open-heart cutout reveals much of the 4R71 movement, while the opposite side of the dial carries a directional herringbone texture and applied Roman numerals.

This 41.8mm steel watch is 12mm tall, with a dual-curved sapphire crystal and black leather strap. The automatic movement is hand-windable, offers stop-seconds and provides roughly 41 hours of power. As a splash-resistant dress watch it is best kept away from water. Introduced in September 2026, Moonlight Black lists for €650 in Belgium.
