Poljot International Jaros Open Heart – limited to 100 pieces
With the Jaros Open Heart, Poljot International presents a classic mechanical timepiece that combines traditional watchmaking with subtle modern accents. The open dial offers a direct view of the beating heart of the watch – a detail that makes mechanical precision visible and appeals immediately to enthusiasts of automatic watches.
The silver dial with fine wave-shaped guilloché finishing adds depth and structure to the design.
At the center, the so-called open heart reveals the movement, framed by a bright ring made of genuine mother-of-pearl. This combination of visible mechanics and refined materials gives the watch a restrained yet distinctive presence.
The name “Jaros” is derived from historic Jaroslavl models and represents Poljot International’s commitment to classical design with a contemporary interpretation. The prominent numerals at 12, 3 and 6 introduce subtle modern accents, while the rose-gold-colored dauphine hands consistently underline the classic character of the watch.
Inside, the reliable Seiko NH38 automatic movement with 24 jewels is at work. This caliber is well known for its robustness, stable performance and smooth operation – suitable for everyday wear as well as for a collector’s watch.
