Poljot-International’s Jaros Open Heart is a timepiece that blends classic watchmaking artistry with refined, sophisticated details.
The first thing that strikes you about the Jaros is the dial: a finely executed wave-pattern guilloché that plays with light and instantly draws the gaze toward the centre. Here, the “open heart” takes pride of place, framed by a rich, dark ring of genuine mother-of-pearl. It’s a compelling blend of traditional craftsmanship and natural refinement, brought together with effortless grace.
The name Jaros pays tribute to the historic Jaroslavl lineage and forms part of Poljot-International’s classically inspired collection. True to the brand’s heritage, this line retains the spirit of its predecessors while presenting it through a contemporary lens.
Sharp Dauphine hands underscore the watch’s timeless intent, and beneath the dial beats the ever-dependable Seiko NH38 mechanical movement—an expression of honest, traditional watchmaking. The open-heart aperture offers a direct view into the pulsating mechanics within, bringing the watch’s living rhythm to the forefront.
Large numerals at 12, 3, and 6 introduce a subtle modern edge without straying from classic design codes. Housed in a 42 mm stainless-steel case and paired with a finely embossed calfskin strap, the Jaros Open Heart stands as a refined yet fresh interpretation of the classic wristwatch. It is a piece of living tradition—elegantly updated for the modern collector.
