Atlantic Worldmaster Open Heart Limited Edition: Swiss Craftsmanship in Anthracite and Rose Gold
There is something inherently captivating about a mechanical watch. Beyond telling time, it reveals the skill, patience and precision behind an object designed to endure. The Atlantic Worldmaster Open Heart Limited Edition brings that philosophy to the wrist with an understated combination of Swiss craftsmanship, contemporary design and mechanical artistry.
Its defining feature is the open-heart aperture at 12 o’clock, offering a glimpse of the movement beneath the dial. Rather than concealing the mechanics, the design makes them part of the experience, creating a subtle sense of movement and depth.


The 42mm polished stainless-steel case gives the watch a confident yet balanced presence, while its 10.3mm profile keeps the silhouette refined. An anthracite dial is paired with warm rose gold accents, luminous hands and indexes at 3, 6 and 9 o’clock, creating a sophisticated contrast without unnecessary embellishment.
At its centre is the automatic Sellita SW 200-1/OH movement, reflecting the precision and reliability associated with Swiss mechanical watchmaking. A sapphire crystal protects the dial, while the sapphire case back offers another view of the intricate mechanics within.
A genuine calf leather strap and butterfly clasp complete the design, bringing comfort and a polished finish. With 50 metres of water resistance, the watch is also designed to move easily through everyday occasions, from formal gatherings and dinners to business settings and weekends.
Limited to 888 pieces, the Worldmaster Open Heart carries an added sense of exclusivity for collectors and enthusiasts. Its combination of visible mechanics, restrained detailing and traditional craftsmanship gives it a personality that goes beyond specifications.
It also makes a considered gift for someone who appreciates fine watchmaking, whether marking a birthday, anniversary, wedding, promotion or personal milestone.
Ultimately, the appeal lies in its balance. The anthracite and rose gold palette provides quiet sophistication, while the open-heart construction reveals the intricate world that makes a mechanical watch so compelling.
The Atlantic Worldmaster Open Heart Limited Edition is a celebration of precision in motion — a timepiece where craftsmanship is not simply worn, but seen.
