Presented at the 2026 Watches and Wonders, the Czapek Antarctique S Dark Sector Cosmic Blue offers a refined, more compact take on this innovative luxury sports watch, maintaining the same striking design language in a slightly smaller profile. The Cosmic Blue dial, finished with a soft velouté texture, creates a layered visual effect, while the open sector-style hour track introduces a contemporary twist on a classic watchmaking concept. Driven by the in-house SXH5 automatic micro-rotor movement, this Swiss-made timepiece ensures precision, durability, and a 60-hour power reserve, making it an ideal choice for collectors who prefer a more understated wrist presence. If you are drawn to a larger case size, you can also view the 40.5mm edition of the Antarctique Dark Sector here.

A limited edition of 10 pieces.

Despite its smaller dimensions, the 38.5mm Antarctique retains the full technical and aesthetic impact of the collection. The exhibition caseback showcases the beautifully finished movement, with its skeletonized bridges and recycled platinum micro-rotor delivering both performance and visual intrigue. Paired with an integrated titanium bracelet featuring an easy-release system and micro-adjustment, this luxury sports watch offers exceptional comfort and adaptability. With only 10 pieces produced in this size, the Antarctique Dark Sector Cosmic Blue “S” stands as an ultra-exclusive addition to any serious watch collection.
