Horology By The Sea is proud to present this absolutely mint example of the Czapek & Cie Antarctique Titanium "Dark Sector"—a masterclass in monochromatic styling and architecture.
This particular iteration is encased in Grade 5 titanium, offering a featherweight 95-gram presence on the wrist.The dial is where the "Dark Sector" truly earns its moniker, utilizing a grey velouté brass surface with a unique segmented layout where the hour markers are defined not by indices, but by the physical voids between two rows of arched, parallel segments. The integrated bracelet is equally refined, featuring the "C" shaped center links and a clever micro-adjustment system within the clasp, while the "Easy Release" system allows you to swap straps in seconds.
Turning the watch over reveals Czapek's Calibre SXH5, their first fully in-house automatic movement by way of a micro-rotor crafted in .950 Platinum. Known as one of the more beautiful automatic movements in the biz, six of the seven sandblasted black bridges are skeletonized to provide a plunging view of the gear train. The escapement operates at 4Hz and delivers a power reserve of 60 hours.
The Grade 5 titanium case measures 40.5mm x 10.6mm x 45mm lug-to-lug and is in mint condition. The titanium bracelet is with full links and also appears to be in completely mint and unworn condition. Complete with Box & Papers dated October 5, 2025 and furnished with an additional grey rubber strap and Czapek pin buckle.
