Meet the Hemel Air Defense Manual Winding Chronograph Watch, a refined member of the HF Series. Our newest hand winding chronograph provides a more open aesthetic to our timeless piano black dial. Simplified markers create room for larger subdials to emphasize the timing capabilities of this piece. Piston pushers and a double signed buckle complement the flexible Italian leather strap, making this chrono ready for all your adventures.
Design and Craftsmanship
From the 40 mm case to the polished 316L stainless steel housing, this watch blends rugged reliability with understated elegance. The matte black dial is paired with Super-LumiNova C3 for legibility in low light, while a double-domed sapphire crystal with AR coating reduces glare for easy reading. The 120-click ceramic bezel with C3 lume adds precise timing control, and the screwdown, exhibition, engraved caseback invites a view of the heart beating inside. Completing the instrument-inspired look are piston pushers and a double-signed buckle, matched to a flexible Italian leather strap for comfort and durability.
