Hemel Airstream — 40mm Hand-Wound Pilot Chronograph (ST19)
About this watch
The Airstream is Hemel's Air Support collection at its most complete: a hand-wound ST19 column-wheel chronograph with a tachymeter scale, jumbo crown and Italian leather strap. Oversized subdials and a bold layout make it read like a proper racing-and-flight instrument, while the double-domed sapphire and exhibition caseback show off the mechanics beneath.
40mm polished 316L steel, 45-hour power reserve, 100m water resistance, ceramic 120-click bezel and matte black C3-lumed dial. New, boxed and warrantied — free US shipping.
Questions & answers
What movement powers the Airstream?
It is driven by the Seagull ST19, a hand-wound mechanical chronograph caliber - you wind it by the crown, and it stops and times intervals with a classic column-wheel feel.
Can I wear it in water?
With 100m of water resistance it shrugs off rain, splashes and hand-washing and is fine for a swim. We suggest avoiding hot showers, saunas and diving.
How does the 40mm case wear?
At 40mm it wears true to size with balanced, vintage-pilot proportions that suit most wrists.
What defines the Airstream design?
It is a hand-wound pilot chronograph with a matte black dial, double-domed AR-coated sapphire crystal and an Italian leather strap - tool-watch heritage with a refined finish.

Yes. This Hemel is sourced through Shopify Collective and Hemel's verified channel, so it ships brand-new, boxed and backed by a 2-year limited warranty. US orders include free insured shipping.
