Hemel Airstream — 40mm Hand-Wound Pilot Chronograph (ST19)
The watch
The Hemel Airstream is a 40mm chronograph with a matte black dial, powered by a hand-wound mechanical chronograph movement. Expect 100m water resistance and a sapphire crystal. It belongs to Hour V, Chronograph, in our Expedition season: a natural choice for motorsport fans and aviation enthusiasts.
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.
Good to know
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.
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.
The case measures 40mm — a versatile size that suits most wrists (roughly 15.5-19 cm / 6.1-7.5 in). Our watch size guide (/pages/watch-size-guide) explains how to measure your wrist.
It has a matte black dial, under a sapphire crystal.
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.
On the ChronoSeasons dial it sits at Hour V — Chronograph, part of the Expedition season, and suits driving days, flights and timing anything that matters. It also appears in our Pilot & Aviation edit.
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.

Owners say
When I'm not in uniform flying, I wear this Airstream to meetings around DC with a navy suit or sport coat. At 40mm it has a clean, tailored profile that clears a dress cuff, while the twin white registers keep it interesting.
Got the Hemel Airstream for my father's retirement after 35 years in aviation maintenance. He loves hand-wound watches and was grinning ear to ear when he saw the reverse panda dial and exhibition back. Fits his wrist great.
This 40mm Airstream transitions easily from construction site walk-throughs in the morning to client budget meetings in the afternoon. The Italian leather strap and black-and-white dial look sharp with a button-down shirt, and the case doesn't catch on my cuffs.
Bought this for timing weekend backroad drives and track days near Detroit. The white sub-dials on the matte black background give it a great vintage dashboard gauge look, and the pushers feel crisp. The crown felt a little tight when winding for the first few days, but it smoothed right out.
Thanks for picking up the Airstream, D. Young! That reverse-panda dial really does feel right at home behind the wheel.
Wore the Airstream out on the boat around Tybee Island all weekend. The 100m water resistance gives me peace of mind around salt spray, the high-contrast reverse panda dial is readable in harsh sunlight, and the lume holds a solid charge after dusk.
In a collection full of Swiss automatics, the Hemel Airstream gets a surprising amount of wrist time on my wrist. The 40mm case has classic lug proportions, and the double-domed sapphire with AR coating shows off the crisp white sub-registers against the matte black dial with zero wash-out. The Seagull ST19 hand-wound movement is a joy to operate, resetting cleanly and averaging +5 sec/day over the past month.
The Airstream HF30 captures that mid-century aviation timer look without feeling oversized on my wrist. The white sub-registers pop against the matte black dial, the ST19 pushers have a firm mechanical snap, and the 12-hour bezel is great for tracking a second time zone.
