It uses the Seiko YN55A automatic movement, a self-winding mechanical caliber that stays running from the natural motion of your wrist with no battery to replace.
Can I swim with the Hemel Nitro?
Yes. With 200m of water resistance it is dive-ready and fully at home with swimming, snorkeling and recreational diving.
Will the Hemel Nitro fit my wrist?
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.
How does the Hemel Nitro's 40mm case feel on the wrist?
The 40mm case wears true to size and versatile, and the stainless steel jubilee bracelet gives it a comfortable, everyday drape.
What is the character of the Nitro?
It is a spirited automatic field watch on a jubilee bracelet, finished with a domed AR-coated sapphire crystal for a clear, characterful read of the dial.
Who is the Hemel Nitro for?
On the ChronoSeasons dial it sits at Hour IX — Everyday, part of the Downtime season, and suits daily wear from morning to evening.
Is the Hemel Nitro authentic, and what warranty is included?
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.
I fly commercial routes out of Seattle and wanted a tough 40mm automatic I wouldn't have to baby on layovers. The rotating bezel is handy for quick elapsed time checks, the 200m water resistance handles hotel pools, and the Classic Blue dial is super legible.

Comfortable jubilee and sharp blue dial
Sized the jubilee for my 7.75-inch wrist in five minutes. Great daily automatic.

blue dial pops in sunlight
Been wearing the Nitro to the office and out on weekends. The Classic Blue dial has a much richer tone in real sunlight than in the website photos, and the jubilee bracelet feels great on my wrist.

clean vintage rally vibe
The bezel markings and bold dial layout on the Classic Blue Nitro give it a cool vintage motorsport timer feel for weekend drives down A1A. The Seiko YN55A automatic has been rock solid. Shipping carrier delayed the box by two days, though the watch itself is great.

Thank you for your patience with the carrier delay, Alexander! Glad the Classic Blue Nitro was worth the extra two days of waiting.

looks great on leather too
The factory steel jubilee bracelet is comfortable on my wrist, but I also tried it on a 20mm dark brown leather strap for a dressier look. The leather strap I put on was pretty stiff for the first 3-4 days before breaking in, though the Classic Blue dial looks sharp on both.

Great 40th birthday gift for my brother
Picked up the Classic Blue Hemel Nitro for my brother's 40th birthday last month. He wanted an everyday automatic on a jubilee bracelet that could handle swimming with his kids, and the 200m rating plus that deep blue dial made it a home run.
