The watch
The Bersigar Polaris 1790 Silver Green is a 42mm pilot watch with an olive green dial, powered by a Japanese 9020 automatic movement. Highlights include a fixed green sapphire bezel, 100m water resistance and a sapphire crystal. On the ChronoSeasons dial it sits at Hour VI — Field & Adventure, part of the Expedition season — and suits frequent flyers and outdoor weekends.
BERSIGAR Polaris 1790: Silver Green Edition
The BERSIGAR Polaris 1790 Silver Green pairs vintage aviation instrument aesthetics with a distinctive earthy palette. Characterized by a 42mm round case, an ergonomic 4 o'clock winding crown, a scratch-resistant olive green sapphire bezel insert, and a textured green dial with a dedicated small-seconds sub-register at 6 o'clock, this automatic timepiece delivers relaxed versatility and tailored executive refinement.
Powered by the Japanese 9020 automatic mechanical movement, the self-winding caliber harnesses natural wrist kinetic energy to drive central hours, central minutes, and an independent running small-seconds subdial. The olive green dial is detailed with applied faceted dagger indices, skeletonized leaf hands with luminous fill, and an internal green sapphire bezel ring. Machined from solid 316L brushed and polished stainless steel, the watch is equipped with an anti-reflective sapphire crystal, an alligator-grain green leather strap with a deployant folding clasp, and an offset screw-down crown delivering 10 BAR (100M) water resistance.

From the journal
Owners say
I have a dozen microbrand field and dive watches, and this Polaris 1790 stands out for running a thin, high-beat Japanese 9020 automatic caliber. Having 100m water resistance, an anti-reflective sapphire crystal, and a matching green sapphire bezel at $220 is tough to beat. The small-seconds sub-register balances the olive green dial nicely, and lug-to-lug sits comfortably flat on my wrist.
Was hesitant ordering a $220 automatic online, but the glossy green sapphire bezel and solid 316L steel case look and feel like a much pricier piece. Runs accurately on my 7-inch wrist.
Swapped a waterproof canvas strap onto this for hiking and fly fishing. The 100m water resistance and green sapphire bezel handle wet weather and rocks easily, and the dial is super clear.
Picked up the green version after liking the blue one. Same tight 42mm case tolerances, scratch-resistant sapphire crystal, and steady timekeeping from the 9020 automatic on my wrist.
As a machinist and watch nerd, the Japanese 9020 automatic inside this 42mm Polaris 1790 is what sold me. It beats at 4Hz, winds smoothly, and has stayed within +4 seconds a day on my timegrapher. The olive green dial with the 6 o'clock small-seconds sub-register and green sapphire bezel look sharp on my wrist. Crown action was a little stiff out of the box before working it a few times.
Been wearing this to work and out on weekends. The olive green dial and matching green bezel look much richer in natural sunlight than on my laptop screen.
Thanks again, Steve! That olive green really comes alive in the Georgia sun.
The 42mm 316L steel case and fixed green sapphire bezel are machined cleanly, and the Japanese 9020 automatic movement winds without grit. High-contrast hands against the olive dial make it very legible on my wrist.
