The watch

Expect a fixed sapphire bezel, 100m water resistance and a sapphire crystal. We place it at Hour VI (Field & Adventure) of the Expedition season, for frequent flyers and outdoor weekends.
BERSIGAR Polaris 1790: Silver Blue Edition
The BERSIGAR Polaris 1790 Silver Blue blends classic aviation elegance with modern sports versatility. Characterized by a 42mm round case, an offset 4 o'clock winding crown, a scratch-resistant blue sapphire bezel insert, and a sunburst midnight-blue dial with a dedicated small-seconds sub-register at 6 o'clock, this automatic timepiece balances vintage instrument styling with tailored executive refinement.
Powered by the Japanese 9020 automatic mechanical movement, the self-winding caliber harnesses natural wrist kinetic energy to power central hours, central minutes, and an independent running small-seconds subdial. The fumé-finished blue dial is detailed with applied faceted dagger indices, skeletonized leaf hands with strong luminous fill, and an internal 60-minute sapphire bezel scale. Machined from solid 316L brushed and polished stainless steel, the watch is equipped with an anti-reflective sapphire crystal, an embossed alligator-grain blue leather strap with a deployant folding clasp, and an offset screw-down crown delivering 10 BAR (100M) water resistance.

From the journal
Owners say
Love the vintage aviation look of the 42mm case and the small-seconds sub-register at six. The fumé blue dial catches light nicely on my wrist. Shipping carrier delayed the box by two days, though the watch itself is great.
No play in the crown stem, clean brushing on the 42mm 316L steel case, and clear anti-reflective coating on the sapphire glass. The 9020 automatic has been steady and reliable on my 7.5-inch wrist.
Thanks Matthew! Glad the build tolerances and 9020 movement are performing well for you.
Finding a Japanese 9020 automatic movement under $250 is rare enough, and pairing it with a sapphire crystal and fixed sapphire bezel makes this Polaris 1790 a strong value in my collection. The 28,800 bph sweep on the small-seconds register at 6 o'clock is smooth, and the fumé blue dial transitions nicely from bright navy in the center to dark midnight at the flange. Wears comfortably on my wrist.
Bought this for my brother when he passed the bar exam. The smoked fumé blue dial and small-seconds subdial look sharp in a courtroom, and he was pumped to get a real automatic.
The stock blue alligator-grain leather looks dressy, and swapping on a navy sailcloth strap with white stitching turned it into a great coastal weekend watch on my wrist.
Purchased the Silver Blue Polaris for my son's 40th birthday. He wears blue suits to work almost every day, and when he opened the box he immediately swapped it onto his wrist.
The Japanese 9020 movement has kept within +6 seconds a day since arriving, and the fixed sapphire bezel lines up cleanly with the case. Only downside is the blue leather strap was pretty stiff for the first 3-4 days before breaking in.
Measured the 316L steel case at 42mm with clean lug bevels and a flat anti-reflective sapphire crystal. The 9020 automatic winds smoothly at the crown, and the sunburst fumé blue dial is easy to read on my wrist.
