BERSIGAR Polaris 1790: Silver Black Edition
The BERSIGAR Polaris 1790 Silver Black unites classic cockpit instrument heritage with modern monochromatic elegance. Defined by a balanced 42mm round case, an ergonomic 4 o'clock winding crown, a scratch-resistant black sapphire bezel insert, and a matte obsidian dial with a dedicated small-seconds sub-register at 6 o'clock, this automatic timepiece delivers timeless executive versatility and understated luxury.
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 deep black dial features applied faceted dagger indices, skeletonized leaf hands with strong luminous fill, and an internal black 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 black leather strap with a deployant folding clasp, and an offset screw-down crown providing 10 BAR (100M) water resistance.

From the journal
Owners say
I am a machinist and usually skeptical of $220 watches sold online, but the brushing on this 316L case and the sapphire bezel are well executed. Note that the high-beat automatic rotor has a slight audible whir in a dead-quiet room.
Coming from a machinist, that compliment on the case brushing means a lot, Jacob! That unidirectional rotor sound is normal for the 9020 series.
Checked timekeeping over ten days and the Japanese 9020 automatic is averaging +4 seconds per day. Case tolerances around the fixed black sapphire bezel are tight, crown action is firm, and the matte black dial has zero glare.
Four seconds a day is right where we like to see that 9020 caliber running, Lawrence! Thanks for the review.
Wore this with a charcoal suit to a city council meeting and it looked right at home. Sits flat enough on my wrist to clear my shirt cuff, though the black alligator-grain leather strap was pretty stiff for the first 3-4 days.
Thanks for the feedback, T.! Glad it paired well with your suit, and that leather strap will keep softening up with wear.
Got the Silver Black edition for my dad's birthday in Colorado. He likes classic black-dial field and pilot watches on leather, and he loved the small-seconds sub-register right away.
Clean black dial and smooth small-seconds hand. Fits my wrist well.
Getting a Japanese 9020 automatic with a sapphire crystal and sapphire bezel at $220 made me skeptical at first. Once I put it on my wrist, the solid 316L steel finishing and weight convinced me immediately.
Case measures right at 42mm with clean brushing on the 316L steel flanks and a flush black sapphire bezel. The Japanese 9020 automatic holds within a few seconds a day and legibility against the matte obsidian dial is strong.
Bought the Silver Black Polaris 1790 for my husband's birthday. He is super picky about automatic watches, and he wears this to the office almost daily. His only comment was the small-seconds subdial numerals are a little small without his reading glasses.
Happy birthday to your husband, Danielle! Glad the Silver Black 1790 passed his test, and we appreciate the note on the subdial markings.
